Comparison of the results of the performance and the sum of the sum of array elements

I did a comparison of the performance of "Add table" with 2 other methods (an Add elements and function of ddot BLAS) to see who was the fastest and also to compare their results, given that I was watching a few slight differences.

BLAS ddot's quicker (just a little), then add items, then add it in a loop of table

BLAS ddot and add items table give identical results almost all the time.

I don't know why add items in a loop manually gives a slightly different result. I understand there are any rounding due to finite precision errors, but why is it different for the 2 other methods?

This classic of digital computing: the quality of the result depends on the order of operations.

A simple example is the calculation of a * b / c with a, b, c equal to 25, 200 and 100 respectively. The result should be 50, but if a, b and c are U8, the result depends on the order of operation, as shown in the example below. DBL and data non-entier, the difference is of course that much smaller, but still there are!

In your case, the difference also stems from the order of operations:

-in the table add-in, the product of all the elements is calculated first and then the elements of the array are added.

-in the loop, the addition is performed after each multiplication.

  • A fundamental question/problem with the like undefined array element

    Hello everyone,

    Thanks for looking at my problem. I am very new script and javaScript, and I encountered a strange problem. I always try to solve all my problem myself, with documentation (it helps to learn) or as a last resort with the help of google. But in this case, I'm stuck. I'm sure its something very simple and elementary.

    Here I have a code that simply loads a text file (txt), load the contents of the file in a "var glad." This summary text file a font family name, every name on a new line, as:












    Blackoak... .etc

    Now I hollow the variable content of loop, extract each letter and add it to the list '[i]' table. If the character is a line break the list [i] table adds another element (i = i + 1); That's how I separate each name in its own element of array.

    The problem I encounter is, when I have hollow loop table fontList and $.writeln (fontList [i]) is the result in the console :




    undefinedArial... etc.

    I don't get serious, where the undefined comes? As far as I tested each digit to be added to the array element, I see nothing extraordinary.



    Here is my code:

    #target illustrator

    var doc = app.documents.add ();

    Open the file

    var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");

    openFile var = ("r");

    check if it is open

    if(OpenFile == true) {}

    {$.writeln ("the file has loaded")}

    else {$.writeln ("the file does not load, check the name or the path") ;}}

    load the contents of the file into a variable

    var content = ();

    myFile.close ();

    var ch;

    var x = 0;

    var fontList = [];

    for (var i = 0; i < content.length; i ++) {}

    ch = content.charAt (i);

    If ((ch)! == (string.fromCharCode(0)) (10))) {}

    fontList [x] += ch;


    else {}

    x ++;



    for (i = 0; i < fontList.length; i ++) {}

    $.writeln (fontList [i]);


    doc. Close (SaveOptions.DONOTSAVECHANGES);



    Thanks for any help or an explanation. If you have any tips on how to improve my practices or any suspicion, please do not hesitate to say. Thank you

    Hi vladac54380629,

    better, you try something like this:

    #target illustrator
    //var doc = app.documents.add(); 
    //open file
    var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");
    var openFile ="r"); 
    //check if open
    if(openFile == true){
        $.writeln("The file has loaded")}
    else {$.writeln("The file did not load, check the name or the path");} 
    //load the file content into a variable
    var fontList = []; 
    var content =;
    fontList = content.split ("\n")
    for ( i = 0; i < fontList.length; i++) {
    //doc.close (SaveOptions.DONOTSAVECHANGES);

    Have fun

    A note:

    The real font names may be different from your own list for example:

    Arial! = ArialMT

    Birch! = BirchStd

    Blackoak! = BlackoakStd

    Planning your Partitions

    The Question

    Partitions, how much should I have on my hard drive, what do I use
    each of them for, and what size should each one be?

    It s a common question, but unfortunately this doesn t have a
    only simple, just answer to all the world. A lot of people will respond with
    the way they do, but their response isn't necessarily best for the
    person seeking (in many cases it isn't right even for the person)


    First, let's rethinking the terminology. Some people ask "should I".
    partition my drive? That s the wrong question, because the
    the terminology is a little strange. Some people think that the word
    "partition" means divide the drive into two or more partitions.
    That s not correct: to partition a drive is to create one or several
    partitions on it. You must have at least one partition to use
    He who think they have an unpartitioned disk actually
    have a player with only one partition on it and it s normally
    Called C:. The choice you have is to have more than one
    partition, not that it's the partition at all.

    A bit of history

    Back before Windows 95 OEM Service Release 2 (also known as Windows
    95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
    using the file system FAT16 (except for very tiny to aid
    FAT12). That 16-bit only because were used for addressing, FAT16 has a
    maximum 2 GB partition size.

    More than 2 GB of hard disks were rare at the time, but if you had
    one, you must have multiple partitions to use all the available
    space. But even if your drive was not larger than 2GB, FAT16 created
    Another serious problem for many people - the size of the cluster has been
    more great if you had a larger partition. Cluster sizes increased from 512
    bytes for a partition to no greater than32Mb all the way up to 32 KB for a
    partition of 1 GB or more.

    More the cluster size, the space more is wasted on a hard drive.
    That s as space for all the files is allocated in whole clusters
    only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
    greater than 32 k byte takes 64 k and so on. On average, each file
    about half of his last group waste.

    If large partitions create a lot of waste (called "soft"). With a 2 GB
    FAT16 drive in a single cluster, if you have 10,000 files, each
    lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
    back in an important part of a player that probably cost more than $400
    1996 - around $ 32.

    So what did the people? They divided their 2 GB drive in two,
    three or more logical drives. Each of these logical drives has been
    smaller the real physical disk, had smaller clusters, and
    so less waste. If, for example, she was able to keep all the partitions
    less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
    a quarter of what it would be otherwise.

    People partitioned for other reasons also, but back in the days of
    FAT16, it was the main reason to do so.

    The present

    Three things have changed radically since 1996:

    1. the FAT32 and NTFS file systems came along, allowing a larger
    partitions with smaller clusters and so much less waste. In
    with NTFS, cluster sizes are 4 K, regardless of the size of the partition.

    2 hard drives have become much larger, often more than 1 TB (1000 GB) in

    3 hard drives have become much cheaper. For example, a 500 GB drive
    can be bought today for about $50. That s 250 times the size of this
    Player 2Gb typical 1996, about one-eighth of the price.

    What these things mean together which is the reason to be old to have
    multiple partitions to avoid the considerable wastage of disk space left.
    The amount of waste is much less than it used to be and the cost of
    that waste is much less. For all practical purposes, almost nobody does
    should no longer be concerned about slack, and it should no longer be
    has examined when planning your partition structure.

    What Partitions are used for today

    There are a variety of different ways people put in place several
    scores of these days. Some of these uses are reasonable, some are
    debatable, some are downright bad. I'll discuss a number of Commons
    partition types in the following:

    1. a partition for Windows only

    Most of the people who create such a partition are because they believe
    If they never have to reinstall Windows properly, at least they
    He won t lose their data and he won t have to reinstall their applications.
    because both are safe on other partitions.

    The first of these thoughts is a false comfort and the second
    is downright bad. See the analysis of the types of partition 2 and 4
    below to find out why.

    Also note that over the years, a lot of people who find their windows
    partition that has begun to be the right size proves to be too
    small. For example, if you have such a partition for Windows and later
    upgrade to a newer version of Windows, you may find that your Windows
    partition is too small.

    2. a partition for installed programs

    This normally goes hand in hand with the partition type 1, a partition for
    just Windows. The thought that if you reinstall Windows, your
    installed application programs are safe if they are in another
    partitions is simply not true. That s because all programs installed
    (with the exception of an occasional trivial) have pointers to the inside
    Windows, in the registry and elsewhere, as well as associated files
    buried in the Windows folder. So if Windows, pointers and
    the files go with it. Given that the programs need to be reinstalled if Windows
    the fact, this reasoning to a separate partition for programs not
    work. In fact, there is almost never a good reason to separate
    Windows of the software application into separate partitions.

    3. a partition for the pagefile.

    Some people think mistakenly that the pagefile on another
    score will improve performance. It is also false; It doesn t
    help and often I hurt, performance, because it increases the movement of the head
    to get back to the page to another file frequently used
    data on the disk. For best performance, the paging file should normally
    be on the most widely used score of less used physical player. For
    almost everyone with a single physical disk than the same drive s
    Windows is on C:.

    4. a partition for backup for other partitions.

    Some people make a separate partition to store backups of their other
    or partitions. People who rely on a "backup" are a joke
    themselves. It is only very slightly better than no backup at all.
    because it leaves you likely to be simultaneously the original losses
    and backup for many of the most common dangers: the head crashes and other
    types of drive, serious glitches to power failure, near lightning
    strikes, virus attack, even stolen computer.  In my opinion,.
    secure backup must be on a media removable and not stored in the

    5. a partition for data files

    Above, when I discussed separate Windows on a clean partition,
    I pointed out that separate data from Windows is a false comfort if
    He of done with the idea that data will be safe if Windows ever
    must be reinstalled. I call it a false comfort that's because
    I'm afraid many people will rely on this separation, think that their
    data are safe there and so do not take measures to
    Back it up. In truth the data is not safe there. Having to reinstall
    Windows is just one of the dangers to someone a s hard disk and not
    probably even one. This kind of "backup" falls into the same
    category, as a backup to other partitions partition; It lets you
    sensitive to the simultaneous loss of the original and the backup on many of
    the most common dangers that affect the entire physical disk, not
    just the particular partition. Security comes from a solid backup
    diet, not how partition you.

    However, for some people, it may be a good idea to separate Windows and
    programs on the one hand of the data on the other, putting each of the
    two types into separate partitions. I think that most people
    partitioning scheme must be based on their backup system and backup
    plans are generally of two types: whole hard disk imaging
    or data only backup. If you back up data, backup is
    usually facilitated by the presence of a separate with data only partition;
    to save just the score easily, without having to
    collect pieces from here and elsewhere. However, for
    those who backup by creating an image of the entire disk, there is
    usually little, if any, benefit the separation of data in a partition of
    its own.

    Furthermore, in all honesty, I must point out that there are many
    very respected people who recommend a separate partition for Windows,
    Whatever your backup plan.  Their arguments haven t convinced
    me, but there are clearly two views different here.

    6. a partition to image files

    Some people like to deal with the images and videos as something separate
    other data files and create a separate partition for them. To my
    the spirit, an image is simply another type of data and there is no
    the advantage in doing so.

    7. a partition for music files.

    The comments above related to the image files also apply to music
    files. They are just another type of data and must be dealt with the
    just like the other data.

    8. a partition for a second operating system to dual-boot to.

    For those who manage several operating systems (Windows Vista, Windows
    XP, Windows 98, Linux, etc.), a separate partition for each operating
    system is essential. The problems here are beyond the scope of this
    discussion, but simply to note that I have no objection to s
    all these partitions


    Some people have several partitions because they believe that it
    somehow improves performance. That s not correct. The effect is
    probably low on modern computers with modern hard disks, but if
    whatever it is, the opposite is true: more music mean poorer
    performance. That's because normally no partition is full and it
    so are gaps between them. It takes time for the drive s
    read/write heads to cross these gaps. Close all files
    are, faster access to them will be.


    I think a lot of people overpartition because they use scores as a
    organizational structure. They have a keen sense of order and you want to
    to separate the apples from the oranges on their readers.

    Yes, separating the different types of files on partitions is a
    technical organization, but then is to separate different types of
    files in folders. The difference is that the walls are static and
    fixed in size, while the files are dynamic, changing size automatically
    as needed to meet your changing needs. This usually done records
    a much better way to organize, in my opinion.

    Certainly, partitions can be resized when necessary, but except with the latter
    versions of Windows, which requires a third-party software (the and the
    possibility to do so in Windows is primitive compared to the third-party
    solutions). These third party software normally costs money and not
    any point and how stable it is, affects the entire disk.
    with the risk of losing everything. Plan your partitions in
    first place and repartitioning, none will be necessary.  The need
    to repartition usually occurs as a result of overpartitioning in
    the first place.

    What often happens when people organize with partitions instead
    records are that they make a miscalculation of how much room they need on each
    This partition, and then when they run out of space on the partition
    When a file is logically, while having plenty of space
    on the other hand, they simply saving the file in the score of "poor".
    Paradoxically, therefore, results in this kind of score structure
    less organization rather than more.

    So how should I partition my drive

    If you read what came before, my findings will not come as a

    1. If your backup set is the image of the entire disk, have just one
    single (usually c partition :));

    2. If you backups just data, have two partitions one for Windows and
    application programs installed (usually c :)), the other for data
    (normally D :).)

    With the exception of multiple operating systems, it is rarely
    any advantage to have more than two partitions.

    You think you're going to lines updates 85K, Oracle think it will update a line.

    At the time where the existence of the first test runs that oracle think already up to 49 lines, which is probably why he uses the loop join nested for the second test. (In your version of Oracle, the subquery introduced existence a very bad assumption (small) on the amount of data will survive).

    It is possible that you will get better performance if you hint Oracle using a hash join for testing the existence - and you might want to think what test will eliminate most of the data and that we can first force.

    Having said that, however, note that MMR_DTL research is a considerable fraction of the cost of the query - and an analysis is an easy thing for Oracle cost properly - if, despite your comments on update a column with a clue to this topic, you will find that the query can be more effective if you use an index. This is more likely to be the case if data ' WHERE CAPITN_PRCS_IND = 5 AND HSPC_IND = 'Y' "is well grouped (perhaps the latest data added to the table).". "  You could then reduce the cost of maintaining this index by creating an index based on a feature that indexes only the lines where the predicate are both true so that the 2 update deletes the index entries and allows the index remain as thin as possible.

    Oh - and regarding the materials on 1Z0 - 064, there is not yet any material of third parties specific to 1Z0 -054 out right now.  I am sure that there is no output for 064 yet.  I will create a guide for it shortly... I hope that I will be able to complete before the beta and take the exam at the end of the beta.  However, I concentrate on my exams to practice at the moment... so I don't even know if I'll make this deadline.  I certainly will not post before the end of the beta review and probably not until the review of the production is released.

  • Big client - vCenter 5.5 response time of the customer Web U1c / questions of Performance and Navigation

    So we're all aware of the issues with vCenter 5.5U1 WebClient and how we are forced to use it to make use of all the features of the v10, vDS 5.5 vHardware (config switch changes the synchronization problems if an emergency change is done on c# client vDS) VSAN only available via the web client, flash, sluggish to questions do not respond the questions and the list goes with the presentation of the menus and hard to navigate, issues SSO (always after 5.5 upgrades)

    So @ VMware vCenter Architecture Team is going to make an effort to hear and give due to the much needed performance improvements and improvements to the user interface before adding more features and SSO type services which majority of clients don't use not and not force it's customers continue to loose faith its vCenter product?

    Looking for answers with options to remove vCenter 5.5 U1c installation as well as a promise to answer to these in vCenter 6.0 version!

    Here is your answer. First of all, to use Chrome as your browser, then you need to go with at least 4vCPU * 32 GB of RAM & adjust the segment size of java for SSO, Tomcat, (TC) Management Server, inventory server and profile based storage to "refine" vCenter device with DB Oracle embedded or external memory. I did, and performance gains went 10 X. This includes the vSAN enabled running clusters. My recommendation that works very well based on design documents:

    vCenter Server inventory

    VMware VirtualCenter Management Webservices (tc Server)

    The inventory service

    (Sps) profile-based storage service

    Large (more than 400 guests or 4000 VMS) stock

    4 GB

    12 GB

    4 GB

    Setting on the vCenter server 5.5 of the memory unit

    • Connect the unit to vCenter server using SSH
    • VI /usr/lib/vmware-vsphere-client/server/wrapper/conf/wrapper.conf configuration file, locate the JVM memory section and change maxmemory to 4096
    Line 66 # Memory = = 4096 JVM
    • /usr/lib/vmware-vpx/inventoryservice/wrapper/conf/wrapper.conf VI configuration file, find the setting. MaxMemory and replace it with 12288
    Line 116 # Size (in MB) maximum Java heap = 12288
    • VI /usr/lib/vmware-vpx/sps/wrapper/conf/wrapper.conf find the setting. MaxMemory and change from 1024 to 4096
    On line 154 # Size (in MB) maximum Java heap = 4096
    • Restart the vCenter device w / DB (1000 hosts) external /embedded for lab (100 guests)

    PS: vCenter 6.0 has much better performance based on my beta test... so don't lose hope yet. Many improvements to come...

    PS: I've also broken down on this here until I figured this out just recently: Re: big client - vCenter 5.5 response time of the customer Web U1c / questions of Performance and Navigation

  • The difference b/w maximum performance and maximum availability


    What is the basic difference b/w maximum performance and maximum availability.
    If maximum performance scenarios is used and ensures db stops, changes in the primary db will apply to the next time you start backup db.



    I have read all answer your thread.

    If you create a broker - managed DataGuard configuration, you can use
    quick start failover (FSFO) for your dataguard.
    When your primary is down, your sleep will change primary role.

  • Comparison of the two bays and change alpha to the array element?


    I continue to work on improving my code ("do more with less"), but ran into a problem.

    I try to have some cases become visible when the mouse over other forums (as if the 'campScene.goToAxSign' becomes visible once the mouse is on "campScene.goToAx"). I have two tables; "hoverDetectArray" handles instances "goToX"and "hoverInfoArray" handles instances "goToXSign.

    hoverDetectArray = [campScene.goToAx, campScene.goToBridge, campScene.cantGo];

    hoverInfoArray = [campScene.goToAxSign, campScene.goToBridgeSign, campScene.cantGoSign];

    The event listener constantly listening for any changes.

    addEventListener (Event.ENTER_FRAME, SceneHoverInfo);

    I have also two functions (although if there is a way to do this with one, please let me know), "SceneHoverInfo" and "SceneHoverInfo2". I am able to do "SceneHoverInfo" works correctly (at least drawing, not my final goal) if I add an event listener for the second function.

    public void SceneHoverInfo(event:Event) {}

    for (var i: uint = 0; i < hoverDetectArray.length; i ++) {}

    If (hoverDetectArray [i] .hitTestPoint (mouseX, mouseY, true)) {}

    trace ("cheese");

    } else {}





    However, I get the error 'term is undefined' if I write this:

    If the mouse is hovering

    public void SceneHoverInfo(event:Event) {}

    for (var i: uint = 0; i < hoverDetectArray.length; i ++) {}

    If (hoverDetectArray [i] .hitTestPoint (mouseX, mouseY, true)) {}

    addEventListener (Event.ENTER_FRAME, SceneHoverInfoAlso);

    } else {}

    removeEventListener (Event.ENTER_FRAME, SceneHoverInfoAlso);




    sign to view

    public void SceneHoverInfoAlso(event:Event) {}

    for (var e:uint = 0; e < hoverInfoArray.length; e ++) {}

    .Alpha hoverInfoArray [e] = 1;



    I don't know there is something I'm missing, as for the comparison of the two tables. I was hoping somehow the installation program, ' if the mouse is positioned on stationary pointDetectArray [0], castInfoArray [0] to be visible.»

    Help is appreciated, as always, and let me know if you need more information.

    Geez, sorry, my bad. It was a problem of naming error that I do not. However, I must point out that functions still do not work the way I want. I am only able to do the alpha = 0 if I hover over the first element of hoverDetectArray [i] (although a trace works on all levels to detect three); others don't seem to be listening. I will continue to work on that.

    What is the full error message?  Make sure you go in your publication of PFlash settings and select the option to enable debugging so that your error message provides more complete information when possible.

    EDIT: Welp, IT solved. The key was simply re-use i like the whole (since both "line up" quite a bit) and not worry a statement 'for' for hoverInfoArray.

    public void SceneHoverInfo(event:Event) {}

    for (var i: uint = 0; i

    If (hoverDetectArray [i] .hitTestPoint (mouseX, mouseY, true)) {}

    hoverInfoArray [i] .alpha = 1;

    } else {}

    hoverInfoArray [i] .alpha = 0;
