So, for example, if you issue the command matlabpool open local that will start as many workers as you have cores on your machine. The local scheduler keeps track of how many workers are running, and will not exceed the number of cores on your machine. Cheers, Edric.

Yes, it's called MATLAB. http://www.mathworks.com/products/matlab/ If you're looking for the MATLAB equivalent of Java's free JVM: http://www.java.com/en/download/index.jsp the closest equivalent is the MCR, but that's only for use with applications deployed using MATLAB Compiler, not for execution of general MATLAB programs.

Hi, I have a question regarding using compiled Matlab executables. I have a compiled Matlab code that runs. When the code runs, it creates a folder inside "T:\Temp\mcrCache7.14". For some reason I have to erase that directory every time I need to run the code, otherwise, it fails. So I wrote a PERL script to call the Matlab executable and to handle the erasing of the directory inside the mcrCache directory. All is well so far. The problem is that now I am running such Matlab compiled code in parallel, and I guess now that creates a problem. Now, the PERL scripts might erase the mcrCache while other PERL script is still running! Questions: 1) I wonder why we even need that mcrCache in the first place. Why can't Matlab just compile an executable that contains everything it needs (self-contained) and that runs locally??? 2) If the mcrCache is something that is needed and I can't take away (see question 1), then how do I handle this problem of running in parallel a compiled Matlab program? Any help in this matter is appreciated. Thanks, Noel Andres ...

If you're using the Student Version of MATLAB, Parallel Computing Toolbox is available as an add-on product. http://www.mathworks.com/academia/student_version/companion.html Note that MATLAB Distributed Computing Server is NOT available as an add-on product, so I don't believe you will be able to connect multiple machines to create a cluster using Student Version. You should be able to use a local cluster, though. If you're using the Professional Version of MATLAB using Clemson University's license, you will need to check with the IT staff that are responsible for maintaining that license to determine if Parallel Computing Toolbox is included in the license or to discuss setting up a trial version of the toolbox if it is not. -- Steve Lord slord@mathworks.com To contact Technical Support use the Contact Us link on http://www.mathworks.com ...

Hi,all; I have one question about increasing computation speed for matlab programme. I have one Matlab programmer which last for almost 5 hours. If I write part of codes in Fortran and calling those codes in the main m file, is there any significant improvement of the computation speed taking place? or in other word, will fortran codes run much faster compared to the matlab? any comment on this subject is greatly appreciated. thanks, edwards Take a look for: help profile This gives a possibility to check the code for time consuming lines. Sorry, but I do not know about decreasing computation time by using fortran functions.

Hi everyone! I recently purchased a new computer (a mac running Lion OS) and used my time machine backup to restore my student version of MATLAB from my old mac (that ran Snow Leopard). That didn't work, so I tried reinstalling it from the website and that also didn't work. When I try to load MATLAB by clicking on the icon, a new MATLAB icon pops up and quickly turns into what's looks like a command prompt window and closes. And nothing happens after that... Can anyone tell me what I'm doing wrong? ...

The answer seems like it depends on several factors, but generally speaking which system is considered faster? Wondering if the two CPU Power4+ is equal or better in performance than one Power5 cpu. Yes, I plan to use multi-threaded applications. Yes, I know multi-threaded applications on a system with one CPU isn't ideal for performance. A) 7029-6c3 ( 2 way Power4+ running at 1.45ghz ) system uses DDR1 memory and 8MB of Level 3 cache vs B) 9111-520 ( 1 way power5 running at 1.65ghz ) system uses DDR1 memory-- no L3 cache. Thoughts?

Hi, I am designing a feedback control loop as part of a project. The MATLAB program reads data through the analog input of a DAC (NI USB 6009), and when there is enough data (say N), it starts to process the data to get a control output and send it through the digital output of the DAC. The reading should be kept going while processing the control signal; and the control signal calculation is refreshed when every time when N/3 data comes in (like a moving window of size N, averaging the old data with the new ones) My problem is how to perform these in parallel? This doesn't need to be in real time, but needs to be fairly quick, the delay still needs to be in orders of seconds. I am not sure if parallel computing toolbox is the solution or there are better (simpler) ways. I am new to Matlab, so please give me some advice on this ^^ thank u all. ...

The question comes from the following wikipedia entry http://en.wikipedia.org/wiki/Quicksort "Average complexity Even if pivots aren't chosen randomly, quicksort still requires only =C8(nlogn) time over all possible permutations of its input. Because this average is simply the sum of the times over all permutations of the input divided by n factorial, it's equivalent to choosing a random permutation of the input. When we do this, the pivot choices are essentially random, leading to an algorithm with the same running time as randomized quicksort. More precisely, the average number of comparisons over all permutations of the input sequence can be estimated accurately by solving the recurrence relation:" I don't see how they arrive at the recurrence relation. If there are n-1 comparisons, I thought it would be for i=3D0 to n-1 C(n) =3D 1/n * (sum(c(n - i - 1)) I don't get were the n-1 and C(i) terms come from. Can someone clarify this? Thank you. ...

Hi all, I am new to minix3. I admired its fast booting and design filosophy. I was searching for alternatives for my everyday developing and computing because I have the feeling that Linux is becoming more and more chaotic. So I installed minix3 and went ahead to measure its performance on scientific computing codes which are really numerically intesive codes. I tried to run a piece of code I wrote to test how minix3 would perform. This piece of code is one of the most basic kernels of numerical methods for solving large sparse systems of equations using iterative methods, and I use it from time to time for testing new OS. It performs a sparse matrix vector multiplication. This forum doesn't give me the opportunity to attach any files so I will just copy paste the code and the file I used. The minix3 performance was awful as it concerns the multiplication, part. The reading of the matrix was slighlty worse than that of Linux and this is affordable because the filesystems have different architecture. I compiled with: # gcc -O2 sparsematrixbench-minix.c -o run and then run the command: #./run matrix.txt 1000000 The last number is the number of iterations the mutliplication should be repeated. Below you can take a look at the results; the numbers represent milliseconds. multiplication Linux: 35 minix3: 1033 As you see the difference is dramatic. Moreover with a very large matrix of 20604953 bytes minix spits a memory fault e...

Hi! I am running a complicated measurement program acquiring data from a spectrometer, a photodetector and a webcam. I run Labview 7.1 on Windows 2000 Professional SP4 with 520 MB RAM (yes I know this is outdated, however the driver for the spectrometer does not run on XP and the product is obsolete). The problem is that I can run my program once without error and warnings and then the second time towards the end it freezes like it was in an endless loop, but there isn't any. I cannot quit Labview anymore and if I try to get to the task manager with ctrl-alt-del the screen just stays blue and I have to shut the computer off manually and reboot. This is very annoying because sometimes even some of the subVIs get corrupted. What is the best solution to debug it? In my case I guess there is no screen dump made since it actually does not crash but just becomes unresponsive. However is there a VI that would create a detailed LOG file about any strange things happening at the COM ports, GPIB bus e.t.c ? Thanks a lot for your help, I appreciate. David It is difficult to give advice without seeing the code, but here are a few things to look out for. Are you wiring all the error clusters?

I have a m-file script that I use to add some *.jar files to my dynamic java path. It then imports some classes and tries to use them. The first time I run my application when having just started Matlab, I get an error "Undefined function or variable 'MyClass' ". This error does not occur if I run my app any number of times later. Everything works perfectly when I close my GUI and simply run it again. I believe that this has to do with the asynchronous nature of Matlab and Java, but I don't know what to do so that my users will not have to run my app twice to get it to work. Any thoughts?

Hello dear People! For the very first time I have attempted to have BOTH Access 2000 AND Access 2002 installed on the same computer. I started with Access 2002 (XP). After I was sure the A2002 was running well, I installed Access 2000 from my original Office 2K Pro Microsoft disks with the only difference being that I told it to install on a different hard disk (D instead of C). It now appears that the A2k version is the DEFAULT version when ever I launch ANY MDB or MDE file. That's in itself is not a problem but what IS a problem is some startup behavior I have never seen from Access before: EVERY time I launch an Access app, Windows pops up a "must install this feature " box (or words to that effect. It does not prompt me for any disk inserts and it only takes about 5 seconds for this process to complete at which time it loads and runs the app normally. Any clues on how to fix this irritating little problem?
