Parallel computing #19

Hello friends,

         I am implementing HMM based speech recognition system on MATLAB-2009a. I am trying to design system such a way that , in GUI recording of speech from user and computation for HMM for earlier speech going together in parallel . Right now I am using wavrecord(n,Fs) function to record speech. But it can't support parallel computation like , waiting for speech while other calculation is going on.

         Please give some suggestion for this problem or other audio recording function which works as I want......

Thanks,

parallel computing on a six-core local computer
Hi, I just bought a six-core desktop (12 Threads) and discovered that the maximum worker allowed by the parallel computing toolbox is eight workers. This is really disappointing, and I am just wondering if there is anyway to fully utilize the 12 processes and have 12 workers on one local machine. I browsed the help guide for the Distributed Computing Server toolbox and it seems it only works when you'd like to create workers on remote computers. Your help is greatly appreciated. Thank you! richard "Richard Liu" <richardkailiu@gmail.com> wrote in message news:hrhupd$2v3$1@fred.mathworks.com... > Hi, I just bought a six-core desktop (12 Threads) and discovered that the > maximum worker allowed by the parallel computing toolbox is eight workers. I believe that is the correct behavior, assuming you have just Parallel Computing Toolbox. To use more than 8 local workers, or to use workers across multiple machines, you will need MATLAB Distributed Computing Server as well. > This is really disappointing, and I am just wondering if there is anyway > to fully utilize the 12 processes and have 12 workers on one local > machine.

FAQ 4.43 How do I compute the difference of two arrays? How do I compute the intersection of two arrays? #19
This is an excerpt from the latest version perlfaq4.pod, which comes with the standard Perl distribution. These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 4.43: How do I compute the difference of two arrays? How do I compute the intersection of two arrays? Use a hash. Here's code to do both and more. It assumes that each element is unique in a given array: @union = @intersection = @difference = (); %count = (); foreach $element (@array1, @array2) { $count{$element}++ } foreach $element (keys %count) { push @union, $element; push @{ $count{$element} > 1 ? \@intersection : \@difference }, $element; } Note that this is the *symmetric difference*, that is, all elements in either A or in B but not in both. Think of it as an xor operation. -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.

Applications of parallel computing
Hi all, I'm working on a project that involves parallel computing, and I'm trying to think of applications that would benefit from parallel computing. For example, in cubic spline interpolation, I can divide the interval into groups that can each be handled by a processor. However, that simply provides an embarrassingly parallel solution. I would like to know if there are any problems that will benefit from parallel computing, for example problems that are computationally intensive. I'll be using MPI to program the parallel solutions. Thank you. Regards, Rayne [Moderator: see the Grand Challenge panel which should be auto posted in a few more days.] -- ...

Help with Parallel Matlab
Long story short, here is the criteria I need. 1) I need two modules running in parallel. One function must activate these two They don't need to START at the same time but both neither return info nor end. They run pretty much infinitely 1.1) I would prefer if the One function also ran separate from the above two in it's own loop but i can deal with a 3'rd function also not ending. 2) I need a shared variable between two of the modules. 1 Module will place information there while the other just reads it, but as they are running parallel. That's it. I can do this in pretty much any other language but matlab I've been having issues with. Problem is I absolutely need to use matlab for one module. If this is impossible to accomplish all in matlab then can i instead run this in C and call one matlab module with separate thread? Sample code below. function mainParallelTest() persistent counter; counter = 0; parfor i=0:2 if (i == 0) ImageProccessorParallelTest(); elseif(i == 1) EventProcessorParallelTest(); elseif(i == 2) prevCounter = 0; tempCounter = 1; while(true) tempCounter = counter; if (tempCounter == prevCounter) %disp('hi') end prevCounter = tempCounter; end end end "Alex Cruikshank" <cruiksam@gmail.com> writes: > Long story short, here is the criteria I need. >...

Matlab Compiling and Parallel Running
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 ...

[9fans] parallel/distributed computation
Hi all, As I'm working in a geophysics lab, one of my point of interests regarding plan9 would be heavy scientific computation, especially parallel computing. So, first is there any fortran compiler on plan9? Second, is there any support for parallel computing, like mpi (even libs for that in C would be something)?

You have two choices. 1) write it from scratch 2) port gcc and then all of gnubin -- and then all of the various parallel computing software if you want industrial strength versions of this type of thing, you won't do (1) better than the scads of people doing it now (well, your code will sure look better than openmpi.org, but it won't do mpi better). So you might want to start with the gcc port. Not because we want gcc, mind, but because we need gcc -- because there are way too many bits that have to be done, and not enough people to do them. ron ...

Parallel Computing: clustering workers
I have a computation problem which can be divided into a part that can be performed on GPU's and a part that needs to be run on a CPU. The first part (GPU side) can be divided up between many GPU's to speed computation, but the CPU side has to be single threaded and processes the result from the GPU part. So right now, the current flow of my code looks something like: GPU \ GPU ---- (gather)----> cpu -----> result GPU / With this layout, the cpu sits idle while the GPU's work, then the GPU's sit idle while the CPU works. I would like to set this up such that once the GPU (running on a number of workers) finishes, it gathers the data, submits a new job to the scheduler to begin the CPU processing, then starts over on the GPU processing so that both sides can run at the same time. Is there a way to either submit a task to just one worker, or otherwise segregate the workers like this?

MATLAB will not run on new computer...
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...
