Hello My Matlab version is R2010a 64bit Linux. I can see that my Matlab comes with parallel toolbox. However, in that toolbox, I can not find GPU computing subsection. Matlab therefore gives error when I call "gpuArray". I wonder why is that, is that because my Matlab Version is old, or do I have to purchase a separate gpu toolbox?

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.

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 ...

Dear all, I am currently using parallel computing for optimization. I use "matlabpool open 8" command; and use Multistart function for the optimization. In the Multistart function it has been set to be "UseParallel" is "always". Problem is that I see 9 MATLAB image name in Window task manager. Only one of them use 25% of my CPU resource (I have a quad core computer; 25% is equal to one core is fully operating) . All others are 0% CPU usage. I really don't understand the situation. In term of memory usage, the one using 25% of CPU power use 210M bytes. All the others uses 109M bytes. In my computer, open a new MATLAB window but doing nothing is around 109M bytes. What that means?? Please help. I need the parallel computing power. Thanks ...

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. ...

I have a quad core computer; and I use the parallel computing toolbox. I modify the default 'local' setting; and set different number for the "worker" number in the parallel computing setting, for example 2,4,8.. And also set the minimum and maximum worker to work for the task. After the setting, I did the validation to make sure everything is ok. However, no matter what I set, the AVERAGE cpu usage by MATLAB is exactly 25% of total CPU usage; and None of the cores run at 100% (All are around 10%-30%). I am using MATLAB to run optimization problem, so I really want my quad core computer using all its power to do the computing. Please help ...

Good day all, I currently have an optimization algorithm implemented in Matlab. The time to arrive at a solution for this algorithm varies. There is a speed variation since success of ending the optimization relies on randomly selecting a set of data which is hopefully reliable enough for a solution. So for example, my algorithm can end in little as 1 iterations or a maximum of 200 iterations ( i.e. ,a value which I set). I have seen Matlab's Parallel computing toolbox but not sure if would apply to my situation. I would like to know if it is possible to somehow run my algorithm in "parallel" jobs, such that, I can run the script multiple times and end the overall algorithm with the job that terminates first ? Is anything like this or similarly possible with the parallel toolbox? thanks any suggestions, Aiden "Aidy" wrote in message <j7i8jp$1ai$1@newscl01ah.mathworks.com>... > Good day all, > > I currently have an optimization algorithm implemented in Matlab.

I have a x86-64 system w/ 12 Cores and 8 GPU cards. Supposing I have the parallel toolbox, I am allowed to use up to 12 workers. From what I understand, the following scenario would work (Please correct me if I'm wrong): assign N workers to N GPU cards and (12-N) workers to (12-N) cores. Now, are we allowed to assign multiple cores to a single worker, and have that worker multi thread between cores? For example, use 5 workers: 4 workers to 4 GPU cards, and 1 Worker for 6 cores? I would appreciate any help. ...

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.

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.

For the question below i was looking for help since some parts of it i don't get. For part A I import the data in matlab and then plot it using the plot function. i get my x-axis as the number of samples which is 16384 and then the y is the values of the signal. but i dono if i am drawing it correct. should it be in any diff format in terms of x-axis. maybe freq? For part B i found the Fs by deviding the 80ms/16384. Which should b right. For part C i get the dc componmet which is the mean of the graph from matlab. although if my FFT graph is corrct in the next part the X(0) will be my dc componemet. For part D i use FFT(ABS(signal)) get a real values but i need to confir this. Can you please tell me what i should do here? and show me the steps ONE BY ONE in matlab. i will need full answers and not walkthorughs since i have an idea how to do it but i know it is not right. files or graphs can be sent using www.yousentit.com or a link. the signal file can be found here: http://s59.yousendit.com/d.aspx?id=2QOB20YI5KNOG262E4UMLJAH8J thanx a bunch in advance. i am so lost in this one :( Question: The attached file called �signal� is a list of 16384 real numbers.

greeting all, i'm using nonlcon(nonlinear inequality constraint) with GA from the toolbox provided by matlab. does anyone notice the extreme slowlness in evaluating nonlinear constraint as compared to other linear constraint? my problem for nonlinear constraint is as follow c(1)=x+y^2-2*ones(N,1) where x and y are Nx1 vector. which means if N increases, the size of constraint increases. and to clarify, the min problem is sometime like min c'z where z=[x;y], which means x and y are some range of variable within z(just a matter of problem formulation) well, is there anyone with other alternative or is it possible or method in including non-linear constraint directly to fitness function? (well, actually nonlcon deals nonlinear constraint by using Augmented Lagrangian Pattern Search from what i see from the help file, or am i wrong?) and one more question, is there anyone that attempt to attempt to apply mixed integer problem into the GA in matlab? For now, i can only switch before pure integer or pure real number problem, but not mixed at the moment. I will be trying to add in some repair operator to fix up the variable that needs to be integer and other remaining in real number. I'm not sure why you are using ga to solve your problem. Did you find fmincon unsatisfactory in any way?

1. Sometimes, we do parallel computing in Matlab. If we write parallel code but run it without opening workers, will we lose efficiency? I mean that compared to non-parallel code, will it run much slower? 2. Does all random number generators (for example, random number generator for normal distribution, random number generator for uniform distribution, and so on) in Matlab share a same basic random number generator? 3. When we do parallel computing in Matlab, will the random number generators be synced? For example, if we use a paralleled loop, will the random number generator be locked if it's being used by a thread, so that it cannot be accessed by other threads? 4. I wrote some parallel code in Matlab. Sometimes it runs OK but sometime error happens. I used a random number generator "normrnd" in my code. If I change this function to "randn" then it always works. Does anyone know the reason behind this? Why does "normrnd" lead the parallel computing to failure sometimes? It depends on the task, your system and your code. Are you using parfor or spmd blocks? Some sample code would go a long way in helping figure it out. One thing I will suggest is to open a matlab pool session and run pmode. This opens an interactive parallel job, so you can see what is happening on each worker as you run the code.

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.
