Hi, I have a matlab 2007b installed on my machine which has Distributed computing toolbox v3.2 installed. my questions are? 1. will i be able to do parallel computing using this versions of matlab including DCT? 2. I tried serchign for jobmanager but could not trace it. Do i have to install Parallel computing toolbox, seperately? I just could not proceed with my existing installations. What next should i do? All info above is required so that i could run two parallel optimizations originationg starting somewhere in between my original code. The original code does some input calculations. These values are then required for optimizations. However currently i run the optimizations sequentially one after the other> TO improve on the speed i am looking forward to run the two optimizations parallely. How do i do that? My current machine configurations are: Pentium 4 - 2,8Ghz, 1GB Ram. Is this suffucient? Also i may not be able to connect to another machine or server, will this still do the parallel or i have to connect elsewhere for optimium benefits? Please advice... Thanks in advance. Satish

HI, I have an optimization code which has some part code is common and required as inputs for the two optimization routines within. However once this is done, the remaining could be run parallely independednt of each other and imrovized on the speed and finally the two results could be fetched in one single main optimization file and compared. Though i feel this could be done, i do not knopw the exact procedure as well do not know if there is some setting to be done in matlab and modify my main code as well. Please note i have matlab 2007b and distributed computing toolbox v3.2. I...

I'm running R2008B on a 2 PC cluster (XP Pro). Each PC has four cores. I've confirmed that the Matlab distributed computing toolboox and parallel computing toolbox are properly installed and running on both machines. 4 green checks appear when I validate through the configuration manager. Max number of workers set to 16. My question: I want to confirm that when I run a job all 4 cores on each machine are utilized for a total of 8 cores. My error when I try to open a pool with 8 cores is below. Is there another command I should try? Thanks. >> matlabpool open 8 Starti...

Hi, there, Is there some way that can use the parallel computing code such as parfor or spmd in the distributed computing server? I currently ran a test for comparing the difference between the parallel toolbox with in stand alone mode in a computer with two CPUs, and the distributed computing server in two computers(each of them using just one CPU). I found the computing capabilities are pretty much the same with each other. I was curious how to run a parallel computing in the distributed server. Thanks, Wei Wei, The Parallel Computing Toolbox (PCT) serves two purposes: leverage...

I would like to know how Distributed Computing Server assigns tasks to computers, especially when running parfor loops. 1. Is the computer the main program is running on used as one of the clients? Or are all tasks (parfor loop iterations) executed on other computers? What happens if there are two tasks and three computers: PC 0 main program task 1 PC 0 main program PC 1 task 2 PC 1 task 1 PC 2 no task PC 2 task 2 What happens when there two computers: PC 0 main program task1 PC 0 main program, no task PC 1 task 2 ...

Hi, Is it true that the parallel computing toolbox won't work if the distributive computing toolbox has not been installed? Because then if I type in 'matlabpool', I received the following err msg: " License checkout failed. License Manager Error -4 Maximum number of users for Distrib_Computing_Toolbox reached.

We have several linux workstation and each of them has matlab installed on it. They share the same data file system (NFS). Unfortunately we do not have the distributed computing toolbox and the management is not planning to buy it. So I am trying to find a workaround to use the workstations in parallel for my computation. I could think of 3 ideas, and I'd like to get some suggestions and comments from the community. 1) execute matlab via ssh: ssh user@host 'matlab -nodisplay -r "myfun(1,2,3)" '. This would require a script to handle the different connections and feed...

[Responding to David C. DiNucci's post from October 1, 2005] Hi David. I hope to follow up in full on your last message shortly. There's a lot to read (a good thing)! I will try to discuss a couple things in more depth The usefullness of modelling global states - how they relate to: - adversaries - levels of network awareness: does each process know how many other processors are collaborating? Is the number of processors fixed or varying? Is the network fixed or dynamic? Do the processors have any 'sense' of direction' in the network? Distributed knowl...

Hello All, I want to achieve communication between MATLAB(and simulink) installed on one computer with the MATLAB(and simulink) installed on another computer. the communication requires that the local copy of matlab performs some calculations, taking into account data from MATLAB on a different computer, and the results are available to the other computer's Matlab as well, and vice versa as well. The two computers are connected through LAN. Thank you, Sunny "sunny " <supersunny007@yahoo.co.in> wrote in message <fv6pn2$j6c$1@fred.mathwor...

I have the parallel computing toolbox, but not the distributed computing server. Is it possible to run distributed jobs on a local network cluster from programs written with the parallel toolbox without the distributed server? Or is the server more than just a scheduler; e.g. does it serve as Matlab's alternative to MPI in addition to actually scheduling the jobs? Thanks!

Hi I like to use parallel threads, to use the multiple processor cores. (I have a quadcore system and frankly when using matlab despite all mathworks claims I NEVER EVER spotted it using more than 1 core (i.e. 25% CPU usage!) - yes I enabled multithreading support in the preferences). Anyway. So I want to take things in my own hands. So I started with and example of an "embarresingly parallel task: filtering 12 images. The images are in the variable imgs{...} tic I={}; h = fspecial('gaussian',30,30); for jj= 1:size(imgs,2) I{jj}=imfilter(imgs{jj},h); end toc -> this takes...

Hello, I would like to know if it is possible to run multiple m-files parallelly in MATLAB. For example, suppose I need to run 'n' script files all independent of each other. I needed it for a robotics application. Is it possible to assign preferences to the processes(like in real time processes) so that a process of lesser preference is put on the hold if a more preferred task needs to be run.

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.
