hi, everyone: I have a problem about the paralle computing when using parallel computing box. I want to combine the matlab with the HFSS to solve a problem, but I find it can't work when i call the HFSS in one cluster. The program belows: >jm=findResource('scheduler','type','jobmanager','name','isaac','LookupURL','192.168.58.109'); >job=createJob(jm); >set(job,'PathDependencies',{'Y:\'}); >createTask(job,@vbs,1,{2}); >submit(job); >waitForState(job); >results=getAllOutputArguments(job) >destroy(job); >function a=vbs(i) >hfssExecuteScript('C:\"Program Files"\Ansoft\HFSS10\hfss.exe','Y:\pipi.vbs',false,true); >i=i-1; >a=i; When i run this program, the HFSS would open, but never open the pipi.vbs ,why ? where is the problem??? just help me ,thank you !!

I think the problem is that you're using the jobmanager and trying to access "pipi.vbs" using a mapped drive-letter. MDCS workers can't see your drive letter mappings. It should work if you provide a UNC path such as \\server-name\path\to\pipi.vbs (We have an undocumented function that can do this mapping for you, dctReplaceDriveWithUNCPath('y:\pipi.vbs') that you must run on your MATLAB client (not on the cluster) - but please be aware of the usual caveats about undocumented stuff - we might choose to remove/change/rename it without notice) Cheers, Edric.

I hope you can help me, i am tired about this. thank you again.

I am sorry about the reply to your answer. you are right:"MDCS workers can't see your drive letter mappings. It should work if you provide a UNC path". and now i have solve this problem ,thank you Edric,my friend.

first,thank you for your answer. Now I want to start a worker on a remote claster,and on that claster i want to start the hfss, how to do that ?? I use the UNC path,but how to define the path of the hfss.exe?? >hfssExecuteScript('C:\"Program Files"\Ansoft\HFSS10\hfss.exe','\\Isaac\ceshi\pipi.vbs',false,true);

Hi all, I need your help. I have a Matlab program, which uses the Matlab symbolic toolbox and does exclusively symbolic computations. It calls Maple's library internally. My program is currently non-parallel. I need to run it on a super computer. The super computer does not have Matlab and it is Linux based and supports MPI. I didn't figure out how to convert non-parallel program into parallel exectuables on Linux with MPI. Since I failed to get a nice solution of the above problem, now I am willing to make a comprise, I am going to make it coarse-grained distrubuted computing: (1...

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...

The “divide and average” method, an old-time method for approximating the square root of any positive number "a" can be formulated as: x= (x+a/x)/2 (a) Write a well-structured pseudocode to implement this algorithm. Use proper indentation so that the structure is clear. (b) Develop, debug, and document a Matlab function to implement this equation. Its basically a problem that by using this formula or function it would give me the square root of a number inserted. I see you cut the (!) down from 22 to 1. That is a good start. Now, where are you stuck? _U...

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. Please give details, as I am not very used to MATLAB. Thanks in advance. Regards... "ajay " <ajaypai88@gmail.com> writes: > I would like to know if it is possible to run mu...
