Installing Matlab
See Branden McKagen for details
Installing Matlab on Linux/UNIX
- This Section is under construction.
Installing Matlab on MAC OSX
Using the MPI parallel toolbox
The CVL lab has installed a toolbox that simplifies parallelizing matlab code. This is the location of the Matlab Parallelization Toolkit. It utilizes a Master/Slave arrangement to automatically login to multiple machines and have them individually run parts of a matlab script. The majority of the setup and configuration has been done on all of the CVL machines, but it is not in your matlab path by default.
- In order to access the MPI toolbox, you must manually add the directory '/software/MPI' to your path, either with the matlab path GUI, or with the command
addpath /software/MPI
- Once this is done, more information on how to operate the toolkit can be obtained by typing
help MPI from the matlab command window.
- The following is an example of how to implement the toolbox in matlab code
%This part defines how many nodes to try to use
%connects to available machines, and fires a Matlab slave node
addpath /software/MPI
%addpath /software/MPI_VAL32
%Read the config file set up for the cluster
mconfig = pconfig;
%Use all the machines available
Nparallel = length(mconfig);
%Run this many MATLAB processes per machine. This should be set to 1 to
%make resources available for others.
Nperhost = 1;
%Fire up matlab on the slaves. It may be worth using the load-checking
%version of psetup('available', Nparallel*Nperhost);
for j=1:Nparallel
psetup(mconfig{j}{1}, Nperhost);
end
%A example of a data set to chew on
a = rand(64, 64, 32);
res = zeros(size(a));
%Run a parallel profiler on the code to be run to see how much speedup there was (optional)
pprofile on -detail builtin
%The main parallel loop.
%It executes the function 'exampleloop.m'
pfor(1:size(a, 3), 'res(:, :, %d) = exampleloop(a(:, :, %d));');
%Finish the parallel profile stats collection
s = pprofile('report');
%Once the main computation is done, shut-down all the slave Matlab nodes
MPI_Finalize;
Here's a functional example of an 'exampleloop.m' matlab function
function out = exampleloop(in)
tempout = in
N=10000;
for i=1:N
tempout = inv(tempout) + rand(size(tempout));
end
out = tempout
One important point to note is that a portion of the MPI toolbox library must be compiled for the platform it's being run on. This has already been done for most of the CVL machines being run as 64-bit Linux. If the toolbox is to be used on a 32-bit Linux installation, a the MPI library will have to be installed into your home directory (or somehwere else you have write permission). It will also have to be added to your matlab path, and
makeMPI
must be issued from the matlab command prompt. The matlab installation must include mex, mcc, gcc, and g++ compiler properly installed.
