Im using the Matpower – Matlab toolbox in parallel computing and building the computer cluster to simulate the programme which is shown below:
matlabpool open job1 5 % matlabpool means computer cluster
spmd %the statement from the Parallel computing toolbox% Run all the statements in parallel% first part of codeif labindex==1runopf('casea');end% second part of codeif labindex==2runopf('caseb');endendmatlabpool close;
When the labindex is 1 the first part of code in this program is running in "computer1" in the cluster, and so forth when the labindex is 2, then the second part of code in the program is "running in computer2". My question is the main code shown above running in sequence or in parallel?
By which I mean, does the second part code has to wait to be executed until the first part of code is executed or two parts of codes can be executed parallel at the two different computers in the cluster?
