I tried starting parpool
in MATLAB 2015b
. Command as follows,
parpool('local',3);
This command should allocate 3 workers. Whereas I received an error stating failure to start parpool
. The error message as follows,
Error using parpool (line 94)
Failed to start a parallel pool. (For information in addition to
the causing error, validate the profile 'local' in the Cluster Profile
Manager.)
A similar query was posted in (https://nl.mathworks.com/matlabcentral/answers/196549-failed-to-start-a-parallel-pool-in-matlab2015a). I followed the same procedure, to validate the local profile as per the suggestions.
Using distcomp.feature( 'LocalUseMpiexec', false);
or distcomp.feature( 'LocalUseMpiexec', true)
in startup.m
didn't create any improvement. Also when attempting to validate local
profile still gives error message as follows,

I am receiving these error only in my cluster machine. But launching parpool
in my standalone PC is working perfectly. Is there a way to rectify this issue?
