Parallel pool shut down due to error?
显示 更早的评论
I'm trying to execute a code using 12 parallel workers with parfor in Matlab-r2014b. I am allowed to do it since the machine I'm using has 12 cores.
However when I start running the code, after 10-15 minutes, the symbol on the bottom left of the Matlab screen [next to the word "Busy"] (which is usually a blue or green rectangle when parfor is properly working) becomes grey with a yellow triangle. If I pass the mouse over it I get a message saying "Parallel pool shut down due to error". The Matlab command window does not report any error and the code keeps working I guess using just one worker.
Any idea of the possible causes of the message?

Minimal working example of the code?

If the pool shut down in this way, that usually indicates a crash on one of the workers.
