Error using parfoor: interactive sessions
显示 更早的评论
Hello guys,
please is it a good practice to have two parfor loops execute in the same function? For example, I have:
parfor slice_num = 1:number_of_labs
.
.
.
end
.
.
.
parfor slice_num = 1:number_of_labs
.
.
.
end
Now, my problem is that it generates an error stating: "Found an interactive session. You cannot have multiple interactive sessions open simultaneously. To terminate the existing session, use 'delete(gcp)'"
Please, you guys, what should I do to resolve this error?
Thank you for your assistant.

There shouldn't be any reason why you can't do this. I had a play around with my parallel preferences, but couldn't repeat your error. It should open a pool (if one isn't open and it is set to automatically open the pool) at the first parfor then it will keep this pool open for the length of time specified in your preferences and when you run the second parfor, if that first pool is still open it should just use it rather than trying to open another pool.

Were you originally calling parpool multiple times? That might give an error of that sort.

As Edric stated, I encountered the same error by calling parpool for the second time.

I had this error message when multiple defintion of parpool occurs, which is not allowed in Matlab.
