Extreme delays when creating parpool in newer releases
2 views (last 30 days)
I am trying to do some parallel processing and have run into issues when creating the worker pool. When I run the parpool command, even with only 1 worker specified, it will give the message "Starting parallel pool (parpool) using the 'local' profile ...", and then stall. I have waited a couple hours and it still does not complete the process or return an error. Interestingly, I have tried the same command on other versions of MATLAB installed on the same computer and was successful. I timed parpool(12) on the three versions I have and got the following results:
2017b: ~35 seconds
2018a: ~80 seconds
2020b: >2 hours
What could be causing this slow down, and how can I fix it?
