Hi,
I'm running Mathematica 12.0 with a license for 8 kernels. Recently when I run a parallel process (typically with Method->"CoarsestGrained") only 4 of the kernels (sometimes less) are being used when it is clear that much more than half the tasks are left. In the past all 8 would be active. What is going on and how can I get all 8 kernels to be used?
Thank you, Troy Wahl
Hi Troy,
Have you checked the configuration settings as described in this support article? What does the following evaluate to?
Parallelize[Map[{#, $KernelID} &, Range[12]], Method -> "CoarsestGrained"]
