I am running a code that uses up to 60% of CPU on my quad-core machine, suggesting that it is using some subkernel, introducing overhead in the computations and slowing down the program which is not optimized for parallel computing.
How do I check how many subkernels are currently running?
How do I tell Mathemtatica not to use any subkernel?
I use Mathematica 11.3 on a windows 10 64bit machine
LaunchKernels[]
or run someParallel*[]
functionality. You can see any subkernel processes from within Windows Task Manager. $\endgroup$ – ktm Nov 6 '18 at 16:06
