comment Taskset not working over a range of cores in isolcpus
The kernel will not schedule a thread or process on the isolcpu unless the processor affinity mask indicates that it should be used. Otherwise isolcpus would be the same as turning the core off, when the purpose is to reserve a core for a user-specified reason and make sure no unwanted process uses it. Taskset sets the affinity mask to use all the cores in the 8-15 range (which is set correctly when checked in /proc) so the kernel should be scheduling the process on the idle cores.

comment Taskset not working over a range of cores in isolcpus
Yes, that's originally what caused me to notice (my multithreaded program wasn't using more than one core). A simple python script that creates a lot of threads fails to utilize more than one core when run on the isolcpus set. (When run on the non-isolated cores it utilizes all available 8 cores).
