Matlab workers represent threads used by Matlab (or the MCR libraries when using the Dynamo standalone) when a computation is launched in parallel modus on a single node. A parallel computation in Dynamo should not use more matlab workers than the number of physical cores available in your system.
Find out the number of cores in a system
In Linux
In the system terminal, write:
cat /proc/cpuinfo | egrep "core id|physical id" | tr -d "\n" | sed s/physical/\\nphysical/g | grep -v ^$ | sort | uniq | wc -l
In the Mac
In the system terminal, write:
sysctl -a | grep machdep.cpu | grep core_count
sysctl -a | grep machdep.cpu | grep thread_count
