In the master-worker model with
pmap, what is the correct way of checking for parallel vs. serial execution?
if nprocs() > 1 # do task in parallel else # fallback to serial execution end
if nprocs() > 2 # do task in parallel else # fallback to serial execution end
Can the master process perform work without overhead or I should add 1 for safety when querying
nprocs()? Assuming this is to be run on a HPC cluster without inter-node SSH communication.
