Dear R-Users, I run a MC-Simulation using the the packages "foreach" and "doMC" on a PowerMac with 24 cores. There are roughly a hundred parametersets and I parallelized the program in a way, that each core computes one of these parametersets completely.
The problem ist, that some parametersets take a lot longer to compute than others. After a while there are only a quarter of the cores still computing (their first parameterset), while others are already finished. But some parametersets are still untouched. I have thought about changing my parameterfile in a way, that every combination takes roughly the same time (longer computations are offset with less repetitions), but maybe there is a more elegant solution. "Is it somehow possible to wake the finished cores, while there is still work to do?" ;-) Sincerly, H.
