We went through a few options and our conclusion was: it didn't matter if we kept it in memory or loaded them each time it was executed as long as there was enough total memory on the machine to handle a service for each core. So we eventually opted for loading the mcr/service each time a job ran (yes with a 2 second delay of loading the mcr) because of simplicity. If we kept them running in memory we were still OK with the 200meg b/c the total memory was OK. fyi We run 8 cores with 2 gig per core on each machine. If I felt a job would run past the 2 gig I would utilize a memory mapped file in matlab. This way I had the stability of knowing I would never run out of memory. Just sharing our approach. We have been running for 4+ years now with very few issues. Stephen |
