I wonder if this is only true if you, for instance, compile gaussian with a PGI demo license or something. also, the normal (old) way of using SMP is fork-based parallelism with SYSV shm. is this separate (orthogonal) to OpenMP-based parallelism? I suspect the latter is only used for SMP parallelism within parallelized blas libraries like MKL. > machines with single dual-core CPUs. Let's rephrase: ...but limited to the > cores in each of the machines. mosix, I believe, provides network-shared SYSV shm. I wonder if anyone has tried to use gaussian that way. depending on the sharing patters, it might work pretty well - my understanding is that the shm is used mainly for caching intermediate values (integrals?), which might be write-once-read-mostly, and therefore friendly to the kind of caching necessary for any page-based net-shm implementation. regards, mark hahn. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
