Hello Everybody,
I am planning to buy sixteen AMD64 Athlon dual core machines (with
Linux) for running G03 in parallel. They will be connected by ethernet.
I never have any experience in running gaussian with Linux cluster. So
my questions are the following:
1. Can G03 be run parallel in the above configuration?
2. Do you need to have Linda for running parallel in the above
configuration?
You need Linda to run G03 in parallel.
The OpenMP parallelization should also work without Linda - but of course
limited to some routines and 2 cores.
I was unaware of a "2 core" limit. Are you sure that you cannot
run Gaussian on four cores in a dual-cpu dual-core SMP configuration?
(assuming compiled from source on Linux)
