Does anyone have experience using DL POLY with OpenMPI? I've gotten
it to compile, but when I run a simulation using mpirun with two dual-
processor machines, it runs a little *slower* than on one CPU on one
machine! Yet the program is running two instances on each node. Any
ideas? The test programs included with OpenMPI show that it is
running correctly across multiple nodes.
Sorry if this is a little off-topic, I wasn't able to find help on
the official DL POLY mailing list.
