I had linpack running just fine with MPICH. When I switched to LAM/MPI and recompiled linpack, it thinks that there is only one node online. I've traced it down to the MPI_Size function. My own programs run fine. But apparently, the MPI_Size function in linpack is returning 1. I'm going to post this message on the linpack mailing list, assuming there is one, but if anybody here knows whats going on, help would be much appreciated. At this point, I'm not sure if its a linpack or LAM/MPI problem.
