I have a very simple test that I run after installing an MPI
implementation. This program installs a handler on signal SIGUSR1. The
handler from rank=0 sends a message (MPI_Issend) to rank=1 and from
rank=1 it sends a message to rank=0. The main routine of the program is
normally pending on MPI_Recv.
This program uses to work under MPICH 0.93, but on LAM 6.5.9 the
MPI_Recv seems to hang after receiving the very first message.
Did I select the wrong LAM version or the above is simply a not
supported scenario?
Thanks,
Rodrigo
ps: my LAM 6.5.9 configuration was this (redhat 7.2, gcc = 2.96)
./configure --with-threads --enable-shared=yes --without-mpi2cpp
--without-fc --without-romio --prefix=/export/data/ramestic/alma/lam |
tee c.log
