Hi Jeff,
Before I go any further with this...
I am trying to run LAM across a network, one machine an Intel 32-bit, with
LAM-7.1.1 installed. Another machine is an AMD 64-bit, with 64-bit LAM-7.1.1
installed. I have tried running MPI apps across the 2 machines, on a
properly lambooted LAM universe. Everything seems to run fine.
And I have checked that the mpicc has -laio, from "mpicc -showme", in fact,
it is in there twice:
/opt/SUNWspro/bin/cc -I/home/fjcsuper/lamMpi/include -mt -lthread -L/home/fjcsuper/lamMpi/lib
-llamm
pio -llamf77mpi -lmpi -llam -laio -laio -lsocket -lnsl -lthread -lthread -ldl
Anything else I need to make sure I have done right? Seems stuck now...
Thanks for your time.
Regards,
Juncheng
