Re: [OMPI users] problems with hostfile when doing MPMD

I believe this -should- work, but can't verify it myself. The most important thing is to be sure you built with --enable-heterogeneous or else it will definitely fail. Ralph On 4/10/08 7:17 AM, "Rolf Vandevaart" wrote: > > On a CentOS Linux box, I see the following:

Re: [OMPI users] problems with hostfile when doing MPMD

Hi Jody Simple answer - the 1.2.x series does not support multiple hostfiles. I believe you will find that documented in the FAQ section. What you have to do here is have -one- hostfile that includes all the hosts, and then -host each app-context to indicate which of those hosts are to be used

Re: [OMPI users] problems with hostfile when doing MPMD

Rolf, I was able to run hostname on the two noes that way, and also a simplified version of my testprogram (without a barrier) works. Only MPI_Barrier shows bad behaviour. Do you know what this message means? [aim-plankton][0,1,2][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_complete_connect]

Re: [OMPI users] problems with hostfile when doing MPMD

This worked for me although I am not sure how extensive our 32/64 interoperability support is. I tested on Solaris using the TCP interconnect and a 1.2.5 version of Open MPI. Also, we configure with the --enable-heterogeneous flag which may make a difference here. Also this did not work

Hi Using a more realistic application than a simple "Hello, world" even the --host version doesn't work correctly Called this way mpirun -np 3 --host aim-plankton ./QHGLauncher --read-config=pureveg_new.cfg -o output.txt : -np 3 --host aim-fanta4 ./QHGLauncher_64 --read-config=pureveg_new.cfg -o

[OMPI users] problems with hostfile when doing MPMD

HI In my network i have some 32 bit machines and some 64 bit machines. With --host i successfully call my application: mpirun -np 3 --host aim-plankton -x DISPLAY ./run_gdb.sh ./MPITest : -np 3 --host aim-fanta4 -x DISPLAY ./run_gdb.sh ./MPITest64 (MPITest64 has the same code as MPITest, but was
