Hello Prentice,
Thank you for your advice but that doesn't solve the problem.
The non-login bash updates properly the $LD_LIBRARY_PATH value.
Any other idea?
Thanks,

Hello,
I'm trying to understand the difference between theses two options:

and
" --bind-to-core "
To me, it's the same thing (may be paffinity have maffinity in
addition) but the purpose af theses options is to bind MPI process to

Hi,
Normally, that means a wrong path or incompatible compiler version, e.g.
32 bit vs 64 bit.

Ok, thank you for your answer. I think this rankfile feature is very
interesting to run some jobs like MPMD jobs or hybrid jobs
(multithreaded or GPU for examples).

Version: OMPI 1.3.3
Shell: bash
I already fixed the problem with a shell script like
#!/bin/sh
export LD_LIBRARY_PATH= ...
./montecarlo
But, it seems that openmpi look neither bash_profile not .bashrc.
Thank you,

Doesn't that indicate precisely what Prentice said? ssh isn't picking up your
remote .bashrc file and executing it.
Try just doing "mpirun -n 1 -H hpcnode1 printenv" and see if you get the envars
you expect from you .bashrc. If not, talk to your sysadmin about how to fix the
problem - could be

Hello,
I am building a cluster with 6 Apple xserve running OSX Server 10.6 :
node1.cluster
node2.cluster
node3.cluster
node4.cluster
node5.cluster
node6.cluster
I've intalled openmpi in directory /opt/openmpi-1.4.2 of node1 then I made a
share point of /opt -> /Network/opt and define variables
For the benefit of anyone else trying to build with it on x86_64
GNU/Linux (or, presumably, i386): Sunstudio 12, update 1 loops while
compiling 1.4.2's btl_sm.c with configure's default flags. Sun patch
141859-04 fixes that.
Did "--mca mpi_preconnect_all 1" work?
I also face this problem "readv failed: connection time out" in the production
environment, and our engineer has reproduced this scenario at 20 nodes with
gigabye ethernet and limit one ethernet speed to 2MB/s, then a MPI_Isend &&
MPI_Recv ring that mea

Interesting. If I add the Fortran compiler as a new entry through the
GUI, CMake wipes it. If I use the option to specify the compiler paths
manually on Configure, I can add the Fortran compiler in that way and it
works.
Then there's a compiler error. In

Hi Damien,
That's a known problem. see this ticket

1.5 branch very soon. But if you apply the patch by yourself, it should
also work.
