Hello,

I am attempting to run openmpi-1.0.2a12 on solaris opteron.
I compile in 64 bit mode, with Studio11 compilers

The configure and the make run fine.

I compile my application with :
mpicc -o myapp myapp.c

1/ I have the following hieroglyphs and error message when launching
mpirun :

icare> mpirun -np 4 -host icare ./myapp
T0<ú²þÿÿ+½T0<ú²þÿÿ4½T0<ú²þÿÿ=½T0<ú²þÿÿF½ld.so.1: myapp: fatal:
relocation error: file

The problem is fixed by compiling with -lrt option :
mpicc -lrt -o myapp myapp.c

2/ I attempted to force interface exclusion without success :

n14 > mpirun --mca btl_tcp_if_exclude bge1 -np 2 -host p14,p39 myapp
9ÿÿÿÿÿýD $ ½T Ö¡¸ÿÿÿÿý $ ½Process 0 is alive on n14
Process 1 is alive on n39
[n39:26824] *** An error occurred in MPI_Barrier

[n39:26824] *** MPI_ERR_INTERN: internal error
[n39:26824] *** MPI_ERRORS_ARE_FATAL (goodbye)

Best Regards,
Francoise
