All,
I've run across a somewhat difficult code for OpenMPI to handle
(CPMD).
Here is the report on the versions I tried:
1.1.4 - mostly does not start
1.1.5 - works
1.2.3 - does not start
The machine has dual Opterons, with Gigabit. The running command with
4x2 cpus is:
mpirun -np $np -machinefile $PBS_NODEFILE \
-mca coll self,basic,tuned -mca \
mpi_paffinity_alone 1 -mca coll_basic_crossover 4 \
$HOME/cpmd/cpmd.x_o $1 >> $2
Now, onto specific errors.
1.1.4 :
occasionally starts, occasionally gives the error:
PML add procs failed
--> Returned "Error" (-1) instead of "Success" (0)
--------------------------------------------------------------------------
*** An error occurred in MPI_Init
*** before MPI was initialized
*** MPI_ERRORS_ARE_FATAL (goodbye)
1.1.5 :
works fine
1.2.3 :
[node041:04866] pls:tm: failed to poll for a spawned proc, return
status = 17002
[node041:04866] [0,0,0] ORTE_ERROR_LOG: In errno in file rmgr_urm.c at
line 462
[node041:04866] mpirun: spawn failed with errno=-11
