Dear all,
I am playing with Open MPI 1.7.5 and with the "--map-by" option but I am not
sure I am doing thing correctly despite I am following the instruction. Here
what I got
$mpirun -np 20 --npersocket 5 -bind-to core osu_alltoall
--------------------------------------------------------------------------
The following command line options and corresponding MCA parameter have
been deprecated and replaced as follows:
Command line options:
Deprecated: --npersocket, -npersocket
Replacement: --map-by socket:PPR=N
Equivalent MCA parameter:
Deprecated: rmaps_base_n_persocket, rmaps_ppr_n_persocket
Replacement: rmaps_base_mapping_policy=socket:PPR=N
The deprecated forms *will* disappear in a future version of Open MPI.
Please update to the new syntax.
--------------------------------------------------------------------------
after changing according to the instructions I see
$ mpirun -np 24 --map-by socket:PPR=5 -bind-to core osu_alltoall
--------------------------------------------------------------------------
The mapping request contains an unrecognized modifier:
Request: socket:PPR=5
Please check your request and try again.

[tesla49:30459] [[29390,0],0] ORTE_ERROR_LOG: Bad parameter in file
ess_hnp_module.c at line 510
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
orte_rmaps_base_open failed
--> Returned value Bad parameter (-5) instead of ORTE_SUCCESS
--------------------------------------------------------------------------
Is there any place where the new syntax is explained?
Thanks in advance
