Subject: [OMPI users] problem with rankfile in openmpi-1.7.2rc3r28550
From: Siegmar Gross (Siegmar.Gross_at_[hidden])
Date: 2013-05-24 03:16:52


I installed openmpi-1.7.2rc3r28550 on "openSuSE Linux 12.1", "Solaris 10
x86_64", and "Solaris 10 sparc" with "Sun C 5.12" in 32- and 64-bit
versions. Unfortunately "rank_files" don't work as expected.

sunpc1 rankfiles 109 more rf_ex_sunpc_linpc
# mpiexec -report-bindings -rf rf_ex_sunpc_linpc hostname

rank 0=linpc1 slot=0:0-1,1:0-1
rank 1=sunpc1 slot=0:0-1
rank 2=sunpc1 slot=1:0
rank 3=sunpc1 slot=1:1

sunpc1 rankfiles 110 mpiexec -report-bindings \
  -rf rf_ex_sunpc_linpc hostname
The rankfile that was used claimed that a host was either not
allocated or oversubscribed its slots. Please review your rank-slot
assignments and your host allocation to ensure a proper match. Also,
some systems may require using full hostnames, such as
"" (instead of just plain "host1").

  Host: linpc1
sunpc1 rankfiles 111

sunpc1 rankfiles 111 which mpiexec

I get the same error for my 64-bit version, but I don't have this
problem with openmpi-1.6.5a1r28554.

sunpc1 rankfiles 105 mpiexec -report-bindings \

I would be grateful, if somebody can fix the problem. Thank you
very much for any help in advance.

Kind regards
