Subject: [OMPI users] two problems with openmpi-1.9r28534
From: Siegmar Gross (Siegmar.Gross_at_[hidden])
Date: 2013-05-24 03:28:15


I installed openmpi-1.9r28534 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 I have two problems with this version.

sunpc1 hello_1 104 mpiexec -np 3 -host sunpc1,linpc1,rs0 hostname
[sunpc1:18681] [[19223,0],0] ORTE_ERROR_LOG: Data unpack had
  inadequate space in file
  at line 854

sunpc1 hello_1 105 which mpiexec
sunpc1 hello_1 106

My second problem is, that "rank_files" don't work as expected.

sunpc1 rankfiles 108 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").

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 problems. Thank you
very much for any help in advance.

Kind regards
