Subject: Re: [OMPI users] problems with rankfile in openmpi-1.9a1r29097

It seems to run for me on CentOS, though I note that rank 0 isn't bound to both sockets 0 and 1 as specified and I had to tell it how many procs to run:

[rhc_at_bend001 svn-trunk]$ mpirun --report-bindings -rf rf -n 4 hostname
[bend001:13297] MCW rank 0 bound to socket 0[core 0[hwt 0-1]], socket 0[core 1[hwt 0-1]]: [BB/BB/../../../..][../../../../../..]
bend001
[bend002:25899] MCW rank 3 bound to socket 1[core 7[hwt 0-1]]: [../../../../../..][../BB/../../../..]
bend002
[bend002:25899] MCW rank 1 bound to socket 0[core 0[hwt 0-1]], socket 0[core 1[hwt 0-1]]: [BB/BB/../../../..][../../../../../..]
bend002
[bend002:25899] MCW rank 2 bound to socket 1[core 6[hwt 0-1]]: [../../../../../..][BB/../../../../..]
bend002

[rhc_at_bend001 svn-trunk]$ cat rf
rank 0=bend001 slot=0:0-1,1:0-1
rank 1=bend002 slot=0:0-1
rank 2=bend002 slot=1:0
rank 3=bend002 slot=1:1

I'll work on those issues, but don't know why you are getting this "not allocated" error.
