Subject: [OMPI users] "bind-to l3chace" with r30643 in ticket #4240 dosen't work

Hi Ralph,

Since the ticket #4240 has been already set as fixed, I'm sending this
email to you. ( I don't konw I could add comments to the fixed ticket)

When I tried to bind the process to l3chace, it didn't work like below:
(the host mangae has the normal topology - not inverted)

[mishima_at_manage openmpi-1.7.4]$ mpirun -np 2 -bind-to l3cache
-report-bindings ~/mis/openmpi/demos/myprog
--------------------------------------------------------------------------
No objects of the specified type were found on at least one node:

  Type: Cache
  Node: manage

The map cannot be done as specified.
--------------------------------------------------------------------------

"-bind-to l1cache/l2cahce" doesn't work as well. At least, I confirmed that
the openmpi-1.7.4 works with "-bind-to l3cache".

Regards,
Tetsuya Mishima
