Hi,
there appears to be a regression in revision 1.5.2rc3r24441.
The attached program crashes even with 1 PE with:
Default real, digits: 4 24
Real kind,digits: 8 53
Integer kind, bits: 8 64
Default Integer :

Error means OMPI didn't find a network interface - do you have your networks
turned off? Sometimes people travel with Airport turned off. If you haven wire
connected, then no interfaces exist.

Hi all,
I am having trouble with PGI on Mac OS X 10.6.6. PGI's support staff has
informed me that PGI does not "support 64-bit shared library creation"
on the Mac. Therefore, I have built Open MPI in static only mode
(--disable-shared --enable-static).
I have to do some manipulation to get m

I have not had the time to look into the performance problem yet, and probably
won't for a little while. Can you send me a small program that illustrates the
performance problem, and I'll file a bug so we don't lose track of it.
Thanks,

Yes, you will have problems.
We did not formally introduce ABI compatibility until version 1.3.2. Meaning:
your application compiled with 1.3.2 will successfully link/run against any
1.3.x version >= 1.3.2, and against any 1.4.x version.
v1.5 broke ABI with the v1.3/v1.4 series, but it will al

Certainly you may call MPI functions many times, the problem is that you
need to have matching receives (or collectives) at your slave nodes, which
is only determined at run-time. Perhaps this could be done with two
communications, the first broadcast the type of communications to the slaves

I thought you mentioned in a prior email that you had gotten one or two other
OFED sample applications to work properly. How are they setting the SL? Are
they not using the RDMA CM?

So, since RoCE has no SM, and setting an SL is required to get
lossless ethernet on Cisco switches (and possibly others), does this
mean that RoCE will never work correctly with OpenMPI on Cisco
hardware?
