Re: [OMPI users] libmpi_cxx

You need to configure with --enable-mpi-cxx -- the Open MPI C++ bindings are not built by default. Can I ask what software you are using that requires the MPI C++ bindings? I ask because the MPI C++ bindings were deprecated in the MPI-2.2 standard in 2009, and were formally deleted from the

Re: [OMPI users] Old version openmpi 1.2 support infiniband?

That's actually failing in a shared memory section of the code. But to answer your question, yes, Open MPI 1.2 did have IB support. That being said, I have no idea what would cause this shared memory segv -- it's quite possible that it's simple bit rot (i.e., v1.2.9 was released 9 years ago --

(Sending this to the users list, not to just the owner of the users list) It looks like you might have installed Open MPI correctly. But you have to give some command line options to mpirun to tell it what to do -- you're basically getting an error saying "you didn't tell me what to do, so I

Re: [MTT users] MTT username/password and report upload

Yes, it's trivial to reset the Fujitsu MTT password -- I'll send you a mail off-list with the new password. If you're just starting up with MTT, you might want to use the Python client, instead. That's where 95% of ongoing development is occurring. If all goes well, I plan to sit down with

Oops; it looks like there's 2 chunks of usNIC code in the 1.10.x code base, and --without-usnic only disables one of them. I do believe we fixed that in a later 1.10.x release -- I am guessing you don't want to upgrade to v3.0.x for compatibility/testing reasons, but do you think you could
