Open MPI OFED support repositary version
I see OpenSuse 13.1 has ben added to the Repository version but what are
the OFED and Openmpi versions supported/tesed etc ? latest OFED is 3.12 latest Openmpi is 1.8 whereas 1.6 was mentioned in the 2.3.0 executable release |
Greetings Derek,
I'm sorry to say that your questions seems a bit too... diagonal? :confused: I say this because:

Infiniband kernel drivers are provided with Opensuse but you still need to get the OFED libraries rpms
Opensuse 12.3 has Openmpi 1.6.0-3 compiled without Infiniband support To get infiniband to work on Opensuse 12.3 ok, I used Openmpi 1.6.4 compiled with OFED 3.5 libraries. I tried compiling Openmpi 1.6.0-3 with various OFEDS but they didnt work, and it took a lot of work to find the working combination. Opensuse 12.3 is about to go out of support so i need to find out about 13.1 Opensuse 13.1 has Openmpi 1.7.2 as default and I was trying to reduce "varying mileage" to find out what would work. |
Mmm... then it's a tough choice. Open-MPI 1.6 and 1.8 are considered to be stable versions and 1.7 is considered a feature version (i.e., most likely to have more bugs): http://www.open-mpi.org/software/
From this point of view, it's best to build from source code either way. From safety point of view, it would be best to use the latest stable Open-MPI 1.6.5. As for compatibility of OpenFOAM with Open-MPI 1.8, I have no idea. Nonetheless, as I somewhat implied before, it is possible to build MPI support for OpenFOAM with more than one MPI version. Have a look at the file "etc/config/settings.sh" in OpenFOAM's installation and search for this line: Code:
case "$WM_MPLIB" in Quote:

Thanks...
Extra complications are kernel versions Ofed 3.5 supports kernel 3.5 but I got it working with opensuse 12.3 which has kernel 3.7 but i can only update Mellanox firmware under kernel version 2.4 (openSuse 11.4) opensuse 13.1 is kernel 3.11 but ofed 3.12 is kernel 3.12. ahh well it only took me a month to get the last lot working |
Hi Derek,
You might want to at least start thinking in switching to an enterprise-type Linux Distribution, instead of continuing using openSUSE. For example:
