e and beeps when the older didn't. Thanks again, AFernandez Indeed, you cannot use "try" as a variable name in C++ because it is a https://en.cppreference.com/w/cpp/keyword. As already suggested, use a C compiler, or you can replace "try" with "xtry" or

[OMPI users] Specifying second Ethernet port

Hello, I'm performing some tests with OMPIv4. The initial configuration used one Ethernet port (10 Gibps) but have added a second one (with the same characteristics). The documentation mentions that the OMPI installation will try to use as much network capacity as available. However, my tests show

[OMPI users] CUDA-aware codes not using GPU

o agree with the lack of GPU use. If I try with '--mca btl smcuda,' it makes no difference. I have also tried to specify the program to use host and device (e.g. mpirun -np 2 ./osu_latency D H) but the same result. I am probably missing something but not sure where else to look

[OMPI users] Seg error when using v5.0.1

Hello, I upgraded one of the systems to v5.0.1 and have compiled everything exactly as dozens of previous times with v4. I wasn't expecting any issue (and the compilations didn't report anything out of ordinary) but running several apps has resulted in error messages such as: Backtrace for this er
