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

Hello OpenMPI Team, I'm trying to use CUDA-aware OpenMPI but the system simply ignores the GPU and the code runs on the CPUs. I've tried different software but will focus on the OSU benchmarks (collective and pt2pt communications). Let me provide some data about the configuration of the system:

[OMPI users] Specifying second Ethernet port

2019-05-17 Thread AFernandez via users
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
