Re: [OMPI users] OpenMPI 5.0.0 & Intel OneAPI 2023.2.0 on MacOS 14.0:

Hello everyone, I find your contribution very interesting, because I also use Apple and have been thinking about how I could best install OpenMPI on this device. For example, I have already installed the GNU C-compiler 14 and am very happy with it in conjunction with R - Project. My macOS

We develop and build with clang on macOS frequently; it would be surprising if it didn't work. That being said, I was able to replicate both errors report here. One macOS Sonoma with XCode 15.x and the OneAPI compilers: * configure fails in the PMIx libevent section, complaining about how

Re: [OMPI users] OpenMPI 5.0.0 & Intel OneAPI 2023.2.0 on MacOS 14.0:

I don’t have a solution to this but am interested in finding one. There is an issue with some include statements between OneAPI and XCode on MacOS 14.x , at least for C++ (the example below seems to be C?). It appears that many standard headers are not being found. I did not encounter this

[OMPI users] Avoiding localhost as rank 0 with openmpi-default-hostfile

My openmpi-default-hostfile has host1 slots=4 host2 slots=4 host0 slots=4 and my openmpi-mca-params.conf has rmaps_base_mapping_policy = node rmaps_base_oversubscribe = 1 If I invoke orterun -np 3 on host0, it puts rank0 on host0, rank1 on host1, rank2 on host2. I want it to put rank0 on host1,
