Understood. But since the OpenMPI versions in question are not listed as supported on the ARM/Allinea product page, I thought I’d ask if it is _supposed_ to work before bothering folks with details.
In the meantime, ARM/Allinea has responded so I’ll provide them with the details. But, in short, DDT can’t seem to attach to the 3.0 processes/ranks and just hangs trying. Using the same code, that doesn’t happen with OpenMPI 1.10.2 nor IntelMPI 5.1.1. This is under RHEL 7.4 and launching with srun under SLURM 16.05.11 (for those who want to know).
