The competition probably shouldn't be full Unix, and in Blue Gene, for instance, it wasn't on the compute nodes.
I don't know exactly what the current Cray environment is like -- it used to be rather odd -- but most HPC systems run normal EL-ish distributions. Summit is RHEL8, and mostly uses GCC, not XL according to https://gcc.gnu.org/wiki/cauldron2022talks?action=AttachFile&do=view&target=OpenMP-OpenACC-Offload-Cauldron2022-1.pdf https://gcc.gnu.org/wiki/cauldron2022talks?action=AttachFile...
- pjmlp 4y agoSure, however they are mostly UNIX inspired if you will, as anything else.
- gnufx 4y agoSingle-user, single-program doesn't seem very Unix-y to me: https://en.wikipedia.org/wiki/CNK_operating_system https://en.wikipedia.org/wiki/CNK_operating_system There was also Plan 9, but I don't know if it was ever actually used: https://doc.cat-v.org/plan_9/blue_gene/ https://doc.cat-v.org/plan_9/blue_gene/
