[mpich-discuss] How to read --pmi-process-mapping

Hello, I am launching 2 processes on 2 nodes. The processes get rank 0 and 1 --version 4.3.0a1 --iface-ip-env-name PMI_HOSTNAME --hostname 192.168.2.100 --global-core-map 0,1,2 --pmi-id-map 0,0 --global-process-count 2 --auto-cleanup 1 --pmi-kvsname kvs_31321_0_150440369_ampere-altra-2-1 --pmi-process-mapping (vector,(0,2,1)) I see once rankmap is generated, its converted to a string “(vector,(0,2,1))”. How do we read this as? Regards, Niyaz
