This is a bash builtin thanks to bash-builtins crate.

It provides some information about the cpu affinity, the hostname, SLURM_JOB_ID, SLURM_PROCID and SLURM_LOCALID environment variables if they exists. Optionally you can provide an identifier that will be printed with all the other information using -i option.

Usage

Load the library into a bash builtin using with enable, use it and remove it when you do not need it anymore

$ enable -f target/release/libcpubind_bash_builtin.so cpubind
$ cpubind
myhostname -  -  -  -  - cpu affinity: 0 1 2 3 4 5 6 7 8 9 10 11
$ cpubind -i "id 1 🙂"
myhostname - id 1 🙂 -  -  -  - cpu affinity: 0 1 2 3 4 5 6 7 8 9 10 11
