> In a distributed parallel computing scenario, dumping stacks from 64 processes via a signal handler would have created 64 different files scattered in 64 different remote filesystems. I was working on a cluster and often needed to do the same thing on all the nodes, run some database query or os command, and gather and integrate the results. I wrote yet another Python stream-objects-instead-of-strings shell (https://geophile.com/osh https://geophile.com/osh), which included features for distribution: Run the same command on all nodes, bring back the results, merge streams, gather files, distribute files, etc. That was several years ago, and it wasn't a full shell. Since then, I've done an improved system that actually is a shell (https://marceltheshell.org https://marceltheshell.org, https://geophile.com/marcel https://geophile.com/marcel).
