paexec:
- paexec: print exit status of task
- EXIT STATUS section in man page
- SIGUSR2 for graceful exit, i.e. complete currently running tasks
and then exit (Thanks to Mikhailian for idea)
- New option -gg (double -g) for reading graph of tasks in
lower-to-upper order and running new tasks as soon as they appear
on input. If tasks appears on input slowly (distbb/pkgsrc) this
may significantly improve parallelism and reduce total running time
- pamake -- 1) shell/whatever-based script with special section that
describes hosts, dependency graph of targets and other metainfo,
where functions are "targets" 2) preprocessing (m4,cpp,whatever).
Maybe it make sense to see dsh/pdsh.
- mimic dsh and pdsh
- PAEXEC_COMMAND as a default for -c
- pass PAEXEC_NODEID to appropriate nodes
- -n 'server1 server2 +5' two remote servers and five local
- Option -n%'node_[1-20,22-30]'
- non-blocking write(2) for sending task to the slave hosts/CPUs.
- SIGINFO for displaying current status of tasks
- SIGUSR1 for trying restore connection to dead client hosts
