[Bioclusters] a cluster tool for admin work

[Joe Landman]

Hi folks:

  I wanted to give a quick pointer to a simple cluster tool I had built
a while ago (that I seem to use everywhere).  It is
yet-another-run-a-command across all the nodes, though it uses ssh,
doesn't require daemons (other than SSH), doesn't send passwords or
usernames, and so forth.

  You can pick it up at
http://scalableinformatics.com/downloads/all-0.25.tar.gz .  Usage is
quite simple:

        [landman@squash.scalableinformatics.com:~/all-1.0]
        69 >./all uptime
        username:
        password:
        ----- machine =crunch:
        .
        .
        .
        .
        crunch: out= 11:03am  up 3 days, 18:03,  4 users,  load average: 0.02, 0.01, 0.00
        ,       error=, exit=0
        ----- machine =squash:
        .
        .
        .
        .
        squash: out= 11:04am  up 8 days, 27 min,  2 users,  load average: 0.48, 0.43, 0.33
        ,       error=, exit=0
        ----- machine =stuff:
        .
        .
        .
        .
        stuff:  out=blank,      error=blank,    exit=blank
        
        
        -------------------
        
        failed machines=stuff
