mosbatch command requires a newline on stdin

Question

In the newest version of MOSIX (3.14.0.12), all mosix commands which launch on a remote node (mosbatch and mosrun -M) do not quit until I tap the return key. The command properly executes on the remote node, disappears from the remote node process list, but nothing happens until I tap that return key.

For commands which do not read from STDIN themselves, the following works:

echo | mosrun -M -3 echo bla

Needless to say, this is very annoying. And of course, the above only applies to commands that do not read STDIN. My mosix cluster becomes completely unusable. Where could I start to look for the solution to this issue?

Corrolary: Are there other locations I would be better off posting this question? Newsgroups/mailing lists?

Answer 1

The only correct answer here seems to be:

Mosix is not used in public clusters anymore. Currently, it is only used at the Hebrew University of Jerusalem. The publication history on Mosix suggest this: all papers published on the system originated from the University of Jerusalem. The OpenMosix project, a fork from late 2001, is also dead as of March 1st 2008 see Wikipedia

No public forums on Mosix exist. The HPC community moved on to using job scheduling systems like SLURM, SGE or TORQUE.

Currently, it is best to move away from Mosix. A lot of universities already did (e.g. Uppsala university replaced Mosix with SLURM).

Answer 2

You could always just wrap that into a bash or zsh function to make it quicker to type, not an exact answer but I figured it could be helpful:

qmosrun() { echo | mosrun $@ echo bla }

(qmosrun for quick mosrun).

EDIT: Oh and if you've got any questions you could try checking out the openMOSIX IRC channel, on irc.freenode.net on #openMosix . I'm not sure whether you're on mosix or openmosix but it's likely a good place to find some people to talk to regardless http://tldp.org/HOWTO/openMosix-HOWTO/x1840.html
