[Reduce-algebra-developers] Running reduce on remote machines

[Raffaele V. <raf...@un...>]

Dear All,

I'm developing reduce software for computations in the geometry of
differential equations. The computations are quite heavy, so after 'easy'
cases I would like to run the software on a server. This means log in into
a server via ssh, launch the computation, logout, and then login the day
after and see the results.

But here I have the following problems:
1 - using `nohup reduce -w infile -- outfile &' does not work because (I
guess) reduce refuses to go in background. As I try to run a computation
in background the job stops.
2 - using gnu screen does not work because after I logout and login again
the screen sessions holding reduce computations are `dead' (in screen
terminology). screen keeps reduce working only if I do not close the ssh
connection.

The above problems happen both with latest binaries and with 20101007
binaries from Sourceforge, my local and remote systems are Ubuntu 64bit.

The only thing that works is vnc; for the moment it is a good solution.
I suspect that the above two problems have the same origin, but I have no
clues... of course I can use vnc forever but it would be nice to know what
is going wrong.

Thank you very much and best wishes,

raf.
