Beta sites needed for ZZZZZZ 4.0

[Gijsb. Wiesenekker]

ZZZZZZ 4.0 will include a parallel alpha-beta routine
The parallellism will be built around a public domain
massively parallel computing environment, PVM.
In ZZZZZZ 3.5 the program par.c will already be replaced
by PVM code.
I am looking for beta sites so that I can test the
parallel code.

I WILL NEED FOR THIS AN ACCOUNT ON YOUR UNIX MACHINE
PERMANENTLY. ALSO RLOGIN, REMSH AND RCP SHOULD WORK.

Read on if you can arrange for this.

Do the following:
set up an account with username 'wiesen'.
The login shell should be 'zsh' if you have it,
otherwise 'sh' (NOT csh).
Create a file /tmp/zzzzzz_idle if your machines is idle,
remove it if not. This can be easily done with cron, e.g.
If you know that your machine is idle mon-fri from
22.00 to 5.00 and in the weekend, include the following
cron commands in your crontab file:
#enable mon-thu at 22.00
0 22 * * 1-4 touch /tmp/zzzzzz_idle
#disable tue-fri at 5.00
0 5 * * 2-5 rm /tmp/zzzzzz_idle
#enable fri at 22.00
0 22 * * 5 touch /tmp/zzzzzz_idle
#disable mon at 5.00
0 5 * * 1 rm /tmp/zzzzzz_idle

Mail wiese...@sara.nl the name of your machine and the
password when you have set it up.
