We're having trouble getting CFX-5.6 in parallel between machines running Linux (using PVM). Anyone have any experience with this? Appearantly the rsh get's a '2-user' string or something like it, and PVM doesn't know what to do and hangs up.

Hi,

I was fighting with PVM coming with CFX for about a week. Here is what I've found:

1) version coming with CFX is rather old.Does not matter.What does is, that you need to have running rsh, not ssh with the rsh alias to ssh. (ps -elf |grep rshd)

2) are you able to run a command rsh somehost 'uname -a' and you get the name of the comp without anything else?

3)try to run PVM itself and add the hosts by hand. at the pvm prompt type:
: conf to see the hosts added
: add hostname

I solved the problem by downloading latest pvm compiling it and puting it instead of the original one to $CFXROOT/tools. It is working now, but I can run maximum 3 processes and it is not a problem of a licence.

I'd like to hear what was the solution to your problem.

Jeff,

we set up as described in the Installation Guide and it works fine with up to 4 parallel processes. A little bit tricky is the set up of Linux. What distro are you using? We use SUSE, and by default, rsh is disbaled for security reasons. So, enabling it is necessary but not really straightforward.
