I've just spent a couple of days doing this. The main problem I had was
really down to rsh. 
My machine = compton
other = sputnik
another = larwood

on my machine - my account is 'jab'
on other machines (sputnik & larwood) I created accounts for user
'pvm_user' - the reason being, that I wanted to create pvm_user accounts
on all available machines (many more than 3) and then any one of us in
the dept would be able to use pvm without too much account adding (this
idea turned out to be flawed).

on sputnik - in rsh control panel add in user 'jab', and then set it to
access local account of pvm_user,
on larwood - in rsh control panel add in user 'jab', and then set it to
access local account of pvm_user,

if you now 
rsh sputnik -l jab dir
it works !!!
but what caught me out, was if you do this
rsh sputnik -l pvm_user dir
it doesn't. Even though You may have set an account on sputnik which
gives access to pvm_user. 

* * * It seems that whatever you try and do, you must use the account
that you are actually logged on on your machine as. * * *

this means that if I want to use the pvm I need to add in 'jab' entries
i the rsh control panel on all machines I intend to use. If someone else
wants to use it too, they need to add in their ID's too.
But becuase the rsh 'jab' - > maps to account 'pvm_user' on the remote
machine, once the pvm_user account has been set up, any one of us can
add in another account in the rsh control panel which is much easier
than creating a whole new account. The nicebit is the way rsh can change
the account for you. (at least using the ataman software).

PS: I downloaded a file called pvm34rel.zip (or similar, and everything
is working OK, but I also tried pvm34beta4.zip and I couldn't get a peep
out of it).

Compiling the libraries for C++5.02 was a pig, but seem to be working,
and I've now got a small C++Builder program running that shows hosts,
allows me to add/delete them, and generally fart about and experiment.
(PS. also works on win95 machines too)

Don't know if this is any help, but you never know...
