Dear,

I have no great experience with PVM yet, and am having trouble.

I have two machines, say ibm1 and ibm2, both RS6000, running
AIX3.2.5 and AIX4.1.4 resp. and have PVM3.3.10 at hand.

On ibm1 I have a .rhosts file like :

ibm1.rug.ac.be patrick
ibm2.rug.ac.be patrick

On ibm2 that .rhosts looks like :

ibm2.rug.ac.be patrick
ibm1.rug.ac.be patrick

I can do rsh from both machines to the other.

I have installed PVM3.3.10 in $HOME/pvm3 on both machines.

I have two hostfile files. The first on ibm1 is :

ibm1 sp=1000
ibm2 sp=4000

On ibm2 this becomes :

ibm2 sp=4000
ibm1 sp=1000

I can start up pvm from both machines. E.g. on ibm2 I type :

pvm
>pvm add hartree1

and conf shows two boxes; and I find pvmd3 is running on both. SUCCES

Same story starting from ibm1. (do NOTE that in .rhosts I have domain extensions,
in hostfile I have not, is this a problem ?).

The same goes for ibm1.

Now from ibm1 I type pvm hostfile, and I get the two machines.

When doing this very same from ibm2 I get in trouble ! He won't let me see
ibm1 ! If I change .rhosts by deleting the doamin extensions I get no benefit.
If I change hostfile and include the domain : no succes again.

It seems that whatever I do, ibm1 will let me start up with a hostfile,
and ibm2 does not. /tmp/pvml... teaches me nothing.

What to do,
