[Beowulf] PGI single node licenses, PGI CDK and Clusters

We are looking to upgrade our aged version of PGI CDK (Portland Group
Fortran and C family compilers) on our cluster.  However, since we only
compile our models on the master node we would like to get a single node
license for the master node without using the CDK option and paying the
CDK price (you can only enter our cluster environment through the master
node anyway rather than some clusters where you can join and do your
dogwork on any node).  We would then compile MPICH and move onward.  

We have heard some chatter that we can do this, and we have also heard
chatter that PGI single node compilers (even when run though MPICH) are
hobbled so that they can only be applied to 4 processors (accounting for
dual core systems).  

Obviously we'd rather not shell out big bucks for a PGI CDK kit compiler
that will only be compiling on one node.

Does anyone have any experience or insight on this problem.  

Cheers and Thanks much!
