[Beowulf] newbie question about mpich2 on heterogenous cluster

Dear List

I installed mpich2-1.0 on my little cluster (2 Linux nodes and 3 Solaris 
nodes). I first worked only on the two linux nodes, where the programms run 
without troubles. But when I would like to invoke the solaris nodes, i.e. 
when I run the programs on a heterogenous cluster, it ents up in error 
messages. For some reoson, the -arch parameter is not implemented in 
mpich2-1.0. 

Does anyone have experience with such problems? Can I run mpich2 on a 
heterogonous cluster?

Thanks in advance for any help
