[mpich-discuss] MPICH2 on heterogeneous Cluster

[James Dinan]

Compiler, library, and O/S compatibility notwithstanding, endianness and 
basic type sizes should be compatible between similar-generation AMD and 
Intel systems.

While it's not supported, I have personally seen AMD+Intel heterogeneity 
work.  Your best chance for success is to force as much homogeneity as 
possible: install the same operating system, compiler, etc. on every 
node and compile a single binary that can run on all nodes (to avoid 
different paddings, etc).

Good luck,
  ~Jim.
