[mpich-discuss] Heterogeneous systems

[Pavan Balaji]

Even 1.0.7rc1 does not support heterogeneity. However, if you don't mind 
a small performance difference, you can just compile the code on the AMD 
system with a 32-bit compiler. Though I've not fully tested it, my 
initial testing seems to reveal that things work fine with this. Here's 
the configure command line if you need:

  $ CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 F90FLAGS=-m32 ./configure
