32 bit, at least for the near future.  The trend seems to be toward 
constant-size or slowly increasing size memory on compute nodes and more 
cores per node, at least on the IBM BG side (not sure about Cray in the 
longer term).  I think that will only change as codes start to do more 
shared memory on nodes overall, and even then maybe not.  Going to 64 
bit does increase the size of things, and on machines with only 512MB 
per core that can matter.
