[pooma-dev] Compile Time Problems and Pooma 2

[Julian C. Cummings]

Dave,

I don't have an account on chi, but I do have an account
on the Compaq TeraScale machine at Pittsburgh Supercomputing
Center.  It has the same Compaq Tru64 operating system, but
I don't think they have KCC installed.  I should probably
have a look at building Pooma 2 there using the Compaq compiler.
I might be able to help Lee with Pooma 1 issues, but it would
make more sense to get an account on your chi machine first.

Julian C.
