Re: [pooma-dev] ICC and POOMA--versions, CHEETAH, MM, MPICH?

[George Talbot]

Thanks for the info.  Is that what you're using now, the modified
version of icc?

Now when I downloaded the POOMA tarfile, it didn't have a LINUXICC.conf
file in the config/arch directory.  Are you using POOMA from CVS?  Also,
what did you have to do to compile CHEETAH properly?  What version of
that are you using and where did you get it?  Sorry for all the basic
questions, but this stuff has been a bit hard to assemble.

Thanks.
