Blue Waters is Wide

Blue Waters is wide, I can now compile
On stacks of racks my loops will fly.
Give me a code, that will decompose
On many cores, and MPI.

There is a node, runs Fortran or C,
She's loaded deep, with memory,
And with each core, some local cache.
I address it all universally.

Oh, TeraGrid will become XD,
From NSF, comes an RFP;
And centers all, form a TEOS new
For petascale, like the Waters Blue.
