[bgl-discuss] BGL compute node available memory

[chad@xxxxxxxxxxx]

How much physical memory is available to a running process on a BGL
compute node? I've searched google and the ML archive, but so far all I've
found is this:

http://www-unix.mcs.anl.gov/~beckman/bluegene/SSW-Utah-2005/BGL-SSW03-CNK-CIOD.pdf

It shows that the CNK comprises four 256K pieces, and it also shows the
opposite end of memory being reserved for memory-mapped devices (but not
how much is reserved), with the application occupying the space in
between.

Mainly, I'm trying to figure out (at least roughly) how much scalar data I
could fit into a single compute node.

Thanks,
ccg
