It runs Linux on 1024 I/O nodes (no user code directly executes on the
I/O nodes) and a bunch of service nodes (to run proprietary DB2 as a
repository for static and dynamic system states, proprietary XL
compilers and other very proprietary stuff). 65536 performance critical
compute nodes run "compute node kernel" (aka The ?Blue Gene/L Run
Time Supervisor? BLRTS, pronounced "blurts") -- a simple lightweight
single-user operating system, does not need to implement any context
switching, motivated by Puma and Cougar kernels at Sandia national Lab
and Univ. of New Mexico. It's proprietary IBM code developed from
scratch and optimized for Blue Gene.
