Hey magnum,

Excellent work, much appreciated! However still one typo/bug but easy to

mpicc -c -Wall -O2 -fomit-frame-pointer -I/usr/local/include
-L/usr/local/lib -funroll-loops status.c
status.c: In function ‘status_get_cps_avg’:
status.c:154: error: ‘MPI_UNSIGNED_LONG_LONG’ undeclared (first use in this
status.c:154: error: (Each undeclared identifier is reported only once
status.c:154: error: for each function it appears in.)
make[1]: *** [status.o] Error 1

replace MPI_UNSIGNED_LONG_LONG with just MPI_UNSIGNED_LONG on line 154 of
status.c and all is golden.
