Description

src/arch/pami/machine.c contains the following:

#ifdef CMK_BLUEGENEQ
#define SHORT_CUTOFF   128
#define EAGER_CUTOFF   4096
#else
#define SHORT_CUTOFF   1920
#define EAGER_CUTOFF   2000000000
#endif

An eager cutoff of almost 2GB seems way too large, and pamilrts/machine.c defines them as:

#define SHORT_CUTOFF   128
#define EAGER_CUTOFF   4096

Someone with access to one of the PAMI linux systems needs to test this: https://charm.cs.illinois.edu/gerrit/#/c/2977/
