Hi George,
I'm a member of Fujitsu MPI development team.
Thank you for picking up the issue.
We checked the changesets and unfortunately found they are incomplete.
Our testing method is as follows:
- Using LLVM clang to compile trunk with -ftrapv (integer overflow detection)
because GCC's -ftr

shared L2/L1I caches (core 0 and 1) and
enabled ASLR:
$ mpirun -np 2 taskset -c 0,1 ./NPmpi_pcmpi -u 1 -n 100
Now starting the main loop
0: 1 bytes 100 times --> 17.07 Mbps in 0.45 usec
