[MPICH] MPICH 105, SUN NIAGARA dead in the water

[chong tan]

shm/ssm  : dropped pacakge
nemesis   : not supported
socket     : works, but very-very-very-slow due to the number of communication.  In one test, with 26 billion send+recieve, 6 processes with MPI is more than 10X slower than uni-process  (uni-process takes 15 hours)


any suggestion ?

thanks

tan
