Hello,
I installed OFED 1.0 (mvapich 0.97)and compile Linpack benchmark.
When I run xhpl, the memory usage creeps up with each NB. and as each N changes the memory allocated is not freed.
LAZY_MEM_REGISTER is not defined per http://mail.cse.ohio-state.edu/pipermail/mvapich-discuss/2006-March/000057.html I removed it from Make.mvapich.gen2. tar it back up and reran the install.
change in NB from 144 to 248
