Hi All, I ran valgrind with mvapich-2.3.5 for a moose simulation. The motivation was that we have a few non-deterministic parallel simulations in moose. I want to check if we have any memory issues. I got some complaints from PetscAllreduceBarrierCheck
Thanks, Fande ==98001== 88 (24 direct, 64 indirect) bytes in 1 blocks are definitely lost in loss record 31 of 54 ==98001== at 0x4C29F73: malloc (vg_replace_malloc.c:307) ==98001== by 0xDAE1D5E:
