[mvapich-discuss] Registration cache problem

[Alexander Melnikov]

Hey. Can anyone check out a little test (in the attachment)? On each node,
one MPI process starts, a small number of nodes is enough (3-6). We used
the MVAPICH2 library versions 2.3.3 and 2.3.4, the compiler - GCC 4.8.5.
Almost all tests fail (bad data in rcv_thread). However, when the
registration cache is disabled (MV2_USE_LAZY_MEM_UNREGISTER = 0), the error
disappears.
