This may be the result of running on a system that does not support memory hooks or having some other software subvert Open MPI's use of the memory hooks. You can disable Open MPI's use of memory hooks by setting both the mpi_leave_pinned and mpi_leave_pinned_pipeline MCA parameters to 0. Open MPI will disable any transports that are attempting to use the leave pinned functionality; your job may still run, but may fall back to a slower network transport (such as TCP). rcache name: %s Process: %s Local host: %s # [cannot deregister in-use memory] Open MPI intercepted a call to free memory that is still being used by an ongoing MPI communication. This usually reflects an error in the MPI application; it may signify memory corruption. Open MPI will now abort your job. rcache name: %s Local host: %s Buffer address: %p Buffer size: %lu
