Hello,
Open MPI can support checking API application input/output, by passing
--enable-memchecker to ./configure. When not running in valgrind, this
just adds some nop-like instructions which don't affect the overall MPI
performance. When running in valgrind, this provides very useful
information on application bugs, so it would be very useful to have it
in Debian, at least as a variant.
More details are available on:
