Apropos configuration parameters for packaging:
Is there a significant benefit to configuring built-in memchecker
support, rather than using the valgrind preload library? I doubt being
able to use another PMPI tool directly at the same time counts.
Also, are there measurements of the performance impact of configuring,
but not using, it with recent hardware and software? I don't know how
relevant the results in https://www.open-mpi.org/papers/parco-2007/
would be now, especially on a low-latency network.
