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. _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
