Re: [OMPI users] OpenMPI collective algorithm selection

As you noticed the ID of the algorithms are not in any header file, so installing the devel-headers will not help with this particular issue. Hiding the ID of the algorithms has been done in purpose, to prevent people fiddling with one of the most critical pieces in the collective performance

Re: [OMPI users] OpenMPI collective algorithm selection

You can get the headers installed by adding --with-devel-headers to the configure line. On Apr 5, 2013, at 5:10 AM, chandan basu wrote: > Hi, > > I want to use OpenMPI dynamic collective algorithm selection using rules > file, e.g. > > mpirun --mca

[OMPI users] OpenMPI collective algorithm selection

Hi, I want to use OpenMPI dynamic collective algorithm selection using rules file, e.g. mpirun --mca coll_tuned_use_dynamic_rules 1 --mca_coll_tuned_dynamic_rules_file rules.txt ./myexe I can see some examples in earlier discussions (given below). My question is how do I know the ID for the
