Summary: Review Request: mpich2 - An implementation of MPI https://bugzilla.redhat.com/show_bug.cgi?id=171993 ------- Additional Comments From dledford@xxxxxxxxxx 2008-04-16 16:08 EST ------- I should note that I've made significant changes to lam/openmpi that aren't reflected in Fedora yet. The most important of which is dumping the alternatives usage entirely. It has proven to be unwieldy at best, a nightmare at worst. Instead, my current packages use mpi-selector. You can find mpi-selector, openmpi, and lam packages for the upcoming rhel5.2 release that demonstrate what I'm talking about (and intending to bring into fedora after f9 is released) at my Infiniband package page: http://people.redhat.com/dledford/Infiniband/rhel5.2 Also of note is that, in line with the comments in comment #7 and comment #8, my current packages use %{_libdir}/%{name} as the prefix for all files in the lam package, and %{_libdir}/%{name}/%{version}-%{opt_cc} as the prefix for all files in openmpi (the difference being because I've never been given any requests to have more than one version or compiler of lam installed at a time, but I have been given requests to have multiple versions and multipler compilers of openmpi at the same time). Another item of note is that I have outstanding requests to also include mvapich/mvapich2 in the distro for use over infiniband. I've not gotten any requests for mpich, but then I'm not fully aware of the relationship between mpich and mvapich. However, that does raise the question in my mind of redundancy (I'm not talking about redundant MPI implementations...we're already at the stage of ludicrous there, I'm wondering is mvapich a later version of mpich, are they the same code base, or is the naming similarity coincidence). If these packages are redundant, then would it not be better to use mvapich (which I think supports more of the high speed interconnects natively, but I could be wrong)? If they aren't, then ignore that issue. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact. _______________________________________________ Fedora-package-review mailing list Fedora-package-review@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-package-review
