Summary: Review Request: openmpi - a new MPI implementation https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=173719 ------- Additional Comments From ed@xxxxxxx 2006-02-16 12:29 EST ------- Hi Jason and Orion, Thank you for the responses -- I'm thrilled that other folks are interested in MPI on Fedora! When installing multiple MPI implementations, its best if you avoid putting headers and libs into, for instance, /usr/include and /usr/lib. If you instead put them into, for example, /usr/include/openmpi or /usr/lib/lam then compilers will have to use some sort of environment variables or other build-time information to find them. And thats desirable when installing multiple implementations because it means that, for instance, a particular software build won't accidentally include a lam-provided /usr/include/mpif.h when what you really want is the version at /usr/include/mpich-2/mpif.h. Basically, if we do our best to avoid "polluting" the standard locations then users are much less likely to have problems with side-by-side installs. And yes, I realize that these problems can be fixed by improving the build systems for all the software out there that uses MPI. Good build systems can make it easy to ensure that you get the headers, libs, etc. that you want. But file layout can also make it easier when dealing with the vast number of thrown-together-with-duct-tape build systems that seem to be the norm in the real world. :-) -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. -- fedora-extras-list mailing list fedora-extras-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-extras-list
