Nothing. Unfortunately most folks use statically linked binaries for MPI, so .so's are not a factor. I could be wrong, and maybe there is a way to get statically linked binaries to respect LD_PRELOAD or LD_LIBRARY_PATH, but I am not aware of it. More to the point, this dynamic binding allows you to write to the API, present a consistent ABI, and handle the hardware details elsewhere in a driver which can be linked in by the .so/.dll/.eieio method at runtime. Which is about the complexity that most end users/customers want. > > Ashley, -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics LLC, email: [EMAIL PROTECTED] web : http://www.scalableinformatics.com phone: +1 734 786 8423 fax : +1 734 786 8452 or +1 866 888 3112 cell : +1 734 612 4615 _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
