If there is interest, we could develop proposals on bringing in<br>some of these capabilities into extended collective operations for MPI-3.<br><br>Please see www.data-re.org <br><br>Regards,<br>Tony<br><br><br>-- <br>Anthony Skjellum, PhD<br>Professor and Chair<br>Dept. of Computer and Information Sciences<br>University of Alabama at Birmingham<br>+1-(205)934-8657; FAX: +1- (205)934-5473<br>___________________________________________<br>CONFIDENTIALITY: This e-mail and any attachments are confidential and<br>may be privileged.
