AlltoAll is a real thing used by real codes, but do keep in mind that there are many algorithms for AlltoAll with various message sizes and network topologies, so it's testing both the raw interconnect and the AlltoAll implementation. I don't know of the results you mention were run with an optimal AlltoAll... do you? -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
