Hi Mark,
We are going through a similar experience at one of our customer sites. They are trying to run Intel MPI on more than 1,000 nodes. Are you experiencing problems starting the MPD ring? We noticed it takes a really long time especially when the node count is large. It also just doesn't work sometimes. Regards, Bill. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Hahn Sent: Friday, September 29, 2006 8:47 AM To: Clements, Brent M (SAIC) Cc: beowulf@beowulf.org Subject: Re: [Beowulf] Intel MPI 2.0 mpdboot and large clusters, slow tostart up, sometimes not at all > Does anyone have any experience running intel mpi over 1000 nodes and do you have any tips to speed up task execution? Any tips to solve this issue? it's not uncommon for someone to write naive select() code that fails when the number of open file descriptors hits 1024... yes, even in the internals of major MPI implementations. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
