Dear Guru's, We're working on a 64 node dual core Opteron cluster with a wide variety of mpi heavy applications and have run into the typical funding issues that are forcing some configuration restrictions (down sizing our wish list). The original concept included the 64 dual processor dual core nodes with an Infiniband 9288 or 9096. As a means to reduce our cost the suggestion was raised to cascade 4 9024 switches. Just wondering how severe the hop penalty might be? My best to you Laura
