Hi, i tried to run SkaMPI 5.0.4 benchmark on IBM-BladeCenterLS21 system with 256 processors over Infiniband 5 Gb/s, but test has stopped on "AlltoAll-length" routine, with count=2048 for some reason.
I have launched test with: --mca btl_openib_eager_limit 1024 Same tests with 128 processor or less, have finished successful. Different values of eager limit don't solve the problem. Version of OpenMPI involved is 1.2.5. There's someone with this kind of problem over Infiniband? Thanks in advance. -------------------------- Gabriele Fatigati CINECA Systems & Tecnologies Department Supercomputing Group Via Magnanelli 6/3, Casalecchio di Reno (BO) Italy www.cineca.it Tel: 39 051 6171722 g.fatig...@cineca.it
