Did you use cp(1)? Try measuring performance with the pvfs2-cp utility: it uses a larger block size and should give you a better initial value for single-node performance. > So I have questions. PVFS2 say it support IB. It means IP over IB or RDMA > over IB?? It is possible both? I'll have to defer to Pete on this one. I think it supports real RDMA over IB. If you want to run IP over IB, then I think you would just use tcp. > In addition I want to know how to configure pvfs2 with IB. I think you've done everything correctly. Tell us how you measured the slow performance and we can either fix it or suggest other approaches. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Labs, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
