HI all, On all of my tests write files using MPI_File_write to a current NFS volume is faster than write to PVFS2..
For example, when i increase the number os threads, the bandwith decreases in both PVFS2 and NFS. NFS in the examples have been 20 times faster than PVFS2. Is it correct? I am using a single computer. In 2 computers the results of PVFS2 is slower than using one. Am i doing something wrong to measure band? I am not using too, pVFS2 kernell module, i am using it by MPI IO and MPI ROMIO. Thanks Luiz
