I'm running MPI-IO program to test the write/read performance with pvfs2 file system on a linux cluster. Here are some questions I'm not clear with.
1. For a file in pvfs2 file system, from which IO server the pvfs2 begin to stripe file data? In another word, how to find the first IO server that starts to stripe this file stored in pvfs2 file system? 2. How to change the strip_size? I know we can change the PVFS_DIST_SIMPLE_STRIPE_DEFAULT_STRIP_SIZE value in the source header file: include/pvfs2-dist-simple-stripe.h. But that requires a re-compilation whenever I change the value. Is there a global environment variable that I can set to change the strip size? thanks! xiangyong ouyang _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
