when you mention diferences between pvfs2-client-core and pvfs2-sysint applications, one difference is that only pvfs2-client-core makes use of PVFS_sys_testsome, whereas the pvfs2-sysint tools use our blocking routines, implemented with PVFS_sys_wait. Just throwing that out there. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-developers mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-developers
