We provide a program in the “test" directory of the HDF5 1.10 distribution - twriteorder.c<https://svn.hdfgroup.org/hdf5/branches/hdf5_1_10_0/test/twriteorder.c>. See description<https://svn.hdfgroup.org/hdf5/branches/hdf5_1_10_0/test/SWMR_POSIX_Order_UG.txt>.
On NFS it fails pretty quickly. We couldn’t make it to fail on GPFS. Please see the report<https://svn.hdfgroup.org/hdf5/branches/hdf5_1_10_0/test/POSIX_Order_Write_Test_Report.pdf>. It would be interesting to run it on PVFS. Elena ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Elena Pourmal The HDF Group http://hdfgroup.org 1800 So.

Basically we need for write ordering to be preserved, which is usually true for a straightforward local file system. Parallel file systems like GPFS are also generally supported. On the topic of parallel file systems, it is unclear if the PVFS (aka OrangeFS) file system is POSIX-enough to support SWMR. PVFS does not implement full POSIX semantics, for performance reasons, but neither is it as sloppy as NFS is. ==rob _______________________________________________ Hdf-forum is for HDF software users discussion.
