- Recent new features in PVFS and community discussion of potential features in the coming year.
Ultra-Fast PVFS Transport at Ames
Fri, 02 Nov 2007 17:12:00 CDT
Troy Benjegerdes has demonstrated PVFS over Wide Area Infiniband RDMA services.
Troy will be demo-ing the WAN link at Supercomputing '07 in the Ames Laboratory
booth, where PVFS clients will be communicating over the BOREAS and Internet2
WAN links to the PVFS servers running at Ames lab.

in HPC Wire.
PVFS on MIPS
Thu, 25 Oct 2007 16:22:00 CDT
With the acquisition of a MIPS64 based 6000 processor SiCortex machine at
Argonne National Lab, we were able to install and test PVFS on the MIPS64
cores running linux.
Read more
about the Argonne's new SiCortex machine.
PVFS 2.6.3 Released
Mon, 09 Apr 2007 14:14:26 CDT
This incremental release includes fixes for large mpi parallel workloads
where data corruption occurred, and fixes with spurious crashes in
2.4 kernels. Also fixes kzalloc configure checks on older kernels.
You can download the release from the ftp site. See the
download page for more info.
PVFS 2.6.2 Released
Wed, 17 Jan 2007 15:48:11 CST
This is an incremental bug-fix release from 2.6.1. It includes a few
minor bug fixes. See the ChangeLog for details. As always, you can
download it here.
PVFS 2.6.1 Released
Fri, 15 Dec 2006 10:20:11 CST
This is an incremental bug-fix release from 2.6.0. It includes bug fixes
for build failures with certain configure options (--enable-fast) and fixes
for build failures on particular platforms (such as ppc64).
This release also provides support for the linux kernel 2.6.19.
You can download it here.
See the ChangeLog for specific
changes made since 2.6.0. If you are doing a major upgrade from
a previous release (such as 1.5.1 or 1.4.0), please see the release
notes for 2.6.0 as well.
PVFS 2.6.0 Released
Tue, 14 Nov 2006 01:19:00 EST
We've got a new release out with many bug fixes, and some new features.
You can download it here. See the ChangeLog for specific
changes made since 1.5.1. Some of the major changes include:
- A new TROVE method that uses pthreads instead of AIO, and can provide
significant performance improvements over the default trove method which
uses AIO. To enable the alternate trove method, see the
TroveMethod option entry.
- New server config options that allow tuning of the flow buffers, provide
root squash and read only capabilities.
Also, there are a few important things to be
aware of with this release:
- Notice that we've changed the release name
of PVFS slightly. This release is PVFS version 2.6.0.
What was previously
referred to as PVFS2 1.x.x is now PVFS 2.x.x. This allows us to encapsulate
the design version number in the leftmost digit, instead of as part of the
name. See our versioning faq entry for further info.
- As with 1.5.0 and 1.5.1, the storage format is different from the
1.4.0 version and earlier. If you are upgrading to 2.6.0 directly from
1.4.0, you must migrate to the new format. See this faq entry
for further information. If you are upgrading to 2.6.0 from 1.5.x, then no
migration is necessary.
Updates for PVFS v2 driver in ROMIO
Mon, 23 Oct 2006 13:14:21 CDT
In August, MPICH2-1.4.0p1 was released. Since then, we have found and fixed
several bugs in the ROMIO driver. If you are using MPI-IO to access your PVFS
volume, you should apply this ROMIO fixups
patch.
PVFS2 1.5.1 Released
Wed, 28 Jun 2006 18:10:45 CDT
This is a minor release from 1.5.0. It fixes a build problem on systems
with Berkeley DB version 4.2 and older.
Go to the download page to get it.
NOTE: As with 1.5.0, this release provides a new storage format,
and requires that storage locations created with versions 1.4.0 or
older are migrated to the new format.
See
this faq entry
for further information.
PVFS2 1.5.0 Released
Mon, 26 Jun 2006 18:25:45 CDT
We've been working hard on improving the performance of metadata operations
in PVFS2, and have a new release as a result. This release also includes

environments. We also include many bug fixes and other minor feature
improvements.
The download page has all the information.
NOTE: This release provides a new storage format, and requires that old
PVFS2 storage locations are migrated to the new format.
See
this faq entry
for further information.
PVFS2 1.4.0 Released
Wed, 15 Feb 2006 16:05:45 EST

PVFS2 1.0 Released!
Tue, 09 Nov 2004 15:24:35 CST
As part of the development team, we're announcing PVFS2 version 1.0
here in Pittsburgh at the SC2004 conference! PVFS2 is a GPL/LGPL based
parallel file system for cluster-based applications. It logically
groups any number of storage servers into a coherent file system for
use by client nodes, specifically tailored to handle efficient access
to large shared files. PVFS2 supports access via an MPI-IO interface
for high-performance parallel applications, but you can still mount it
like a regular GNU/Linux file system for traditional serial
applications and management. The PVFS2 project is conducted jointly
between the Parallel
Architecture Research Laboratory at Clemson University and the Mathematics and Computer Science
Division at Argonne National
Laboratory. Please feel free to give it a try!
