PVFS

Join us at the PVFS Birds of a Feather session during Supercomputing '07 next week. The BOF will be held Wednesday (Nov. 14) from 5:30 to 7 pm. We will have presentations on the following topics: PVFS deployment practices on large-scale systems ... [More] , including the PVFS deployment on the new 100 teraflop BGP system at Argonne, presented by Kevin Harms. PVFS as a platform for ongoing research, including OSD integration by Pete Wyckoff, Active Server and File System simulators by Walter Ligon III. Recent new features in PVFS and community discussion of potential features in the coming year. [Less]

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. See the full article in HPC Wire.

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.

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.

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.

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 ... [More] 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. [Less]

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 ... [More] , 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. [Less]

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.

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 ... [More] locations created with versions 1.4.0 or older are migrated to the new format. See this faq entry for further information. [Less]

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 new support for OpenIB, and better 64 bit platform support in heterogenous environments. We also ... [More] 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.
