[gfarm-announce:00021] Gfarm Version 1.0.3 release Available

[Osamu Tatebe <o.tatebe@xxxxxxxxxx>]

Hello all,

We are pleased to announce the release of Gfarm Data Grid middleware,
version 1.0.3.  Gfarm is a reference implementation of the Grid
Datafarm architecture designed for Petascale Data-intensive computing.
It provides a global file system using local disks of cluster nodes,
and supports data-parallel execution via file-affinity scheduling.

This release includes a critical bug fix of the version 1.0.2 such
that legacy applications cannot be executed in parallel, and several
major bug fixes.  Although this release requires recompilation of
every application, we strongly encourage all to upgrade to this
version.

The software can be downloaded from: http://datafarm.apgrid.org/

Bug tracking system is available at http://datafarm.apgrid.org/bugzilla/

Release note for Gfarm 1.0.3
============================

[2004.5.25]

Updated Features

 * Added new I/O functions; gfs_mkdir, gfs_rmdir, gfs_pio_gets,
     gfs_pio_readline, gfs_pio_readdelim.

 * gfrmdir - it terminates very quickly. (Bugzilla-ja #20)

 * gfstat - it also displays the information of assumed fragment
     number. (Bugzilla-ja #16)

 * gfexec - The way to pass node number and other information to a
     gfarm process is changed again to be able to be inherited by any
     child process.
     ** This has a side effect that all gfarm applications need to **
     ** be re-compiled.                                            **

     '-s', '-I', '-N' options are added.

 * Bug fix

   (libgfarm.a)

   - Fixed a segfault problem especially when using syscall hooking
     library.

   - Fixed a segfault bug in gfs_pio_fileno(). (Bugzilla-ja #25)

   (gfs_hook.o)

   - Fixed a bug such that select() results in timeout when checking
     readability of a file descriptor for a remote Gfarm file.

   - Fixed a bug such that a parallel process cannot be executed
     correctly, which was introduced in the version 1.0.2.

   - Fixed a bug when hooking fstat().
