[gfarm-announce:00018] Gfarm Version 1.0.2 release Available



Hello all,

We are pleased to announce the release of Gfarm Data Grid middleware,
version 1.0.2.  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 support for OpenLDAP-2.1.X or later, additional
syscall hook entries for directory operations, and bug fixes.  We
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 1.0.2
============================

[2004.4.15]

Updated Features

 * Added a new client command; gfwhoami --- prints effective user
   name.

 * Supported OpenLDAP-2.1.X or later (LDAPv3).

 * Supported special characters; ' ', ',', '+', '"', '\', '<', '>',
   and ';' in file names. (bugzilla-ja #13)

 * Syscall hooking libraries

   - Added system call hook entries for directory operations;
     dgetents, dgetents64, open, open64, close, stat, fstat, chdir,
     fchdir, getpwd, and access.

   - Modified semantics of '/gfarm:'.  It is considered to be the root
     directory in Gfarm file system instead of a current working
     directory.  Applications do not assume '/gfarm:' indicates a
     current working directory in Gfarm file system.

   - Changed the way to pass node number and other information to
     a gfarm process, when 'gfexec' command is used.
     *** You do not need to modify application source codes any more ***
     *** to utilize Gfarm file system.  Just link with gfs_hook.o.   ***

     This has a side effect that all gfarm applications need to be
     re-compiled. Or, you may be able to use "-S" option of "gfrun"
     command, if you cannot recompile gfarm applications.

 * Bug fix

   (libgfarm.a)

   - Fixed a bug such that gfs_pio_set_view_*() occasionally returns
     the error message "Success" even when opening a file fails.

   - Fixed a bug of default file view. (Bugzilla #4)

   (gfs_hook.o)

   - Plugged memory leak.

 * Documentation

   (INSTALL) Added the description related to OpenLDAP-2.1.X or later.

   (Gfarm-FAQ) Added section for performance tuning.

   (README.hook) Updated the description.
