New features and improvements:
New comprehensive documentation and man pages for all commands.
New support for python and perl bindings to the Work Queue system.
New support for running work queue applications directly on EC2.
New example application of replica exchange using Work Queue.
Parrot-XRootD support is now statically compiled in the binary release.
Improved scalability of ticket-based authentication in the Chirp server.
Improved support for HDFS as storage driver in the Chirp server.
Improved Chirp server architecture uses multiple processes for robustness.
Improved build system now handles portability across multiple operating systems (linux, solaris, macos, freebsd, cygwin) and architectures (x86, x86_64, ia64, ppc)
Bug fixes:
Fixed bug in Chirp chdir() that was seen as a No such directory error when using FUSE.
Fixed bug in Chirp tickets triggered by variable output from openssl.
Fixed bug in Parrot relating to poll(), which would result in long timeouts when using python or mpich.
Fixed bug in Parrot relating to tc{get/set}pgrp(), which would result in no prompt displayed in interactive root.
Fixed bug in the catalog server that would result in a crash when under heavy load.
Many members of the CCL team contributed to this release:
Michael Albrecht contributed the MPI Work Queue implementation, and generic support for batch systems with a qsub-like interface.
Peter Bui contributed the SWIG Perl and Python Work Queue bindings, the Starch tool, found many bugs throughout the code, and generally wrangled the build system.
Patrick Donnelly contributed the ticket authentication system and the Chirp-HDFS support.
Dinesh Pandiar contributed replica_exchange_protomol, ec2_{submit/remove}_workers, and multiple improvements to Work Queue.
Li Yu contributed to the Work Queue implementation.
The entire CCL team worked to complete the documentation.
And we also thank:
Nabil Ghodbane for assisting with parrot_run and ROOT.
Vanessa Hamar for assisting with parrot_run and mpich.
Rodney Walker for assisting with the chirp_server.
RJ Nowling and Badi Abdul-Wahid for assisting with the Work Queue system.
