We are pleased to announce the release of version 3.3.3 of
the Cooperative Computing Tools, including Parrot, Chirp,
Makeflow, Work Queue, SAND, All-Pairs, and other software.
The software may be downloaded here:
This release includes the following:
Many enhancements to the Chirp-HDFS driver and the Chirp-FUSE module to hide several limitations of HDFS and make the system more easily deployed out of the box.
Added three new batch system drivers for Makeflow: Hadoop,Moab, and Work Queue with a shared filesystem.
Improved support for XrootD. The XrootD libraries are now entirely statically linked to Parrot and included in our binary distributions on Linux.
Added a timeout and retry to Unix filesystem authentication in the Chirp server, to accomodate propagation delays when used with NFS filesystems.
Improved configuration scripts to accomodate a greater variety of Linux distributions.
Updated Parrot to handle a variety of new system calls in RHEL 6.
Many minor bug fixes and improvements.
Many thanks to the following people who contributed to this release: Patrick Donnelly, Michael Albrecht, Peter Bui, and Dinesh Rajan.
