The Cooperative Computing Lab is pleased to announce the release of version 3.6.2 of the Cooperative Computing Tools, including Parrot, Chirp, Makeflow, WorkQueue, SAND, All-Pairs, and other software.

This is a bug fix release of version 3.6.1. No new features were added.

The software may be downloaded here:


  • [WorkQueue] Corrected memory errors leading to a SEGFAULT. [Li Yu]

  • [Makeflow] Properly interpret escape codes in Makeflow files: \n, \t, etc. [Brian Du Sell]

  • [Parrot] Watchdog now properly honors minimum wait time. [Li Yu]

  • [Parrot] Reports the logical executable name for /proc/self/exe instead of the physical name. [Douglas Thain]

  • [WorkQueue] Corrected incorrect handling of -C option where worker would not use the same catalog server as work_queue_pool. [Li Yu]
