Release Notes: Work Queue now allows you to specify chunks (pieces) of an input file to be used as input for worker tasks. Makeflow now supports a -i switch which outputs pre-execution analysis of the Makeflow DAG. Work Queue and Makeflow support submitting tasks to the PBS batch submission platform. The Makeflow makeflow_log_parser now ignores comments in Makeflow logs. Work Queue supports querying workers and tasks at run-time. Makeflow Input file (dependency) renaming is supported with a new "->" operator. Work Queue Tasks are now killed using SIGKILL. Work Queue Protocol based keep-alives were added to workers.
Release Notes: In WorkQueue, memory errors that lead to a SEGFAULT, race conditions in signal handling for workers, and incorrect handling of the -C option where a worker would not use the same catalog server as work_queue_pool were corrected. Tasks now have a unique process group to properly kill all task children on abort. Escape codes such as \n and \t are now properly interpreted in Makeflow files.
Release Notes: A bug in WorkQueue that resulted in a cancelled task becoming a zombie was fixed. Various corrections were made to the manual and HTML documentation. Makeflow -I and -O options now correctly the output file list to stdout. WorkQueue now correctly removes directories during cleanup.
Release Notes: WorkQueue now has a new API for logging, improved python binding support and documentation, and various other bugfixes and minor features. Makeflow now supports garbage collection of intermediate files, lexical scoping of makeflow variables, and a new MAKEFLOW keyword for recursive makeflows.
Release Notes: This release improves debugging messages in Work Queue, fixes a bug in Work Queue which caused the stdout buffer not to be reset at the beginning of every task, fixes a bug which made pool configurations with an absolute path result in a segfault, and adds support for workers using Torque.
