=============================== Release Notes for PEGASUS 3.0.1 =============================== This is minor release, that fixes some bugs discovered after 3.0 release and some enhancements. NEW FEATURES -------------- 1) Pegasus VM Tutorial updated The Pegasus VM Tutorial has been updated to use a new smaller Virtual Image running Debian 6 on x86. The tutorial notes are available online at http://pegasus.isi.edu/wms/docs/3.0/tutorial_vm.php 2) pegasus-plots improvements The worklfow gantt chart produced by pegasus-plots now has better legend placement. The legends are placed below the x axis so that they dont interfere with the chart in the plotting area. Also the gantt chart generated now uses a fixed pallete of colors to assign colors to the different compute jobs in the workflows. Earlier, random colors were assigned to the compute jobs. Bugs FIXED ---------- 1) In the case where symlinking was turned on and the pool attributes of the source URL ( discovered in the Replica Catalog ) matched with the compute site, the source URL was not converted to a file URL. This lead to the symlink job failing when the workflow executed. This is fixed now and the planner now converts the source URL's used for symlink jobs to a file URL scheme. 2) Metrics displayed by pegasus-statistics were not clear as to what the worfklow execution time was, as two metrics with similar meaning were displayed ( Workflow Execution Time and Workflow Walltime ). The metrics names have been changed and the meaning of the metrics are explained in detail in both the output of pegasus-statistics and in the online user guide. http://pegasus.isi.edu/wms/docs/3.0/monitoring_debugging_stats.php#id2841404 Additional clarifications have been made to as how the metrics calculations happen on hierarchal worklfows. 3) pegasus-transfer when in file copy mode complained if the destination file already existed. This is now fixed . 4) pegasus-bug-report was broken in 3.0 release. This is now fixed. 5) Added support in pegasus-monitord for handling SUBDAG EXTERNAL jobs without the DIR option.
