SCEC Transfer Issues

Transfer Configuration for 4.4

February 10th, 2014

Postscript handling



- We have implemented a solution in PM-737 to get around condor quoting rules.


- MPI code are not kickstart wrapped

 - Pegasus should indicate whether a clustered job or a kickstart job.


- DAGMan exitcode 



checkpoint jobs

 - 10% of runtimes

 - pegasus-transfer will have to be changed

 - link is set to type checkpoint

 - transaction support for checkpoint

 - timeout  is job runtime - process

 - pegasus-kickstart timeout method

 - also has dv/dt implications for monitoring. 


pegasus-exitcode assumes success and checks for failure

 - refactored the script for unit tests as a library

 - pegasus-statistics

 - pegasus-analyzer  ( maybe some commonality)

 - pegasus python library has to be included in worker package





 - threads are handled similar to pegasus-s3

 - default threading


 - expose options end to end

 - initial threads to irods

 - what options to set


pegasus-config will now work with a source checkout
