and Scaling

• The processClump step is taking ~40 hequ-minutes (or ~65 fell-minutes). With >500 simultaneous jobs running, there is little noticeable strain on xroot.
• The mergeClumps step is taking ~5 hequ-minutes
• It was observed that submitting 70 runs at once put a strain on /u30, home of GlastRelease. Some 93 of ~540 jobs failed with I/O error, but succeeded upon rollback.

P120-FT1

Status chronology

...

Note on diffuse response calculation: gtdiffrsp is called three times in succession. The first time with IRF P7_v2_diff and evclsmin==8, followed by IRF P7_v2_extrad and evclsmin==9, and finally IRF P7_v2_datac and evclsmin==10. The resulting FT1 file has six columns of diffuse response, two columns (galactic and extragalactic response) for each of the three IRFs. This creates a non-standard FT1 file by FSSC standards as they expect only five diffuse response columns.
