Project status report [Erica Snider]
- a workshop has been proposed to discuss at CERN 3D reconstruction with ALICE experts, possibly on November 2017
Conclusions
- people interested in the workshop should contact Erica Snider
MARLEY update [Steven Gardiner]
- MARLEY has been refactored, with the introduction of a "helper" class
- introducing time-dependent flux sampling to describe supernova burst timing
- [Thomas Junk] radiological activity generator has something similar (buried in the code) but it's not mapping well, since radioactivity may happen outside the active volume; nucleon decay might be more fitting
Conclusions
- (digression) LArSoft may need light simulation outside the liquid argon "active volume"
Tracking excessive usage of memory at home [Marc Paterno]
- example of how to diagnose bad memory usage by an art module
- the statistics were processed via R, but that's not necessary
- [Thomas Junk] are samples taken at specific framework events? [A] they are
- [Herbert Greenlee] is having large
VSIZE and small RSS "bad"? [A] often monitoring systems track VSIZE to enforce memory usage limits, so this ends up falling in the "bad" class
- [Herbert Greenlee] is
artsupport being distributed as UPS product? [A] no, it's a R package
- [Erica Snider] is there anything else in the database? where do we find documentation on its content? [A] the content of
MemoryTracker and TimeTracker are documented in art wiki; SQLite can provide runtime description of the schema
- [Gianluca Petrillo] how is this portable? [A]
MemoryTracker will not work on OSX, the numbers being tracked and the ways to track them being inherently different
Conclusions
- the material will be updated with links to art
MemoryTracker
