Tour de Table
--------------
-Bertrand
Spent some time on PVSS and Root...
Made changes in system/win32 threads to improve use of
multiprocessor/hyperthreaded machines
Made changes in Tsystem and Tapplication for autoload mechanism
Actually working on TThread on Windows and Drag and drop (linux AND
win32)
-Gerri
PROOF:
- working to a patch to:
- implement prioritized resource sharing at worker level following
an idea of Andy Hanushevsky; the processing time of lower priority
users is artificially inflated (by delaying the request for new
packets) by a factor depending on the priority of the group to
which the user belongs.
- implement an interface to chose a ROOT version among a list setup
by the administrator
- implement class, macro loading functionality (ALICE request)
CASTOR related (patch in 5.14.00d):
- modify 'rootd' to prevent failures observed on Castor servers due to
missing $HOME directories
- fix a few problems with globus authentication in Castor environment
(following a request from LHCb)
-Jan
After last PROOF - Alice meeting we were investigating the problems with
some queries being analyzed slowly (spikes in graphs from cocktail tests).
The analysis showed that two slaves on the cluster underperform.
We also did a number of local and PROOF test to compare the processing
rates and identify bottle neck (hard disk / network). After changing
ProofBench, we run PROOF and local ROOT analysis on the same sets of files.
The old ProofBench files were generated with no compression due to the
fact that Branch constructor automagically defaults to no compression,
unlike the tree. Has to changed.
