fix cases in ROOT code where we would truncate the TTime (to avoid the
new error messages in TTime operator long on 32-bit platforms).

  Patch for improved performance monitoring. The 'Rate Plot' button in the progress
  dialog is renamed 'Performance plot' and shows up to 4 plots with the event/sec,
  the average read chunck size, the number of active workers and the number of active
  PROOF sessions on the cluster, all as a function of processing time.

  The read chunck size plot allows to monitor the usage of the cache.

  The istantaneous processing rate (event/sec) is now better estimate: a few issues
  with the normalizing times have ben solved, removing the artificial structures that
  were observed.

  The possibility to set a max packet time length is introduced (default 30 s); this
  can be changes with the parameter PROOF_MaxPacketTime.
  The size of the cache is also taken into account to optimize the use of the cache.

  The parameter PROOF_UseParallelUnzip has been introduced to toggle the use of the 
  parallel unzip (default off for now).

  A page describing the new performance plots is under preparation at 
           http://root.cern.ch/drupal/content/progress-dialog

Revision 25827 - (view) (download) (as text) (annotate) - [select for diffs]
Added Wed Oct 15 14:02:59 2008 UTC (6 years, 3 months ago) by ganis

   From Jan:

   - Added the possibility to handle removed workers and partly processed packets. When a worker is stopped
     while processing a packet it finishes, the current event and the rest of the packet is reassigned to another
     worker. This is done via two interfaces:
       - TVirtualPacketizer::AddProcessed(TSlave *sl, TProofProgressStatus *st, TList **)
       - TVirtualPacketizer::ReassignPacket.
   - New class TProofProgressStatus used to keep the query progress stauts in all the TProofPlayer objects and in
     TPacketizerAdaptive::TSlaveStat. This class is also used to structure the relevant information send in
     kPROOF_GETPACKET and kPROOF_STOPPROCESS messages.
   - The class TPacketizerProgressive is removed completely.
   - The PROOF protocol version is increased to 19: this is to handle the changes in the kPROOF_STOPPROCESS and
     kPROOF_GETPACKET messages in Master - worker communication.
