Simplify enabling of basic feedback.
- In TDrawFeedback::Feedback, call method Draw() of objects not identified as TH1
derivation. This allows user-defined objects implementing Draw to be displayed
via this utility class (request on the forum).
- In TPerfStats, add new histogram TH1I with the packets being processed per worker;
currently this is 0 or 1 but may change in future; it shows which workers are
still active, which may be useful for debugging at the end of query.
- Add new class TStatsFeedback to display in one canvas the distributions for
the events processed per workers, the packets processed per workers and the
packets being processed per worker.
- In TProof::Process, add support for switches "fb=name1,name2,name3,... " or
"feedback=name1,name2,name3,... " in the option field. This enables feedback
for the specified objects, creating a TDrawFeedback object attached to the session.
Feedback for the specified objects is disabled at the end of the query and the
created TDrawFeedback is destroyed.
The special name 'stats' enables the three feedback histograms required by
TStatsFeedback, and uses a TStatsFeedback instead of TDrawFeedback.
The feedback specs are removed from the option field passed to TProofPlayer::Process.

From Marek Biskup:
major new PROOF developments:
- access to PROOF directly via the TChain interface (creating a TDSet
in the background).
- access to PROOF based trees via the TTreeViewer
- fully implemented the TChain/TDSet::Draw() interface.
- PROOF sessions can now be browsed via the TBrowser

From Maarten Ballintijn and Kristj�n Gulbrandsen
a patch and files that complete the benchmark package.
I strongly recommend using this for demos rather then the H1 example.
The README file should walk you through a complete demo, which should
not take more then maybe ten minutes or so. After you have some
data files generated, you can show significant parts of the sytem
in a minute or two.
I added a feedback request api to TProof, this simplifies things
a lot from a usability perspective. I also modified TDrawFeedback
to use gProof by default, again simplifying things.
Kris wrote the support scripts and fixed the benchmark
scripts to read the full Events.
Please try it out and have fun!
It is as simple as this (I use log level 2 to slow things
down a bit :-))
gROOT->Proof()
.L make_tdset.C
TDSet *d= make_tdset("/data1/tmp",2)
TDrawFeedback fb
gProof->AddFeedback("PROOF_ProcTimeHist")
gProof->AddFeedback("PROOF_LatencyHist")
gProof->AddFeedback("PROOF_EventsHist")
gProof->UploadPackage("event.par")
gProof->EnablePackage("event")
gEnv->SetValue("Proof.StatsHist",1);
gProof->SetLogLevel(2)
d->Process("EventTree_Proc.C")

From Maarten:
- new class TParameter
- new class TDrawFeedback
- fixes to the feedback of performance histograms
- selection of the packetizer
- cleanups
Example commands:
gROOT->Proof()
... package setup ...
TDSet *d = make_tdset(2)
gEnv->SetValue("Proof.StatsTrace",1)
gEnv->SetValue("Proof.StatsHist",1)
TList *fb = new TList
fb->SetName("FeedbackList")
fb->Add(new TObjString("EventsHist"))
fb->Add(new TObjString("CpuTimeHist"))
TDrawFeedback *dfb = new TDrawFeedback((TProof*)gProof)
gProof->AddInput(fb)
d->Process("EventTree_Proc.C","")
