From Maarten and Kristjan Gulbrandsen:
Here is the patch with the restructured PROOF code. It parameterizes
PROOF startup, currently implementing "Standard", Condor, MLM and PEAC.
It can easily be extended with other "TProof" classes, e.g. AliEn Proof.
Or what ever next Grid implementation or scheduler comes along.
The MLM, Multi Level Master, code uses a basic packetizer, based on a
MSD (massstorage domain) tag. In MLM mode we have multi-tier client
server setup, like:
client -> super master -> sub master 0 -> slave[0..N]
...
-> sub master M -> slave[0..N]
It also contains a large number of smaller fixes. Credit for most of
the work goes to Kris!
We have tested this on multipe platforms (RH7.3, RH9, SL3) and in
multiple configurations. Should be stable.

From Philippe:
This patch implements support for TTree Friend in the new TTree Proxy
mechanism (See releases notes of ROOT 4.00/08).
For example with the result of tutorials/treefriend.C and the macro print.C:
void print() {
cout << "Entry #" << fChain->GetReadEntry()
<< " and #" << TF.GetReadEntry() << " \t"
<< x << " "; // from the main tree
if (TF.GetReadEntry()>=0) cout << TF.x; // from the friend tree
else cout << "N/A";
cout << endl;
}
You can simply create a Proxy based TSelector with
T->MakeProxy("withfriend","print.C","","nohist");
Then use the resulting file (withfriend.h) as anyother
TSelector script. For example:
T->Process("withfriend.h+","",20);
Or you can generate a simple histogram 2 files fill.C and fillCut.C
root [5] .! cat fill.C
double fill() {
return x - TF.x;
}
root [6] .! cat fillCut.C
Bool_t fillCut() {
return TF.GetReadEntry()>=0;
}
and you can just do:
T->Draw("fill.C+","fillCut.C");
