[ROOT] Loop over a tree/ntuple with threads

Hi !
I'm doing an analysis with a modified object which I made by using the
MakeClass() command.

Now I want to speed up the processing of my ROOT-files by implementing a
special Loop() routine which is able to run as a thread. Each thread has

to process only a part of the events and at the end all events in my
ROOT-file are processed and are filled into the same array/histogram of
another file.

The different threads should  run on different computers (or
processors). I'm using the 3.01/06 version on a RedHat 6.1 platform.

Hardisks can be mounted via NFS ...

Is this implementation of a thread possible with f.e. the TThread-class
?

Cheers, Arno Heister.
