Selector for PROOF I/O benchmark test.
For the I/O benchmark, event files are read in and histograms are filled. For memory clean-up, dedicated files large enough to clean up memory cache on the machine are read in. Or memory clean-up can be accompolished by system call on Linux machine inside SlaveBegin(..) which should be much faster the reading in large files.

This method must be overridden to handle object notification (the base implementation is no-op).
Different objects in ROOT use the Notify
method for different purposes, in coordination with other objects that call this method at the appropriate time.
For example, TLeaf
uses it to load class information; TBranchRef
to load contents of referenced branches TBranchRef
; most notably, based on Notify
, TChain
implements a callback mechanism to inform interested parties when it switches to a new sub-tree.
Reimplemented from TSelector.
The Process() function is called for each entry in the tree (or possibly keyed object in the case of PROOF) to be processed.
The entry argument specifies which entry in the currently loaded tree is to be processed. It can be passed to either TTree::GetEntry() or TBranch::GetEntry() to read either all or the required parts of the data. When processing keyed objects with PROOF, the object is already loaded and is available via the fObject pointer.
This function should contain the "body" of the analysis. It can contain simple or elaborate selection criteria, run algorithms on the data of the event and typically fill histograms.
