Set root version when using Prun

Roofit and RooStats
1

Hi,

Im using RooFit/RooStat to set limit based on the Profile LLR .
For that im generating pseudo-data and running the RooProfileLL to get the method to get
the profile values. The code is compiled and works fine in root 5.28.

Since to get the distributions is very time consuming, i would like to submit the job to the grid (unfortunately
i do not have access to other cluster from my group).

The only way im aware of is to use prun. However, for that i need to use an athenatag (from ATLAS code).
The root version associated to the latest athena tag is 5.26.

In root 5.26 the code compiles but has problems when doing the fit (maybe a subject for a new thread).

So im wondering if it’s possible to set a root version independently of the athena release.

Btw, is there other way to send this kind of jobs to the grid?

Thanks a lot in advance,
Cheers,
Xabier

[quote]So im wondering if it’s possible to set a root version independently of the athena release.[/quote]This is really a question of the maintainer of prun and/or athena. A priori there ought to be a way for you to distribute/use arbitrary software on the grid node (you may have to build a version of ROOT suitable for the grid node you use).

You may want to investigate “Proof On Demand”: www-linux.gsi.de/~manafov/D-Grid … p/POD.html which may simply your problem.
