What we have done
The Sbt package has been copied on ui
via svn
We copied the raw data and the config files into ui
via cp
root is in 32-bit version
We compiled the library and the main programs
g++ -m32
Applications run over data and results have been
analyzed
unable to save “.png” figures in root
See here relevant post

What we are doing now
Using WMS and jdl we are trying to submit an
EventReco job
EventReco program needs:
raw data file -> it will be copied to SE and back to WN
config file -> I will use InputSandBox
alignment file -> I will use InputSandBox
EventReco program produces:
rootuple file -> it will be moved to SE
stdout & stderr -> I will use OutputSandBox

What has to be done
jdl:
Executable=”/bin/sh”
Arguments=”EventReco.sh”
InputSandbox=”config file, aligment file”

Conclusions
Ready to copy and register code and data on the
Grid
Jdl and sh wrapper: work in progress

How?
For data: straightforward
For config files:
data on SE
or metadata, via AMGA
e.g. runfile.dat
run number
int
config file align file
varchar
varchar
but config/alignment file per run are more complex
