Update

A number of things changed on fimm since the workshop 19/3-09

/work/atlas was broken by some cleaning script! for now use /work2/atlas instead
I have removed the old atlas installations, we now use the grid installations
- to see what versions are available use
```
sh /work2/atlas/install_scripts/list_athena_release.sh
```
(current list: 14.2.10 14.2.10.1 14.2.23 14.2.23.2 14.2.23.3 14.2.25 14.2.25.6 14.2.25.8 14.5.0 14.5.0.7 14.5.1 14.5.1.2 14.5.1.3 14.5.2 14.5.2.1 14.5.2.2 14.5.2.3 15.0.0)
- to get an athena environment use
```
source /work2/atlas/install_scripts/setup_athena.sh version
```
  (where version is one in the previous list)
- to get a work area use
```
source /work2/atlas/install_scripts/setup_athena_workarea.sh
```
for now dq2 is broken, avoid it, if you need it use it on lxplus and scp the files to fimm
make sure everyone can see your files, please run the following commands
```
chown -R ${USER}:atlasuib /work/${USER}  /work2/${USER}; chmod -R g+r /work/${USER} /work2/${USER}
```
and in case you have something in /workX/users/ do the same for these files
With interactive jobs one can run ATLAS eventviewers on fimm, try it - its awesome
```
ssh -X ${USER}@fimm.bccs.uib.no
```
```
qsub -I -X
```
(the -X's are for X window forwarding, you must use these)

(wait until prompt changes to interactive job, often quick, but can take some minutes) in the job get a workarea
```
source /work2/atlas/install_scripts/setup_athena.sh 14.5.2.3
```
```
source /work2/atlas/install_scripts/setup_athena_workarea.sh
```
and in the prompt run either atlantis or vp1
