Riccardo Bruno INFN CT

2. FEMM – Previous planning …
Planned steps
Site installation of Wine+Xvfb and publishing their relative software tags
Development of a first JDL
Test of the JDL
Tuning the application on the Grid

3. FEMM – SW Installation
Site installation of Wine+Xvfb and publishing their relative software tags
Rosanna C. as Site Administrator of this school installed for us the required software
Wine comes from RH9 RPM
RPMs make easier installation on Grid
Xvfb Already available from SLC 3.x sofware repository

4. FEMM – The JDL Type = "Job"; JobType = "Normal";
Executable = "/bin/sh";
Arguments = "script.sh message!";
StdOutput = "femm.out";
StdError = "femm.err";
InputSandbox = {"script.sh","femm.tar.gz","SyncRel.lua","SyncRel.fem"};
OutputSandbox = {"femm.out","femm.err","flussi_syncrel.txt"};
RetryCount = 4
The JDL consists of a normal job
The Argument to the script is introduced for future uses

5. FEMM – files of femm JDL
FEMM application files have been collected and inserted to a TARBALL file
./MFC42.DLL
./fkn.exe
./femm.tlb
./license.txt
./matlib.dat
./triangle.exe
./femmplot.exe
./statlib.dat
./belasolv.exe
./femm.exe
./MSVCRT.DLL
FEMM input files:
SyncRel.fem SyncRel.lua
FEMM output files
flussi_syncrel.txt

6. FEMM – Testing JDL Testing of the JDL gave several problems due to
MFC42.DLL was not caught by WINE when first attempting to copy the whole .wine directory
Xvfb gave us problems due to its control directory/files: /etc/X11-… and lock file /etc/X1.lock
Before to obtain a first success a cleaning of ALL WNs was necessary
Rosanna C. as site admin of this school grid, cleaned the directories.

7. FEMM – The running script
HOSTNAME=$(hostname -f)
USER=$(whoami)
ARG1=$1
LOCALDIR=$(pwd)
echo "HOST: "$HOSTNAME
echo "USER: "$USER
echo "ARGS: "$ARG1
echo "LOCALDIR is: "$LOCALDIR
echo "HOMEDIR is:"$HOME
...
echo "Unpacking TAR"
tar xvfz femm.tar.gz
echo "Starting Xvfb"
Xvfb :1 &
XVFB_PID=$!
sleep 2
export DISPLAY=:1
echo "Starting test xclock"
xclock &
XCLOCK_PID=$!
echo "Starting WINE and FEMM"
wine femm.exe -lua-script=SyncRel.lua -windowhide
WINE_PID=$!
sleep 2
...
echo "Closing xclock"
kill $XCLOCK_PID
echo "Killing Xvfb"
kill $XVFB_PID
rm -rf /tmp/.X11-unix
rm -rf /tmp/.X1-lock

8. Understand why Xvfb failed Tuning the application on the Grid
FEMM – Future steps
Understand why Xvfb failed
Tuning the application on the Grid
Make the JDL parametric (internally or externally)
