Acitrezza, First Internaional Grid School for Industrial Applications, FEMM – Previous planning … Understand why the Xvfb fails Tuning the application on the Grid Make the JDL parametric (internally or externally)

Acitrezza, First Internaional Grid School for Industrial Applications, FEMM – Xvfb got core Running a xclock before the wine call wine & FEMM did not fail Avoiding xclock, wine & FEMM failed because the Xvfb got a core Several tests were done directly on a WN logged as one of the available pool accounts in order to understand why such strange behavior

Acitrezza, First Internaional Grid School for Industrial Applications, FEMM – still.wine Local tests on a WN gave us the impression that the problem is due to the generation of the.wine directory when wine first starts Starting wine –-version before to start wine femm.exe… the Xvfb does not fails. Although the.wine generation can be an acceptable answer to the strange wine+FEMM behavior, this does not answer why running xclock before wine+FEMM, the Xvfb does not fail.

Acitrezza, First Internaional Grid School for Industrial Applications, FEMM – Future steps Install wine on GILDA, since wine is a powerfull opportunity to run WINDOWS applications on the GRID Try the FEMM JDL and scripts on GILDA Make the final JDL parametric (internally or externally)

Acitrezza, First Internaional Grid School for Industrial Applications, A very simple control on the WN THE SCRIPT … echo "Starting xconsole" export DISPLAY= :0.0 xterm& XTERM_PID=$! touch ctrlfile while [ -e ctrlfile ] do sleep 1 DT=$(date) echo "Timestamp: "$DT >> timestamps done echo "[END]" This solution needs a client having public IP THE JDL Type = "Job"; JobType = "Normal"; Executable = "/bin/bash"; Arguments = "script.sh"; StdOutput = "test.out"; StdError = "test.err"; InputSandbox = {"script.sh"}; OutputSandbox = {"test.out","test.err"}; RetryCount = 4
