Hi all,

For those interested. I made some significant updates of the MPI tools. Checkout the README file in ../pandaroot/PndTools/mpiTools/ to see what this tool can do for you.

Some of the updates are:

* Optimized boss-worker handshaking mechanism
* Improved error handling: failure results are send back to boss process, option to do a validation of the results
* A more flexible job description file with the option of user-defined parameters (dynamic)
* Added the option to download input data (remote or local) prior to the job
* execution scripts can be stored remotely (copied automatically)
* Bug fixes and code tested/debugged with MPICH and OPENMPI on PBS cluster in Groningen and on various multi-core platforms.
* Flexible and improved run numbering
* Added extensive example scripts with validation
* Added statistics output (run time)
* Job merging improved by using a BARRIER synchronization mechanism. Example scripts are included in the repository.
* Checks on disk storage and number of processes still pending with automatic hold


Johan.
