Progress Done

• Setting up on the EGRIS GRID– CAM program has been set-up and input data loaded into LFC

and SE.– WRF idem.– Both are up and running separately in the EGRIS GRID.

Strategies to be adopted

• Application Flow Control– CAM job running will be responsible of loading the checkpointing

datasets generated into the LFC and AMGA, during the line of execution.

– CAM is implemented in FORTRAN90 and we are deciding the best strategy to insert “GRID instructions” during the execution. Stop the CAM, load data and metadata to catalogs and submitting

the WRF dependents jobs with those datasets. UGLY!!!!! Make system() calls into CAM code to execute catalog commands

but not the WRF job submission. To solve the problem of WRF submission R-GMA or Logging and

Book-keeping in an asynchronous way.

– CAM job should be continue after “GRID failures” then a persistent mechanism is required to control and monitor the job and WRF sub-jobs.

Strategies to be adopted

• UI Portal to manage and monitor CLIMATE jobs– We are exploring alternatives

• Data and metadata managament– Metadata is uploaded using perl script but we are looking the

optimal schema.– Partial dataset access.
