Introduction
The MC production on the grid includes G4BeamLine simulation and G4 Detector simulations using MAUS.
MAUS G4 detector simulation production, using already made G4BL libraries, was done upon request with no delays, since March last year.
As of March this year, the G4BeamLine production was restarted on the grid.

4. MCproduction on the grid information pages
Information about finished and running MCproductions on the grid:
Information ( and also as examples ) of MCproduction Requests
Information about MCproduction requests entries in CDB
You can check MCSerialNumber entries in CDB:
The scripts used for MC production on the grid are available on launchpad

Comment on requests
Ideally, all requests should have exact path of G4BL list file indicated, and proper configuration set, and also, some test production should be run before request of batch production is done.
Sometimes request are incomplete, G4BL lists files are not on indicated paths, and tests are needed to be run on the grid first. Some exchange is than necessary before full productions. All of this is slowing the productions.

6. Migration from WMS to DIRAC
During the last and this year, on several sites Workload Management System (WMS) service was stopped (outdated).
Because of this, on some sites supporting MICE Virtual Organisation (VO) Computing Elements (CEs) did not take jobs, and production could be done on decreasing number of sites.
The migration from WMS to DIRAC, a successor Workload System has to be done, in order to use all the sites which are supporting MICE VO, and migration had to be concluded till the end of 2017, since WMS will not be operating after that.
The migration was successful one. MC production on the grid using DIRAC submission system was used for all productions since last CM.

7. Productions since last CM
19 new productions, 427 GB in 22,621 files
- Out of 73 productions 1,5 TB in 78,072 files
5 new G4BLs. Each with ~8 GB in ~1000 json files.

Conclusions
Many new MAUS productions and some G4BL productions done since last CM.
Migration from WMS to DIRAC successful
Transfer of big tarball for each productions to RAL castor tape should be done after current data taking. All setups done. No more problems with uploading files to castor.
