MPE – MP Software, main points n YETS 2017/2018: Maintenance work on the LHC Post Mortem System to address recent performance issues. The most likely solution will be to unload the server by migrating historic data to a different physical machine (while maintaining it accessible for the analysis tools). ¨ This has to be done ahead of the start of HWC, i. e. before the end of January. Validation will be done by doing dry Post Mortem dumps. ¨ n LS 2: New version of PM system replacing the current infrastructure. Possibly this will be joined with the NXCLAS (new Logging system). The system has to be ready by mid-end 2019 to allow people to efficiently migrate to the new infrastructure and avoid any delay in the start of IST and commissioning activities. ¨ New version of software layer for LHC quench detection. The system has to be ready by mid-end 2019 to allow Reiner and Co to do an early validation of the DYPQ upgrades and prepare the IST tests. ¨ Massive migration of FESA classes for BIS, SMP, FMCM, . . to comply with the eradication of FESA 2 announced by CO. Again to be ready for all IST and commissioning tests of the respective equipment. ¨ LHC Coordination Meeting, 26/09/2017 MPE-MI, Jan Uythoven 7
