Mr Bernard CHAMBON (CC-IN2P3)


I will give a status report of TReqS, a software companion of HPSS, the HSM we are using at the CC-IN2P3. TReqS, which stands for Tape Requests Scheduler, is intended to provide regulation and optimization of the staging requests to HPSS. TReqS is used at the CC-IN2P3 for several years now from DCACHE and XROOTD, but since fall 2015, we have started a full rewrite of the software, based on a new architecture and implementation with, as main guideline, stability, scalability, new features but also configurable and portable software. In this presentation I will focus on the benefit of the new version so called TReqS-2, the current status of development (server and client) and the plan for the next months (aim of deployment of production instance for 2016/Q3)
