      VO questionnaire on EMI middleware transition and features

      • Name of the VO:
      • Number of users in the VO:

      1. The EMI project would like to move from gLite 3.1 to gLite 3.2 and gradually replace all the 3.1 components with their respective 3.2 version. The transition of gLite grid sites from gLite 3.1 to gLite 3.2 implies an update from Scientific Linux 4 to Scientific Linux 5 on those sites that are still using version 4 of the operating system. Because of the operation system update, grid applications that use dynamically linked shared libraries may need to be recompiled. Do you see any issue with the recompilation of any of the grid applications of your VO?
      2. gLite 3.2 includes CREAM CE, but not LCG-CE service for job execution. Although the two services should be identical for users' jobs, given that the jobs are submitted through Workload Management Service (WMS), do you see the replacement of LCG-CEs with CREAM CEs as an issue?
      3. The European Middleware Initiative project (EMI) is collecting requirements to define the development plans for the ARC, gLite and UNICORE middleware stacks for the first year of EMI. (planned release in April 2011) EMI year 1 developments focus on service enhancements (security, consolidation of services and libraries, usability) not on adding completely new functionalities. The EGI user community is expected to provide input to this plan. Please list and explain what enhancements your VO would like to see in the new middleware release.
