General Project Information

• Leader: Alvaro Simon (CESGA, Spain) and Zdenek Sustr (CESNET, Czech Republic)
• Mailing List: vt-mpi at mailman.egi.eu
• Status: Active
• Start Date: 10/Nov/2011
• End Date:
• Meetings: 1. 12/12/2011 - MPI VT Management meeting

Motivation

Despite a dedicated SA3 activity to support MPI there still seem to be significant issues in uptake and satisfaction amongst the user communities. This VT

• Works with user communities and projects that use MPI resources (e.g. ITER, MAPPER, A&A, etc) to demonstrate that MPI can work successfully in EGI.
• Sets up a VO on EGI with sites committed to support MPI jobs.
• Improve the communication between MPI users and developers of MPI support within EGI SA3.

Output

The VT is expected to produce the following outputs:

• Materials (tutorials, white papers, etc) about successful use cases of MPI on EGI that can be used by new communities to use MPI on EGI.
• An MPI VO that provides:
  • dedicated CPUs for MPI jobs
  • MPI specific test probes can run on all sites using the VO Monitoring services of Ibergrid (EGI-InSPIRE VO Services group)
  • accounting for MPI jobs
  • user support
• Improved communication channels with MPI users
• The above set of resources and feedback to resource centers, user communities and technology providers on how to improve MPI within EGI.

Tasks

• Task 1: MPI documentation: This documentation will be reviewded and we will decide what needs updating or extending.
