JRA1.1 - Process System: EMI Compute Interface Evolution


The purpose of establishing this system is to setup a process that gives technical direction to the development and maintenance of EMI compute interfaces. It also represents a crucial part of a greater EMI architectural roadmap.


A short system view aout the process is as follows:

  • Middleware proprietary interfaces (gLite CREAM, UNICORE Atomic Services, ARC Proprietary Interface): Used in production
  • OGSA-BES standard adoptions (UNICORE OGSA-BES, ARC A-REX): Used in production & open standard
  • EMI-ES adoption: Specification to be created within EMI (target in 2010)
  • PGI-Compute adoption: Agreements on specifications necessary (target in 2011), specification potentially influenced by EMI-ES specification

Affected JRA1 Tasks

  • Compute task: proprietary middleware interfaces and EMI-ES interface
  • Standardization task: OGSA-BES and PGI-Compute


  • How many compute interfaces we have to support and maintain
  • TBD: Follow-up ARC proprietary interface name of component (Morris, Balazs)

Process Tracking

  • 2010-08-03 - Morris: Raised issue at PTB that we need a technical direction for the compute interface evolution to present a consistent picture to projects outside of EMI
  • 2010-08-03 - Morris: Process system send around for receiving comments from PTB and as material for future discussions
