Microsoft was unavailable for immediate comment, but IBM said it was taking a close look at the alliance.
"We were invited (to join), and we're currently evaluating the goals and mission of the organization and will make a decision at a later date," and IBM spokesman said.
EGA President Donald Deutsch said the consortium is open and vendor neutral, and any company not yet a member can join at any time. "You pay your money, you take your place at the table," he said.
Within academic and research centers, grid computing is an architecture for sharing processing resources across a network, so that all machines function as one large supercomputer. Enterprise vendors are building technology to extend that concept into corporate computing environments, so coompanies can allocate computer power to business processes on an as-needed basis. The end result would be a more efficient use of computing resources.
The EGA board, comprised of the members listed above, as well as NEC and Network Appliance, have approved five working groups, which will each take up a different component of grid computing. Those areas include reference models, component provisioning, data provisioning, utility accounting and metrics, and security, Deutsch said.
