A single chip within a multiprocessor system needs to verify that the piece of data it is requesting from the main memory is not present in the cache of another chip. With Opteron, each chip is responsible for making sure that data is not found on one of its neighbors, while in other multiprocessor systems, a centralized chip monitors the cache contents of all the processors, Brookwood said.
AMD will have several years to develop Opteron chips for larger systems, and is currently working on that technology, Hester said.
As a partner of both original equipment manufacturers (OEMs) like IBM Corp., and end-user customers, Sanmina is in a unique position to discuss the IT market. The overall market for IT products is improving, but corporations haven't started to reinvest in IT as hoped, Johnson said.
However, at some point, this will change, he said.
"People have to figure out how to remain more competitive, and that will mean increased investment in technology. Companies worry about the productivity of their sales forces, or the efficiency of their supply chain. There's never going to be a permanent pause in trying to become competitive," Johnson said.
