Sun Microsystems has followed through on a promise to release the designs of a second server processor as open-source software.
Sun Microsystems on Tuesday followed through on a promise to release the designs of a second server processor as open-source software.
The design for Niagara 2, formally called the UltraSparc T2 and currently shipping in servers, now is governed by the General Public License (GPL) -- though as with Niagara 1, Sun is using the earlier version 2 of the seminal license.
The overall initiative, called OpenSparc, is geared to increase the relevance of the Sparc family by building academic and engineering expertise around the processor. To that end, Sun also said five universities throughout the US have been designated OpenSparc technology centers of excellence.
The T1 and T2 chips both employ an aggressively multithreaded design that can juggle multiple tasks simultaneously. All major chipmakers are employing this approach, though not as dramatically, in an effort to get more work out of processors now that it's hard to boost them through clock speed improvements.
