Sun Microsystems Opens Door for Open Sourcing SPARC Technology - Raises the Temperature on Competition With 'Coolest' Chip in Town

Sun OpenSPARC(TM) Initiative Publishes UltraSPARC(R) Architecture 2005 and

HyperVisor API Specifications, Enabling Greater Customer Choice and Innovation

in Highly-Threaded Environments

    SAN FRANCISCO, Feb. 14 /PRNewswire-FirstCall/ -- Sun Microsystems Inc.
 (Nasdaq:   SUNW - News) announced today at the Open Source Business Conference
 (OSBC) that its OpenSPARC initiative has released the UltraSPARC(R)
 Architecture 2005 and HyperVisor API specifications to help jumpstart the
 porting of Linux, BSD and other operating systems, middleware and applications
 to the UltraSPARC  T1 processor with CoolThreads(TM) technology.  The
 publication of these specifications will broaden the base of users who can
 take advantage of the performance, power and space benefits of the UltraSPARC
 T1 processor's massive throughput. The documentation is available for free
 download at:
     "Sun is making the documentation available to help nurture  the creation
 of a new chip multi-threading community, and to assist companies interested in
 porting operating systems and other applications to the UltraSPARC T1
 processor's threaded environment.  The development community now has the
 information needed to port Linux to the CoolThreads architecture and to take
 full advantage of the chip's multi-threading capabilities.  Sharing UltraSPARC
 T1-based processor source code reflects Sun's continuing commitment to the
 open source development model and to offering customers greater choice.
     "Today we open the door to expanding SPARC onto new platforms and into new
 markets, breaking down barriers to innovation and giving our customers more
 choice," said Jonathan Schwartz, President and Chief Operating Officer, Sun
 Microsystems.  "Having Linux or BSD ports for the UltraSPARC T1 processor will
 greatly expand the SPARC market, giving customers more opportunities to reap
 the benefits of our CoolThreads technology. The OpenSPARC effort is fostering
 a community for SPARC-based, 32 thread innovation that will play a crucial
 role in redefining industry standards in the data center."
     Community Support for OpenSPARC
     Industry guru David Miller is actively working on expanding the UltraSPARC
 T1 onto new operating platforms and applications.
     Kip Macy, the author of the FreeBSD port to the Xen x86 hypervisor, is
 excited about the opportunity to port FreeBSD to a new hypervisor on a new
     "The UltraSPARC T1 processor's approach to throughput computing is a
 refreshing change from other architectures and FreeBSD will one day be able to
 fully exploit the parallelism exposed by the cutting edge processor. The T1 is
 particularly interesting to me because I feel that its price-performance
 should, for the first time, make the UltraSPARC an important participant in
 commodity computing environments." is a free, active, open source community resource that
