By opening the UltraSPARC T1 and UltraSPARC T2 source code and specification we hope to create opportunity to create unique solutions built on a proven architecture. One of these areas is Operating Systems ports to these architectures. Through the efforts of Sun Microsystems and the community, the following efforts are shared with the community. The OpenSPARC community would be very open to lending support to other projects that would want to port to UltraSPARC T1 and/or UltraSPARC T2. Below are several operatings systems that support the UltraSPARC T1 and/or UltraSPARC T2 .
Solaris and OpenSolaris
Solaris operating system and operating systems derived from OpenSolaris on UltraSPARC T1. The foundation for Sun systems, Solaris delivers a consistent computing environment from departmental servers up to massive, clustered servers with more than 100 CPUs; designed for multiprocessing and 64-bit computing.
Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public License, the source code for Linux is freely available to everyone. Several distros of Linux are supported on SPARC Hardware.
Ubuntu Supports the UltraSPARC T1 and UltraSPARC T2
