Olukotun was talking with people running data centers in 2000 and understood the problem of those centers running out of power and space. Olukotun believed that multiple processors on a chip in conjunction with multi-threading could resolve those problems. kotun searched for venture capital support, on the basis that a new architecture could lead to a 10x performance increase in server processing capabilities. Venture capitalists introduced Olukotun to microprocessor architect Les Kohn, who designed microprocessors for Sun and Intel.

Another meeting with venture capitalists was scheduled on September 11, 2001. The meeting in New York City was interrupted by the terrorist attack on the World Trade Center, but resumed in a hotel 2 days later. Available capital for funding the server company had vanished, as the economy started to dup into a new recession in 2001.

Hetherington wrote memos to Mike Splain, CTO of the Processor group at Sun, encouraging technology acquisition of Afara Websystems. Hetherington became Chief Architect for Horizontal Systems at Sun, which develops and sells servers for data centers and Web systems.

The search for venture capital continued, since creating a server company requires substantial resources, but there was little available during the recession following 9/11. Afara began negotiations with Sun Microsystems, and the acquisition was consummated in July 2002. This new acquisition fell under the umbrella of Fred DeSantis, the vice president of engineering for horizontal systems at Sun.

Contributions and impact

The project included many technology contributions among Linux, Solaris and SPARC. The Afara CPU used a SPARC port of Debian Linux initially. Debian Linux contributions to Afara Websystem's former CPU architecture continued to grow, including commercial support for Ubuntu

 similar to that of Debian Linux.

The new CPU architecture of Afara Websystems, which became known as "Niagara", had enough merit to cause a competing internal Sun project under DeSantis' organization, called "Honeybee", to be canceled.

Pressure was placed on the computing industry to add cores and threads. While competing microprocessor vendors were designing dual-core chips with two dual-threads per core, the original "Niagara" architecture was a more radical design: an eight core processor with four threads per core.

For web serving loads, Sun had catapulted to become the uncontested fastest single processor on the planet in December 2005, performing 7x faster than the closest Intel server, and has been consistently the highest throughput web server, with the closest competition being 2x-3x slower (socket to socket comparison) as of mid-2009.

 announced its intention to acquire Sun in April 2009, a deal which closed in January 2010. By the end of 2010, market competitors started to release similar products with multiple cores, a less radical approach to threading, but with similar performance characteristics. Oracle continued the radical approach of the original Afara SPARC architecture (large numbers of threads per large number of simple cores) with the release of the SPARC T3 processor in September 2010 - the first 16 core commodity central processing unit, yielding another top performance benchmark, but only by a slim margin.

Olokotun returned to Stanford University to head its "Pervasive Parallelism Lab" in 2008, to help shape the future of software, as he did with hardware.
