	UltraSPARC T1 - Wikipedia, the free encyclopedia
		Sun Microsystems' UltraSPARC T1 microprocessor, known until its 14 November 2005 announcement by its development codename "Niagara", is a multithreading, multicore CPU.
		The UltraSPARC T1 was designed from scratch as a multi-threaded, special-purpose processor, and thus introduces a whole new architecture for obtaining high performance.
		One of the limitations of the UltraSPARC T1 design is that a single floating point unit is shared between all 8 cores, making the T1 unsuitable for applications performing a lot of floating point mathematics.

	SPARC - Wikipedia, the free encyclopedia
		As of December 2005 Sun announced their UltraSPARC T1 design will be open sourced.
		The SPARC architecture was heavily influenced by the earlier designs of the RISC I and II from the University of California, Berkeley.
		UltraSPARC Architecture 2005 includes Sun's standard extensions and remains compliant with the full SPARC V9 Level 1 specification.

	Sun Sets Hope On New 'Green' UltraSPARC T1 Chip - The Post Chronicle
		Sun played up the efficiency advantages of the new T1 processors, stating that if the entry-level servers sold in the last three years were replaced with T1-powered machines, it would represent the elimination of more than 11 million tons of carbon dioxide emissions, the equivalent of 1 million SUV automobiles, according to published reports.
		UltraSPARC T1 with "CoolThreads" technology also uses less than 70 watts of power, at a time when most multicore processors including Intel Corp.'s Xeon and IBM's Power processor lines use around 150 watts, according to Sun officials.
		The T1 is the first microprocessor design to build four memory controllers, transferring data between memory and the processing cores to ensure that data is transmitted into the chip as fast as it can be processed, according to Papadopoulos.

	RSA Performance on Sun Fire T2 : Weblog
		UltraSPARC T1 comes with Modular Arithmetic Unit (MAU) per core which can accelerate expensive modular arithmetic operations found in public key crypto algorithms such as RSA, DSA and DH.
		In the single-threaded case, the T1 is able to do 1033.2 1024-bit RSA signs/s, which is very good and similar to what is accomplished by the Opteron: about 1100 signs/s.
		The reason we don't see that much of a speedup in UltraSPARC T1 is because RSA verify requires less computations compared to sign (one modular exponentiation op for verify vs. two modular exponentiation ops for sign) and the overhead of setting up operations for MAU becomes more visible.

		As to the company's (or its CEO's) T1 claims, we must express some doubts, since they offer a prime example of an attempt to change the game (and enhance competitive advantage) by altering the rules, a process Sun was adept at when it stood atop the IT vendor pyramid.
		McNealy's claims about the uniqueness of Sun's plans to open the T1 to developers were off the mark, since they lag IBM's opening of the POWER processor architecture by over a year and a half.
		While Sun guarantees binary compatibility for Solaris on T1 and said Solaris applications will run unmodified on the new servers, the company's VP of scalable systems (David Yen) has been quoted as saying that applications "must be optimized to work well" on T1 systems.

	Sun releases UltraSparc T1 chip
		Sun Microsystems Inc. Monday unveiled its newest microprocessor from the Niagara family, UltraSparc T1, which the company is calling the world's first multi-threaded "eco-friendly" chip.
		Sun said a platform based around UltraSparc T1 will hit the market by the end of the year, and industry sources said the line, featuring boxes code-named "Erie" and "Ontario," could be announced as early as next week.
		UltraSparc T1 is the latest in an increasingly long line of chips promoted by vendors not so much for their performance, but rather the efficiency of their performance, in an attempt to sway customers concerned about skyrocketing energy costs in the data center.

	Enterprise Systems \| Sun’s UltraSPARC T1 Redefines the Rules of the Game
		They’re powered by a single UltraSPARC T1 microprocessor (Sun’s productized name for the former “Niagara” technologies), which is, in turn, populated with eight discrete processor cores running at 1.2 GHz each.
		Insight64’s Brookwood flags the UltraSPARC T1’s lackluster floating point performance (a consequence, he notes, of the fact that all eight cores share a single FPU) and raises questions about its lack of SMP support.
		More importantly, he argues, UltraSPARC T1 has revitalized Sun—something he admits he (among others) wasn’t sure was possible.

	Sun starts hardware push for eight-core UltraSparc T1 - Computerworld
		Sun Microsystems Inc. today put some server hardware around its new UltraSparc T1 processor (see "Sun releases some, not all, Niagara servers") and began its effort in earnest to convince IT managers that the chip's increased performance and low power consumption will reduce their power bills and help curb heating problems.
		While new, low-power chips will help, "a lot of the problem is that the data centers were not designed to tolerate this kind of capacity for heating and cooling," he said.
		The T1 is being sold in two systems: the Sun Fire T1000, which starts at $2,995, will be available in March, and the Sun Fire T2000, which offers "extensive internal redundancy capabilities," starts at $7,795 and is available now.

		Sun plans to unveil the name on Monday as part of an event devoted to the company's emphasis on computing equipment that consumes less power than current technology, a big problem for customers grappling with electricity bills, as well as heating and cooling issues.
		The UltraSparc T1 runs at 1.2GHz and consumes less than 75W running ordinary workloads, said Fadi Azhari, a marketing director for Sun's Scalable Systems group.
		Along with its Sparc models — UltraSparc T1, a successor called Niagara II that can work in multiprocessor servers and Rock — Sun also has embraced Opteron in its "Galaxy" line of x86 servers.

	The UltraSPARC T1 based Sun Fire T2000 Server
		Since december 2005 a Sun Fire T2000 server with a 1GHz UltraSparc T1 "Niagra" processor from Sun Microsystems is installed at the RWTH Aachen Universities Center for Computing and Communication (CCC).
		The UltraSPARC IV (US IV) and the Niagara processor are both able to initiate 8 instructions per cycle, the US IV being a dual core 4-issue superscalar processor and the Niagara with 1 instruction per cycle for each of the eight cores.
		The single-thread performance of the UltraSPARC IV processor running at 1.2 GHz is about 2 -3 times higher than the single-thread performance of the 1 GHz Niagara chip for many of the programs which we looked at so far and which do not execute many floating point operations.

		A breakthrough in microprocessing, the UltraSPARC T1 processor features SPARC-based CoolThreads technology and a revolutionary eight cores -- each having four threads -- for a total of 32 threads that work simultaneously so many tasks are performed in parallel with no waiting.
		UltraSPARC T1 uses lower compute cycles to do the same amount of crypto operations.
		The impact on our environment is real: If half of the entry servers sold in the last three years were replaced with UltraSPARC T1 processors, over 11 million tons of CO2 emissions, or the equivalent of that emitted by about 1,000,000 SUVs, would be eliminated each year.

	» Is Sun's UltraSparc T1 the ' Terminator'? \| Between the Lines \| ZDNet.com (Site not responding. Last check: 2007-11-04)
		Sun has started shipping some systems based on its UltraSparc T1 processor (see the news story) with claims of "blowing away" industry standards for performance, setting seven world record benchmarks and delivering a five-fold performance increase at one-fifth the power consumer versus Dell, HP and IBM systems.
		Now that Sun's new eco-friendly T1 server systems are in play, we can determine whether the T1 is really a Terminator or a harbinger of Sun's exit from the processor business.
		For example, Stephen Shankland's news story reports that IBM isn't convinced that the T1 will gain traction beyond a small low-end market segment, and that HP launched a Niagara (UltraSparc T1) "bashing" Web site.

		Sun is sprinting with the dual-core concept, which doubles the number of cores or "brains" on a processor, speeding performance and saving both space and energy.
		Sun is touting the energy savings and environmental benefits of UltraSparc T1 by calling it "the world's first eco-responsible processor." Sun claims that if every Web server in the world were replaced with half the number of Sun Fire Servers, it would add up to a $14 billion savings in energy costs annually.
		Azhari said UltraSparc T1 servers will be particularly well-suited to fast-growing, Web-based tiers of applications.
