Tera Computer Company

The Tera Computer Company was a manufacturer of <a href="/facts/High-performance_computing/HT9NwGAN">high-performance computing</a> <a href="/facts/Computer_software/RP79lVSW">software</a> and <a href="/facts/Computer_hardware/8jSjsCNv">hardware</a>, founded in 1987 in <a href="/facts/Washington%2c_D.C./enXPK156">Washington, D.C.</a>, and moved 1988 to <a href="/facts/Seattle%2c_Washington/7lYIrCa6">Seattle, Washington</a>, by James Rottsolk and <a href="/facts/Burton_Smith/4F9maqd4">Burton Smith</a>.

It also had no data cache, relying instead on switching between threads for latency tolerance, and used a deeply pipelined memory system to handle many simultaneous requests, with address randomization to avoid memory hot spots.
The company was listed on <a href="/facts/NASDAQ/C6GlcQcB">NASDAQ</a> under the ticker symbol "TERA".
In 1997, Tera Computer went to San Jose, California-based Cadence Design Systems Inc to develop microprocessors for their use in CMOS technology. Unisys manufactured Tera's gallium arsenide CPU.
Upon acquiring the Cray Research division of <a href="/facts/Silicon_Graphics/DKvkrfLX">Silicon Graphics</a> in 2000, the company was renamed to <a href="/facts/Cray/coAlupuy">Cray Inc.</a>
In 2019, Cray Inc. was acquired by <a href="/facts/Hewlett_Packard_Enterprise/d9NbClDt">Hewlett Packard Enterprise</a> for $1.3 billion.
