The Tera Computer Company was a manufacturer of high-performance computing software and hardware, founded in 1987 in Washington, D.C., and moved 1988 to Seattle, Washington, by James Rottsolk and Burton Smith.[http://www.cray.com/About/History.aspx Cray Inc., History] {{Webarchive|url=https://web.archive.org/web/20140712100729/http://www.cray.com/About/History.aspx |date=2014-07-12 }} The company's first supercomputer product, named MTA, featured interleaved multi-threading, i.e. a barrel processor. 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.{{cite web|year=1999|title=Multi-processor Performance on the Tera MTA|url=http://cseweb.ucsd.edu/~carter/Papers/tera2.html|url-status=dead|archiveurl=https://web.archive.org/web/20120222015429/http://cseweb.ucsd.edu/~carter/Papers/tera2.html|archivedate=2012-02-22}}

The company was listed on NASDAQ under the ticker symbol "TERA".https://www.sdsc.edu/News%20Items/PR042798.html

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.https://www.techmonitor.ai/technology/tera_goes_to_cadence_for_help_with_cmos_supercomputer_chip_1/

Upon acquiring the Cray Research division of Silicon Graphics in 2000, the company was renamed to Cray Inc.{{cite news |year=2000 |title=Supercomputer maker to buy Cray, change name|url=http://news.cnet.com/2100-1001-237517.html |work=cnet news}}https://www.eetimes.com/tera-computer-buys-cray-from-sgi-readies-cmos-processors/

In 2019, Cray Inc. was acquired by Hewlett Packard Enterprise for $1.3 billion.{{cite web |last1=Miller |first1=Ron |title=HPE is buying Cray for $1.3 billion |url=https://techcrunch.com/2019/05/17/hpe-is-buying-cray-for-1-3-billion/ |publisher=TechCrunch |access-date=2025-04-06 |date=2019-05-17}}
