Cray MTA-2

The Cray MTA-2 is a shared-memory MIMD computer marketed by Cray Inc. It is an unusual design based on the Tera computer designed by Tera Computer Company. The original Tera computer (also known as the MTA) turned out to be nearly unmanufacturable due to its aggressive packaging and circuit technology. The MTA-2 was an attempt to correct these problems while maintaining essentially the same processor architecture respun in one silicon ASIC, down from some 26 gallium arsenide ASICs in the original MTA; and while advancing the network design from a 4-D torus topology to a more scalable Cayley graph topology. The name Cray was added to the second version after Tera Computer Company bought the remains of the Cray Research division of Silicon Graphics in 2000 and renamed itself Cray Inc.

The MTA-2 was not a commercial success, with only one moderately-sized 40-processor system ("Boomer") being sold to the United States Naval Research Laboratory in 2002, and one 4-processor system sold to the Electronic Navigation Research Institute (ENRI) in Japan.

MTA 2

MTA 2 also known as MTA Ath-Thania (English: MTA Two) is the second television channel of the MTA International satellite network. It was launched in early 2004. The programmes are broadcast throughout Europe and parts of Africa below the Sahel region. The channel was established under the auspices of Mirza Masroor Ahmad, the spiritual head of the Ahmadiyya Muslim Community. It runs similar programming to its sister channel MTA 1. The programmes covers a wide range of religious matters, particularly those concerning Islam and presents the Ahmadiyya stance to certain issues. MTA 2 is run and voluntarily funded by Ahmadis.
