The Elbrus (Russian: Эльбрус) is a line of Soviet and Russian computer systems developed by Lebedev Institute of Precision Mechanics and Computer Engineering. In 1992 a spin-off company Moscow Center of SPARC Technologies (MCST) was created and continued development.

These computers are used in the space program, nuclear weapons research, and defense systems.

MCST develops microprocessors based on 2 different instruction set architecture (ISA): Elbrus and SPARC

  • Elbrus 1 (1973) was the fourth generation Soviet computer, developed by Vsevolod Burtsev. Implements tag-based architecture and ALGOL as system language like the Burroughs large systems. A side development was an update of the 1965 BESM-6 as Elbrus-1K2.
  • Elbrus 2 (1977) was a 10-processor computer, considered the first Soviet supercomputer, with superscalar RISC processors. Re-implementation of the Elbrus 1 architecture with faster ECL chips.
  • Elbrus 3 (1986) was a 16-processor computer developed by Boris Babaian. Differing completely from the architecture of both Elbrus 1 and Elbrus 2, it employed a VLIW architecture.
  • Elbrus-90micro (1998-2010) is a computer line based on SPARC instruction set architecture (ISA) microprocessors: MCST R80, R150, R500, R500S and MCST-4R working at 80, 150, 500 and 1000 MHz.
  • Elbrus-3M1 (2005) is a 2-processor computer based on Elbrus 2000 microprocessor employing VLIW architecture working at 300 MHz. It is a further development of the Elbrus 3 (1986).
  • Elbrus МВ3S1/C (2009) is a ccNUMA 4-processor computer based on Elbrus-S microprocessor working at 500 MHz.
  • Elbrus 4S (2014) working at 800Mhz, with capacity to calculate 50GFlops. [1]
  • Elbrus 8S (2014-2015) working at 1300Mhz, with capacity to calculate >200GFlops.
  • Elbrus 16S (2018) with capacity to calculate >1TFlops.
