ASCI Red
ASCI Red , also ASCI Option Red or Janus , was a supercomputer installed at Sandia National Laboratories since 1997 . Between June 1997 and June 2000 it headed the TOP500 list of the fastest computer systems . ASCI Red was shut down in September 2005.
The system was developed in collaboration between Intel and Sandia National Laboratories as part of the Advanced Simulation and Computing Program to simulate nuclear weapon explosions . The lead developer was William Camp .
construction
The ASCI Red was a multiple instruction multiple data architecture-based system of originally 9152 Pentium Pro processors clocked at 200 MHz . These were later replaced by 9298 Pentium II OverDrive processors, each clocked at 333 MHz.
Furthermore, the system had 1212 gigabytes of distributed main memory and 12.5 terabytes of hard disk space.
Operating systems
The operating systems used were the Teraflops OS , developed by Intel and based on OSF UNIX , and the Cougar system developed by Sandia, based on the SUNMOS kernel , which each ran on their own partitions . Teraflops OS was mainly used for configuration, administration and development. The actual calculations were carried out under the more efficient Cougar operating system , which also managed the memory distribution.
power
The ASCI Red was the first supercomputer in the MP LINPACK - Benchmark a performance of more than one TFLOPS reached. After upgrading to Pentium II overdrive processors, it achieved over two TFLOPS.
