KISTI Cray T3E-900

128-processor Cray T3E-900 (DEC Alpha EV5 450 MHz, 3-D torus, UNICOS) filed by TOP500 under the KISTI Supercomputing Center, Rmax 79.59 and Rpeak 115.2 GFlop/s on the system page (the per-edition table shows 69.3 GFlop/s in June and November 1997 and 77.52 in June 1998). It first appeared at rank 33 in June 1997 and last at rank 52 in June 1998 (https://www.top500.org/system/171149/). HPCwire's 28 June 1997 item reports that the Systems Engineering Research Institute (SERI) had installed a 128-processor T3E-900 with 16 GB of memory and peak performance above 100 GFlop/s, to supplement the institute's existing Cray C916 and J916 systems used by more than 400 Korean researchers, with weather, environment and computational chemistry as first target applications. The same item quotes a 1.8 teraflops figure that belongs to the T3E-900 product family at full scale, not to this machine. SERI is the predecessor of today's KISTI (KORDIC was set up in 1993 and the institutes merged into KISTI in 2001), which is why TOP500 attributes the machine to KISTI; the older vector machine is kisti-cray-ymp-c916. TOP500 lists a further KISTI T3E900 entry with 132 cores (Rmax 82.1 GFlop/s, listed from 1999 to June 2001, https://www.top500.org/system/171150/), which looks like the same installation after an upgrade and is not separately modelled here. The shutdown date is unknown, so status is held as of the last list appearance.
