Cray spoke at Jan. 1994 Petaflops Workshop
Cray 4 projected at $80K/Gflops, $20K in 1998 sans memory (Mp) .67 cost decr/yr; 41% flops incr/yr
1 Tflops = $20M processor + $30M Mp 1 Gflops requires 1 Gwords/sec of BW
SIMD $12M = 2M x $6/1-bit processors … in 1998 this is 32M for 1 Tflops at $50M
Projected a petaflops in 20 years… not 10!
