In the particular case of MATMUL on a RS/6000 F50, we have achieved fully compliant Java performance in excess of 500
Mflops.
3) processing per unit area of board space, another critical military driver in space-constrained applications, attains 20-50
MFLOPS per [in..sup.2] of board space in current-generation chips; this exceeds the capacity of popular reduced instruction set computers (RISCs) and CISCs by 10-50 times
From the POWERstation 320 to the POWERserver 950, computing performances range from 9.2 to 25.2
MFLOPS (29.5 to 56 MIPS), onboard RAM options go from 8MB to 512MB, and internal fixed-disk storage is from 160MB to nearly 12GB (gigabytes).
While it is routine today to find computer processors capable of computing hundreds of
Mflops to even Gflop performance on computational kernels, delivering sustained peak performance to solve the problems of large-scale application codes remains a challenge for hardware and software developers.
Each node has a peak performance of 25 VAX MIPS and 10 double-precision
MFLOPS. Cache coherence within a cluster is maintained at the level of 16-byte lines via a bus-based snoopy protocol.
The 4D-MP graphics superworkstation: Computing + graphics = 40 mips + 40
mflops + 100,000 lighted polygons per second.
Early metrics for quantizing microprocessor performance include MIPS and
MFLOPS. "MIPS," million instructions per second, refers to the average number of machine language instructions that a computer can perform in 1 sec.
This code ran on the NCube at about 1.5 GFLOPS; by comparison a highly vectorized version of ZEPHYR-3D runs at about 220
MFLOPS on a single Gray Y-MP processor.
Whetsone, Dhrystone, Linpack, SPEC benchmark suite,
mflops, and mips are all names to measure how fast a computer runs a program.
Floating point performance: 1.4
Mflops. Main memory: 8-16 MB RAM.
Table 7.1 and 7.2 give the total
Mflops for the NAS benchmarks using LAM, and MPICH and MVICH respectively.
