The average efficiency of computers on the Green500 list increased 10%, from 98 MFlops per watt to 108 MFlops per watt, according to Green500.
However, the number of floating point operations required for this algorithm becomes prohibitive even at sustained flop rates of several hundred Mflops (million flops per second) to a few Gflops (billion flops per second).
1 Total Mflops using LAM Class W Class A Class B procs FE GE FE GE FE GE 1 47.
Based upon a 6700-class digital signal processor from Texas Instruments, it is capable of 900 MFLOPS (million floating-point operations per second) performance at a Single Event Upset (SEU) rate of 1E-4 unrecoverable errors/day using only 5-7 Watts of power.
The core extends floating point performance to 50 MFLOPS, a 50 percent improvement over previous versions.
Compared to the previous-generation 120MHz SH7261, the new 200MHz SH7263 microcontrollers deliver about 70 percent more speed, achieving 480 MIPS (million instructions per second) and 400 MFLOPS (mega floating-point number operations per second) performance.
Starting at 319 MFLOPS per dollar, the SHARC family makes floating-point processing economical for more applications.
Running 100,000 equations in an FMS test of full complex nonsymmetric matrices, a 16-processor SGI Altix 350 system averaged 68,371 MFLOPS (million floating-point operations per second) for 11 hours, a result that easily outpaces most high-performance UNIX(R) servers in use today.
For example, at 80MHz, the device achieves 192 million instructions per second (MIPS), 160 mega floating point operations per second (MFLOPS) and at 120MHz, it achieves 288 MIPS, 240 MFLOPS.
This new DSP provides 1800 MFLOPS (Million Floating-Point Operations Per Second) for high-performance signal-processing applications that need the precision and dynamic range offered by floating-point calculations.
2, has expanded its high performance computing facility to over 200 Peak Mflops, with 64 Gbytes of memory and 1.
