It is this kind of hazy thinking and the lack of real data that justifies my belief that future megaflops
will come from today's megamergers.
Incorporating more than 250 megaflops
of processing power makes it possible to bring the visual and robotic frames of reference into precise registration - a key element in giving the surgeon a sense of immersion in his work.
--LAMf: The best megaflop rate for the algorithm (corresponding to LABlk).
--CMf: The best megaflop rate for the compiler-derived algorithm (corresponding to CBlk).
1988] can achieve 388 megaflops. The RMA primitive SHMEM_PUT can achieve 0.5-2/[micro]s overhead with 500MB/sec.
For sparse LU, since our approach uses a static symbolic factorization which overestimates computation, we only list the megaflops performance.
Absolute Performance (megaflops) for Sparse LU with Partial Pivoting
Critical to this capability are high-performance three-dimensional graphics workstations with multiple scalar processors having total floating-point power of hundreds of megaflops
; operating systems that support regularly scheduled preemptive lightweight threads, so that processes are reliably and regularly scheduled; and very large (more than 10 gigabytes) physical memory capability.
Each processing unit is controlled by an Intel 80286 microprocessor and contains two 16-Mhz Weitek WTL3364 chips, each capable of 32 megaflops
. The machine, which is 8 feet high and 12 feet wide, contains 64 MB of 45 nanosecond static memory and consumes 30 kilowatts of electrical power.
Such machines are based on Intel's 80860 microprocessor, for example, which operates at 40 Mhz and delivers roughly 10 megaflops on the Linpack benchmark.
In 1988 the prize went to the Long Range Global Weather Modelling Program at NCAR, which was parallelized manually and operates at over 400 megaflops (versus a peak of 840 megaflops) on the Cray 416.
Polygon throughput, point transformations, and numbers of vectors per second provide no more relevance than MIPS or Megaflops
do for determining the throughput of an application.
