Floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations. [1] For such cases, it is a more accurate measure than measuring instructions per second. [citation needed]
Petascale computing refers to computing systems capable of performing at least 1 quadrillion (10^15) floating-point operations per second (FLOPS).These systems are often called petaflops systems and represent a significant leap from traditional supercomputers in terms of raw performance, enabling them to handle vast datasets and complex computations.
A floating-point unit (FPU), numeric processing unit (NPU), [1] colloquially math coprocessor, is a part of a computer system specially designed to carry out operations on floating-point numbers. [2] Typical operations are addition , subtraction , multiplication , division , and square root .
HPE Frontier at the Oak Ridge Leadership Computing Facility is the world's first exascale supercomputer. Exascale computing refers to computing systems capable of calculating at least 10 18 IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exa FLOPS)"; [1] it is a measure of supercomputer performance.
Adjusted Peak Performance (APP) is a metric introduced by the U.S. Department of Commerce's Bureau of Industry and Security (BIS) to more accurately predict the suitability of a computing system to complex computational problems, specifically those used in simulating nuclear weapons.
Variable-length arithmetic operations are considerably slower than fixed-length format floating-point instructions. When high performance is not a requirement, but high precision is, variable length arithmetic can prove useful, though the actual accuracy of the result may not be known.
In computing, FLOPS (also flops, for FLoating-point Operations Per Second, or flop/s (< this last choice can't be correct, as the / sign means per, so it basically says FLoating-point Operations Per per Second. Makes no sense, on the same level as ATM machine or PIN number.) is a measure of computer performance. My comment is in ().
The arithmetic intensity, also referred to as operational intensity, [3] [7] is the ratio of the work to the memory traffic : [1] = and denotes the number of operations per byte of memory traffic. When the work W {\displaystyle W} is expressed as FLOPs , the resulting arithmetic intensity I {\displaystyle I} will be the ratio of floating point ...
