2. Benchmark (computing) - Wikipedia

   en.wikipedia.org/wiki/Benchmark_(computing)

   Benchmark (computing) A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. [1]

3. Multithreading (computer architecture) - Wikipedia

   en.wikipedia.org/wiki/Multithreading_(computer...

   Multithreading (computer architecture) Appearance. For threads in software, see Thread (computing). A process with two threads of execution, running on a single processor. In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.

4. Cache performance measurement and metric - Wikipedia

   en.wikipedia.org/wiki/Cache_performance...

   The gap between processor speed and main memory speed has grown exponentially. Until 2001–05, CPU speed, as measured by clock frequency, grew annually by 55%, whereas memory speed only grew by 7%. [1] This problem is known as the memory wall. The motivation for a cache and its hierarchy is to bridge this speed gap and overcome the memory wall.

5. Cache prefetching - Wikipedia

   en.wikipedia.org/wiki/Cache_prefetching

   Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...

6. Snappy (compression) - Wikipedia

   en.wikipedia.org/wiki/Snappy_(compression)

   Compression speed is 250 MB/s and decompression speed is 500 MB/s using a single core of a circa 2011 "Westmere" 2.26 GHz Core i7 processor running in 64-bit mode. The compression ratio is 20–100% lower than gzip. [5] Snappy is widely used in Google projects like Bigtable, MapReduce and in compressing data for Google's internal RPC systems.

7. 32-bit computing - Wikipedia

   en.wikipedia.org/wiki/32-bit_computing

   A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.

8. FLOPS - Wikipedia

   en.wikipedia.org/wiki/FLOPS

   Not to be confused with Instructions per second. 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 ]

9. Load (computing) - Wikipedia

   en.wikipedia.org/wiki/Load_(computing)

   In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.
