A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
For example, one can interpret a load average of "1.73 0.60 7.98" on a single-CPU system as: During the last minute, the system was overloaded by 73% on average (1.73 runnable processes, so that 0.73 processes had to wait for a turn for a single CPU system on average). During the last 5 minutes, the CPU was idling 40% of the time, on average.
Miss rate: 0.01 – 1% (20–40% for sparse/graph applications) The average effective memory cycle rate is defined as + + cycles, where is the number of cycles required for a memory read, is the miss rate, and is the hit time in cycles
Released to the market in 2014, [2] [3] [4] it is a variant of dynamic random-access memory (DRAM), some of which have been in use since the early 1970s, [5] and a higher-speed successor to the DDR2 and DDR3 technologies.
