The Calibrator is a small C program that is supposed to analyze a computer's memory system and extract the following parameters: * number of cache levels * for each cache level: size, linesize, access/miss latency * main memory access latency, number of TLB levels * for each TLB level: capacity, pagesize, TLB miss latency The Calibrator is a by-product of our work on Main-Memory Databases within the Monet project. The Calibrator is freely available for download and usage, but we kindly ask all users to include a reference to the Calibrator's home page whenever they refer to the Calibrator or publish calibration results.
