The Calibrator is a small C program that is supposed to analyze
a computers (cache-) memory system and extract the following
parameters:
number of cache levels
for each cache level:
its size
its linesize
its access/miss latency
main memory access latency
number of TLB levels
for each TLB level:
its capacity (i.e. number of entries)
the pagesize used
the TLB miss latency

It is also recommended as a load generator for realtime testing in:
