mimircache: a cache trace analysis platform

Release v0.0.2.83.

Welcome to the documentation of mimircache, a Python3 cache trace analysis platform.

The power of mimircache:
>>> import mimircache as m
>>> c = m.cachecow()
>>> c.vscsi("trace.vscsi")      # find this data under data folder, other type of data supported too
>>> print(c.stat())
>>> print(c.get_reuse_distance())
[-1 -1 -1 -1 -1 -1 11 7 11 8 8 8 -1 8]
>>> print(c.get_hit_ratio_dict("LRU", cache_size=20))
{0: 0.0, 1: 0.025256428270338627, 2: 0.031684698608964453, ... 20: 0.07794716875087819}
>>> c.plotHRCs(["LRU", "LFU", "Optimal"])
>>> c.heatmap('r', "hit_ratio_start_time_end_time", time_interval=10000000)

An example of hit ratio curve plot and hit ratio heatmap.

Supported Features

  • Cache replacement algorithms simulation and trace visualization.
  • A variety of cache replacement algorithms support, including LRU, LFU, MRU, FIFO, Clock, Random, ARC, SLRU, optimal and etc.
  • Hit/miss ratio curve(HRC/MRC) plotting.
  • Efficient reuse distance calculation for LRU.
  • Heatmap plotting for visulizing hit/miss ratio change over time, average reuse distance over time, etc.
  • Reuse distance distribution plotting.
  • Cache replacement algorithm comparison.

Customization

Now you can customize mimircache to fit your own need, you can

  • provide your own cache reader for reading your special cache trace files.
  • write your own profiling method for different cache replacement algorithms.
  • write a middleware for sampling your cache traces for analysis.
