PyPhi can use Redis as a fast in-memory global LRU cache to store MICE objects, reducing the memory load on PyPhi processes.

Install Redis. The redis.conf file provided with PyPhi includes the minimum settings needed to run Redis as an LRU cache:

redis-server /path/to/pyphi/redis.conf

Once the server is running you can enable Redis caching by setting REDIS_CACHE: true in your pyphi_config.yml.

Note: PyPhi currently flushes the connected Redis database at the start of every execution. If you are running Redis for another application be sure PyPhi connects to its own Redis server.
