Cthulhu is a simple server-client-based job scheduler developed in Java; named after H.P. Lovecraft's part-octopus god (because it will be able to manage several machines - get it? : D). It's similar to Batch systems, in that it schedules lists of jobs in cluster environments. It consists of a master binary and a worker binary, which work together to run processing jobs of different kinds (e.g. Feature Extraction (FE), Bash Scripts, FE Result Retrieval, etc.).
