The record

Purpose: SourcererCC is a token-based code clone detector for very large code bases and Internet-scale project repositories.
Granularity: It can detect clones between files, methods, statements, or blocks.
Language support: The README says it can detect clones in any language, with tokenizer language settings and file extensions configured by the user.
Similarity threshold: The documented default threshold flags clones at 80% similarity, and the threshold can be changed.
File size bounds: The documented file-level clone detection configuration ignores files below 65 tokens or above 500000 tokens by default.
Parallel processing: The controller splits the detection task across multiple nodes, whose results must be aggregated.
Input preparation: Source code must first be tokenized, and the documented tokenizer accepts configured file extensions and project paths.
VM artifact: The project describes a virtual machine artifact with pre-programmed steps from raw source code to a database with clone mappings and says it is an easy way to get started.
Web tool: The README describes DéjàVu as a supporting web tool for quick and simple clone analysis.
Notable platform limit: The README says the tokenizer's multiprocessing features do not work on Macs with Python versions later than 3.6 and recommends avoiding Mac for this workflow.
Support: The README invites users to contact the project for questions or technical help, including performance tuning for their hardware.
License: The repository identifies its license as GPL-3.0.
