MuL is designed for flexibility. Towards the south it can support multiple south-bound api. Whereas towards the north, it interfaces to applications via a ML-API and RESTful NB-API. Applications using ML-API has the option of being hosted inline the same process address space as MuL core to execute in-context and gain maximum performance.With the SDKs that come with MuL, the app developer or the app itself need not know how and where they are running. The multi-threaded core is optimized using subtle cache-aware programming to get the max mileage especially from Intel CPUs.
