Low Order Moments: https://software.intel.com/en-us/node/599561
Our goal is to parse & process this crime data and to add more meaning to said data. Using various parallel techniques taught in the course and comparing them via the DAAL library.
Introduction
DAAL is a C++ & Java / Scala library for data analytics. It's similar to MKL with some differences:
- MKL focuses on computation. DAAL focuses on the entire data flow (aquisition, transformation, processing).
- Optimized for all kinds of Intel based devices (from data center to home computers)
DAAL supports 3 processing modes
- Offline Processing (Batch) - Data can fit in memory, data can be processed all at once.
- Online Processing (Streaming) - Data is too big for memory, DAAL processes the data in chunks and combine the partial results for the final result.
- Distributed processing - Distributes data processing. DAAL has not bound the communication method and leaves it to the developer (Hadoop, Spark, MPI etc).
