Architecture for Big Data & Machine Learning

Intel Domain Leader : Debbie Marr

Big Data Computing results in huge (and costly) energy consumption. Computing Technology energy is dominated by data movement. The research aims at new paradigms in handling data movements in Big Data environment consisting of minimizing data movement, moving the computing closer to the data, accelerating the computing, and exploiting more effective novel memory technologies.

Research Project Summary:      
This research project will explore break-through performance and energy efficiency for a big data analytics platform addressing four major storage and computation challenges: 

  1. Data movement within/across nodes, and what/where computation should be placed in the storage hierarchy,
  2. Accelerators for Big Data
  3. Application and usage of new memory technologies such as Memristors within and across nodes.
  4. Define a new Prediction Environment based on Semantic Locality and context-based using Reinforcement Learning applicable to Big Data (both as a tool and Apps enhancements.

Research Project Summary:      
Our research objective is to leverage emerging Non-Volatile Memory (NVM) technologies to increase computing throughput without increasing energy consumption. The research is broad and not necessarily related to a specific emerging NVM technology. Previously, we proposed continuous flow multithreading (CFMT), a multithreaded microarchitecture, where multistate registers are embedded in the pipeline to store the states of multiple threads. CFMT increases the performance to energy of the processor by 42% on average. Additionally, we proposed different circuits for computation within memory and for integration with CMOS logic gates. In this research, we plan to develop novel memory-intensive architectures. These architectures are based on integration of emerging NVM with CMOS and include processor microarchitectures, branch predictors, and utilizing emerging NVM at all levels of the memory hierarchy. We plan to develop and design new device models, circuits, and architectures for memory-intensive machines. Additional microarchitectures for multithreaded processors that further enhance the performance/energy ratio will be developed, as well as additional beneficial applications to multistate registers.
