Talk Title: Energy Efficient and Reliable GPGPU Architecture
Series: EE598 Seminar Course
Abstract: Graphics Processing Units (GPUs) are initially designed to provide a high performance computing for multimedia applications. Due to the efficiency of their execution model, nowadays GPUs are used to run scientific, medical and financial workloads in addition to the multimedia workloads. In this talk we will explore the opportunities in current GPUs that can be used to support a reliable and power efficient execution without affecting the overall performance of GPUs.
In the first part of the talk we will go through some workloads characterization experiments to explore the available opportunities for reliable and power efficient solutions. In the second part we will introduce two mechanisms based on the explored opportunities. The first mechanism is warped DMR that focuses on designing a reliable execution model in GPUs in order to match with the reliability requirements for the new set of application domains. The second mechanism is warped register file that targets designing a power efficient register file for GPUs in order to mitigate the wasted leakage and the dynamic power caused by the mismatch in applications requirements.
Biography: Mohammad Abdel-Majeed is a 3rd year PhD student in Electrical Engineering department at University of Southern California. He is working under the supervision of Professor Murali Annavaram and his research focuses on the power efficiency in the modern high throughput processors.
Hyeran Jeon is a PhD student in Electrical Engineering department of University of Southern California. She is also a member of SCIP lab led by Professor Murali Annavaram. Her research interest is in architectural support for reliable computing.
