SPECIAL JOINT SDI / ISTC-CC / CALCM SEMINAR
DATE: Friday, May 24, 2013
TIME: 10:30 am - 11:30 am
PLACE: CIC - 4th floor (ISTC Panther Hollow Room)
SPEAKER: Chris J. (CJ) Newburn, Intel
TITLE: Discovering Intel Xeon Phi, an Architecture for Discovery
ABSTRACT:
The Intel Xeon Phi coprocessor is fully-capable, yet more parallel and power efficient than traditional CPUs. In this talk, CJ will give an overview of the Xeon Phi architecture and software stack, and then highlight its key characteristics that differentiate it from Intel Xeon and make it a logical basis for future exascale work.
One of the innovative parts of the software stack for Xeon Phi is the compiler and runtime support for offload. CJ will detail this software architecture and show an evaluation of its key performance features using customer workloads and directed tests. As part of that evaluation, CJ will highlight the characteristics of applications that correlate with offloaded performance.
The existence of different architectural families, such as Xeon and Xeon Phi, and of different execution modes, such as offloaded or native execution and symmetric MPI, implies that each offers differentiated value to developers, depending on the characteristics of their applications and the level of investment they're willing to make at parallelization. CJ will also cover how applications can be assessed and tuned to become more suitable for each target and execution model.
BIO:
Chris J. Newburn (CJ) serves as a Performance and Feature Architect for the Many-Integrated Core (MIC) product line at Intel. He enjoys finding and addressing issues across our tools, programming models, and in our microarchitecture, and he focuses on making technology usable. In his 15 years at Intel since getting a Ph.D. from CMU's ECE Department, he's worked as a micro-architect, micro-coder, instruction set architect, and language architect. He's privileged to work on real products that are used to advance basic science and engineering, and ones used by his Mom.
