[LA-SiGMA-TESC] Technologies for Extreme Scale Computing seminar Thursday (3/13)

[Wei P Feinstein]

Hi all,

We will have our weekly seminar at 11:00am-12:00pm on Thursday (3/13) in the Digital Media Center Theatre.  Dr. Jian Tao, a research scientist from CCT, is going to present.

Title: Computational Hierarchy for Engineering Model-Oriented Re-adjustable Applications (CHEMORA)

Abstract:

Starting from a high-level problem description in terms of partial differential equations using abstract tensor notation, the Chemora framework discretizes, optimizes, and generates complete high performance codes for a wide range of compute architectures. Chemora extends the capabilities of the Cactus computational framework, facilitating the usage of large-scale CPU/GPU systems in an efficient manner for complex applications, without low-level code tuning. Chemora achieves parallelism through MPI and multi-threading, combining OpenMP, and CUDA. The discretization is based on higher-order finite differences on multi-block domains. Optimizations include high-level code transformations, efficient loop traversal strategies, dynamically selected data and instruction cache usage strategies, and JIT compilation of GPU code tailored to the problem characteristics.  Chemora's capabilities are demonstrated by simulations of black hole collisions. This problem provides an acid test of the framework, as the Einstein equations contain hundreds of variables and thousands of terms. The development of Chemora is supported by the NSF Early-concept Grants for Exploratory Research (EAGER) program under the award number 1265449 (PI: Steven R. Brandt).

PIZZA AND DRINK WILL BE PROVIDED after the presentation in 1008B DMC.
