DescriptionMany of today’s modeling and simulation applications struggle to achieve good parallel efficiency and performance on current petascale systems. The high discrepancy between a system’s peak performance and the performance that can be achieved by applications is often blamed on the inter-node communications networks on these systems. In truth, internal communications networks represent very large improvements on the inter-node communication networks of even 5 years ago. The limited efficiency seen is chiefly a function of the lack of explicit parallelism exhibited by the underlying algorithms, or utilized by the application codes. More recently, I/O performance has started to play a critical role, so that even if the computational part of a workload can scale to extreme parallel systems at exascale, reading and writing the data associated with it will present a major challenge. It is rarely acknowledged is that, as core-counts have increased, the performance of I/O subsystems have struggled to keep up with computational performance and have, over the past few years, become a key bottleneck on today’s largest systems.
This workshop will:
* Describe the I/O related challenges that both HPC and high performance data analytics (HPDA) face going forward;
* Examine how increasingly complex memory and storage hierarchies, and recent technological innovations such as Intel’s 3D XPointTM non-volatile memory, could have an impact on the I/O challenge; and
* Discuss potential hardware and software solutions for dealing with the extreme volumes of data involved in scientific (and industrial) computing today and in the future
