Tutorial Details: Efficient Use of Koronis

Date: Thursday, June 20, 2013, 01:00 pm - 03:00 pm
Location: 575 Walter
Instructor(s): Shuxia Zhang, MSI

Koronis features an SGI® Altix® UV 1000 – a large global shared memory (GSM) system. Its availability has offered unprecedented opportunities for NIH researchers to conduct memory-intensive calculations. At the same time, it poses great computational challenges from the system-memory complexity that, combined with the flexibility in the selection of the number of computing cores, can severely degrade the performance.

This tutorial will help users make efficient use of Koronis and improve the application performance. Topics to be discussed include: 1. The tactics for better use of CPUSET hierarchy. 2. How the queues are structured and how to reduce the queuing time of your jobs. 3. The available file systems and how they can be used for improving the I/O performance of your applications.

Level: Introductory
