Now complete: Allinea Software presents at Cray User Group (CUG) 2012
Visit Allinea Software's technical presentations and exhibition
We are silver sponsors of the CUG 2012; one of our team will be in the exhibition area ready to help you discover how our tools can help you. Remember to stop by during the breaks.
As well as exhibiting, our CTO, David Lecomber, will also present two technical papers during the CUG technical program:
- Introduction to Debugging for the Cray Systems
- Accelerated Debugging: Bringing Allinea DDT to OpenACC on the Cray XK6 beyond Petascale
Introduction to Debugging for the Cray Systems
Date: Monday 8:00am - 10:30am
Chair: John Noe (Sandia National Laboratories)
The art of debugging HPC software has come a long way in recent years - and in this tutorial, we will show how Allinea DDT can be used to debug MPI and accelerator code on the Cray XK6. There will be walk-throughs and hands-on opportunities to work with some typical bug scenarios - showing how easily debuggers provide the means of resolving software problems and some of the "tricks of the trade" which will give users experience. There will also be demonstrations of debugging at Petascale and exploring how debuggers can get to grips with software issues in applications at scale.
Accelerated Debugging: Bringing Allinea DDT to OpenACC on the Cray XK6 beyond Petascale
Date: Tuesday 1:00pm - 2:30pm
Technical Session: 7B
Chair: Ashley Barker (ORNL)
The ability to debug at Petascale is now a reality for homogeneous systems such as the Cray XE6, and is a vital part of producing software that works. Developers are using Allinea DDT to debug their MPI codes regularly at Petascale - with an interface that is responsive and intuitive even at this extreme size.
With the arrival of the Cray XK6, applications are changing to involve GPU acceleration and the need for debugging remains - and is greatened by these changes to the core parts of existing software. This paper will discuss the challenges of supporting hybrid systems at scale, and the results of work at Allinea Software to prepare for systems such as Titan, including adding support in Allinea DDT for the OpenACC model provided by the Cray Compiler Environment and for ensuring scalability in hybrid systems.
About the Cray User Group
The conference theme Greengineering the Future reflects the fact that Stuttgart is the capital of Baden-Württemberg, which is the place where most engineering innovations worldwide have been created. Making these innovations turn the world into a greener one is the key challenge of the future. The conference will be held at the center of Stuttgart at the Maritim Hotel from April 29 – May 3 2012.
CUG 2012 will be the forum for Cray users and developers to exchange their expertise, problems, and solutions. Participants will have the opportunity to share ideas and experiences, and meet key members of the Cray team. Social events will allow communicating in a relaxed atmosphere. A visit to the Mercedes Museum gives participants a view of 125 years of automobile development. From cars to stars!
