Programming GPU Devices using OpenACC Directives on the Cray XK6
March, 6-7  2012
CSCS in Manno

The registration fee is of CHF 150 including the coffee breaks.

Registration and agenda »

Contents

Attendees of this HP2C training event will learn about the Cray XK6 hybrid multi-core and GPU architecture and its programming environment.

They will learn about the OpenACC directives, which were designed to help users develop and port applications to run on heterogeneous systems. They will have an understanding on how to use the Cray Performance tools to identify “hot areas” in the code to focus the use of OpenACC directives. They will have the opportunity to experiment the OpenACC directives with the Cray Compilation Environment (CCE). In addition, they will learn about the Cray scientific libraries for accelerators and will learn and experiment Allinea’s DDT and Cray’s Performance Tools for debugging and performance tuning of heterogeneous applications on the Cray XK6 systems.

Attendees are encouraged to bring in their own applications and codes for the hands-on sessions.  Experts from Cray PE, OpenACC and libsci development and performance tools and Allinea DDT debugger will be present at the meeting for discussions and feedback.  We also invite current users who have their applications running successfully on the Cray XK6 system to present brief user experience talks.

The school will cover topics such as the principles of parallel programming, distributed memory programming with MPI, shared memory programming using OpenMP, hybrid programming with MPI/OpenMP and performance tools for parallel applications, as well as some advanced topics. The purpose of the summer school is to teach programming skills and therefore a large proportion of the course will be dedicated to practical exercises.

A course outline is available on our webpage under “Events” where you will also be able to register for the summer school.

Potential participants are advised to register and make arrangements for accommodation as soon as possible due to the fact that hotels in the Lugano area are very busy during August.

We look forward to seeing you in Lugano!

Registration is 30€. To REGISTER for the Workshop and ISC please click here.

CSCS is pleased to announce the following two courses that will take place in Manno during June.

Fast Parallel I/O on HPC systems – 9-10 June 2011

Improved scalability of parallel computational kernels in modern HPC applications frequently exposes the time taken to access data storage devices as the major continuing bottleneck to further scalability increases. Many applications serialize data output through a single processor, and this limits their ability to take advantage of the full capabilities of the fast storage systems attached to modern HPC machines. This course looks at the capabilities of modern HPC fast storage infrastructure, the filesystems that are designed to make efficient use of this hardware and the most frequently used parallel libraries that allow applications to spread the I/O load across multiple processes and provide good read and write performance on these systems.

CRAY XMT Programming Workshop – 16-17 June 2011

Over the next few months CSCS will introduce the Large-Scale Data Analysis service which will incorporate data staging and storage facilities and a number of complementary computer architectures for data analysis, including a new Cray XMT2 machine. The goal of this course is to familiarize the students with the new Cray XMT architecture and enable them to start programming it for maximum performance. This course will be given by Cray personnel with a vast experience of developing applications on massively multi-threaded architectures.
