Programming the Xeon Phi | |
Event Type: Tutorial | Time: 8:30AM - 5:00PM | Location: Room 394 | |
The Innovative Technology component of the recently deployed XSEDE Stampede supercomputer at TACC provides access to 8 PetaFlops of computing power in the form of the new Intel Xeon Phi Coprocessor, also known as a MIC. While the MIC is x86 based, hosts its own Linux OS, and is capable of running most user codes with little porting effort, the MIC architecture has significant features that are different from that of present x86 CPUs, and optimal performance requires an understanding of the possible execution models and basic details of the architecture. This tutorial is designed to introduce attendees to the MIC architecture in a practical manner. Multiple lectures and hands-on exercises will be used to acquaint attendees with the MIC platform and explore the different execution modes as well as parallelization and optimization through example testing and reports. | |

VISTech 2014: Visualization Infrastructure and Systems Technology | |
Event Type: Workshops | Time: 9:00AM - 5:30PM | Location: Room 294 | |
Human perception is centered on the ability to process information contained in visible light, and our visual interface is a tremendously powerful data processor. Every day we are inundated with staggering amounts of digital data. For many types of computational research, visualization is the only viable means of extracting information and developing understanding from this data. Integrating our visual capacity with technological capabilities has tremendous potential for transformational science. We seek to explore the intersection between human perception and large-scale visual analysis through the study of visualization interfaces and interactive displays. This rich intersection includes: virtual reality systems, visualization through augmented reality, large scale visualization systems, novel visualization interfaces, high-resolution interfaces, mobile displays, and visualization display middleware. The VISTech workshop will provide a space for experts in the large-scale visualization technology field and users to come together to discuss state-of-the art technologies for visualization and visualization laboratories. | |

Event Type: HPC Interconnections (BE, Undergraduates, Cluster) | Time: 3:30PM - 7:00PM | Location: Room 288/289 | |
The Broader Engagement programming challenge is an opportunity for new programmers and seasoned programmers within the BE program to compete against each other in friendly competition. With multiple levels and multiple languages, there is something for everyone to excel at. You only need your laptop to compete, as a virtual machine will be provided with all the needed software needed. Participants can also use their own software if they prefer. Test your abilities by writing legible code in a timely manner. Top competitors will receive prizes. | |

Experimental Infrastructures for Open Cloud Research | |
Event Type: Birds of a Feather | Time: 12:15PM - 1:15PM | Location: Room 388/389/390 | |
Cloud Computing has emerged as a critical infrastructure for scientific, enterprise, and commercial computing. To support the creation of such infrastructure, there is a need for quality testbeds for development and testing. Commercial companies create their own testbeds, but academic and government cloud researchers don't have access to them. Therefore, funding agencies around the world have or soon will construct an array of new experiment infrastructures for in cloud computing. This BOF will provide a forum for the providers of these experimental infrastructures and their potential users to come together, and form a community of testbeds. | |

A User-Friendly Approach for Tuning Parallel File Operations | |
Event Type: Papers | Time: 2:00PM - 2:30PM | Location: Room 393/394/395 | |
The Lustre file system provides high aggregated I/O bandwidth and is in widespread use throughout the HPC community. Here we report on work (1) developing a model for understanding collective parallel MPI write operations on Lustre, and (2) producing a library that optimizes parallel write performance in a user-friendly way. We note that a system's default stripe count is rarely a good choice for parallel I/O, and that performance depends on a delicate balance between the number of stripes and the actual (not requested) number of collective writers. Unfortunate combinations of these parameters may degrade performance considerably. For the programmer, however, it's all about the stripe count: an informed choice of this single parameter allows MPI to assign writers in a way that achieves near-optimal performance. We offer recommendations for those who wish to tune performance manually and describe the easy-to-use T3PIO library that manages the tuning automatically. | |

Super-R: Supercomputing and R for Data-Intensive Analysis | |
Event Type: Birds of a Feather | Time: 5:30PM - 7:00PM | Location: Room 388/389/390 | |
R has become popular for data analysis in many areas due to its high-level expressiveness and multitude of domain-specific packages. Challenges still remain in developing methods to effectively scale R to the power of supercomputers, and in deploying and enabling access to end users. This year's BOF will focus on usability and provisioning R as an interactive high performance analysis environment within HPC resources. This BOF will consist of a set of short presentations and discussions with audience. The ultimate goal is to help build a community of users and experts interested in applying R to solve data intensive problems. | |

Xeon Phi Users Group: Performance Tuning and Functional Debugging for Xeon Phi | |
Event Type: Birds of a Feather | Time: 5:30PM - 7:00PM | Location: Room 286/287 | |
This BOF will build community among those developing HPC applications for systems incorporating the Intel Xeon Phi many-core processor. Taking advantage of the processor's full capabilities requires tuning and optimizing using programming techniques and tools targeted at a combination of CPUs and the Xeon Phi Coprocessor. Threading, vectorization, memory contiguity and alignment, and data locality may be important for performance. This BOF will combine a few brief presentations sharing insights and best practices with a moderated discussion among all those in attendance. It will close with an invitation to an ongoing discussion through the Intel Xeon Phi Users Group (IXPUG). | |

Drilling Down: Understanding User-Level Activity on Today's Supercomputers with XALT | |
Event Type: Birds of a Feather | Time: 12:15PM - 1:15PM | Location: Room 386/387 | |
Let's talk real, no-kiddin' supercomputer analytics: drilling down to the level of individual batch submissions, users, and binaries. And we're not just targeting performance: we're after everything from which libraries and functions are in demand to preventing the problems that get in the way of successful science. This BoF will bring together those with experience and interest in technologies that can provide this type of job-level insight. To this end, the proposers will show off their new tool named XALT and have a short demo that the attendees can do on their own laptops. | |

HUST14: First International Workshop on HPC User Support Tools | |
Event Type: Birds of a Feather | Time: 3:30AM - 12:00PM | Location: Room 297 | |
Researchers pushing the boundaries of science and technology are an existential reason for supercomputing centres. In order to be productive, they heavily depend on HPC support teams, who in turn often struggle to adequately support the researchers. Nevertheless, recent surveys have pointed out that there is an abundant lack of collaboration between HPC support teams all around the world, even though they are frequently facing very similar problems with respect to providing end users with the tools and services they require. With this workshop we aim to bring together all parties involved, i.e. system administrators, user support team members, tool developers, policy makers and end users, to discuss these issues and bring forward the solutions they have come up with. As such, we want to provide a platform to present tools, share best practices and exchange ideas that help streamline HPC user support. More information: https://ugent.be/hpc/hust14.html
