A well-known strategy to increase power efficiency consists of incorporating computing accelerators to the system architecture. Currently, many HPC systems include GPUs, but future systems will likely use a larger variety of accelerators: FPGAs, wavefront arrays of fixed-point units for AI, and ultimately, quantum accelerators. However, the average utilization of GPUs in current HPC systems is quite low, and more specialized accelerators are likely to exhibit even lower utilizations.<\/p>\n<p>In this talk, we present a technique to drastically increase the utilization of computing accelerators. It consists of a combination of virtualizing those accelerators to enable concurrent access from different application threads, and providing support for remote access through the system&#8217;s high-speed interconnect. The result is a shared pool of virtualized accelerators that will increase resource utilization, application execution speed, and system throughput while reducing energy consumption. A key component to efficiently implement remote accelerator access is a high-speed interconnection network.<\/p>\n<p>In this talk, we will present performance results for a particular implementation of this architectural innovation, based on enabling access to remote nVIDIA GPUs through an InfiniBand network for unmodified CUDA-accelerated applications. We will also introduce some alternative approaches to implement remote access to accelerators as well as some enhancements for this class of techniques.<\/p>\n<p><strong>11:00 &#8211; 11:30 &#8211; Coffee Break<\/strong><\/p>\n<p><strong>11:30 &#8211; 13:00 &#8211; Congestion Management for Current and Future Interconnection Networks: Challenges and Solutions<br \/>\n<\/strong><em><a href=\"http:\/\/hipineb.i3a.info\/summerschool2017\/speakers\/#pedroj\">Pedro Javier Garcia<\/a>, University of Castilla-La Mancha (UCLM), Spain.<\/em><\/p>\n<p><span style=\"text-decoration: underline;\"><em>Abstract<\/em><\/span>:\u00a0Congestion appears in interconnection networks when intense traffic clogs internal paths, thus slowing down traffic and degrading network performance.

Technology constraints prohibit a reversal of this trend, and the still unsatisfied need for more computing power has led to a pervasive use of accelerators to speed up computations. In spite of this pervasive use, they are typically supervised by general-purpose CPUS, which results in frequent control flow switches and data transfers as CPUs are responsible for communication tasks. This talk will shortly introduce the current state-of-the-art for accelerator-centric communication, and review our observations and insights when experimenting with accelerators sourcing and sinking network traffic. We will discuss current options and limitations, as well as implications on interconnection networks and tool stacks like MPI. In particular, we will learn why specialized processors require specialized communication models. Finally, the talk will offer some opinions on anticipated research problems.<\/p>\n<hr \/>\n<h4><strong>Tuesday, July 11<\/strong><\/h4>\n<p>Room: <em>Salon de Actos ESII<\/em><\/p>\n<p><strong>9:00 &#8211; 10:30 &#8211; Efficient integration of distributed applications with high performance I\/O technologies<br \/>\n<\/strong><em><a href=\"http:\/\/hipineb.i3a.info\/summerschool2017\/speakers\/#bernard\">Bernard Metzler<\/a>, IBM Zurich Research Laboratory, Zurich, Switzerland.<\/em><\/p>\n<p><em><span style=\"text-decoration: underline;\">Abstract<\/span><\/em>:\u00a0Recent years have seen an unprecedented, rapid development of both network and storage\u00a0technologies.
