ICL’s mission is to establish and maintain the University of Tennessee as a world leader in advanced scientific and high performance computing through research, education, and collaboration. 4 ICL’s founder, Dr. Jack Dongarra, established the lab in 1989 when he received a dual appointment as a Distinguished Professor at UTK and as a Distinguished Scientist at Oak Ridge National Laboratory. Since then, ICL has grown into an internationally recognized research laboratory, specializing in Numerical Linear Algebra, Distributed Computing, and Performance Evaluation and Benchmarking. The lab now employs nearly forty researchers, students, and staff, and has earned many accolades, including four R&D100 awards. 1989 5 2014 HIGHLIGHTS For ICL, 2014 marks the 25th year of conducting innovative research in high performance computing and cyberinfrastructure, and the lab made significant contributions to the HPC community during the past year. The sections below illustrate ICL’s commitment to excellence, and set the bar for continued progress in our areas of research. For years, ICL has been recognized by industry as a leader in information technology research. Vendors like NVIDIA and Intel regularly collaborate INDUSTRY EXCELLENCE with the lab’s research scientists, exchanging hardware and expertise, in an effort to improve both the hardware and software used in their products. These collaborations have led to very close working relationships and recognition of ICL’s efforts among vendors. The Intel Parallel Computing Center (IPCC) program is comprised of universities, institutions, and labs that are leaders in their field, focusing on modernizing applications to increase parallelism and scalability through optimizations that leverage cores, caches, threads, and vector capabilities of microprocessors and coprocessors. The objective of the Innovative Computing Laboratory’s IPCC is the development and optimization of numerical linear algebra libraries and technologies for applications, while tackling current challenges in heterogeneous Intel® Xeon Phi™ coprocessor- based High Performance Computing. In collaboration with Intel’s MKL team, the IPCC at ICL will modernize the popular LAPACK and ScaLAPACK libraries to run efficiently on current and future manycore architectures, and

  • Investigations of Various HPC Benchmarks to Determine Supercomputer Performance Efficiency and Balance
    Investigations of Various HPC Benchmarks to Determine Supercomputer Performance Efficiency and Balance Wilson Lisan August 24, 2018 MSc in High Performance Computing The University of Edinburgh Year of Presentation: 2018 Abstract This dissertation project is based on participation in the Student Cluster Competition (SCC) at the International Supercomputing Conference (ISC) 2018 in Frankfurt, Germany as part of a four-member Team EPCC from The University of Edinburgh. There are two main projects which are the team-based project and a personal project. The team-based project focuses on the optimisations and tweaks of the HPL, HPCG, and HPCC benchmarks to meet the competition requirements. At the competition, Team EPCC suffered with hardware issues that shaped the cluster into an asymmetrical system with mixed hardware. Unthinkable and extreme methods were carried out to tune the performance and successfully drove the cluster back to its ideal performance. The personal project focuses on testing the SCC benchmarks to evaluate the performance efficiency and system balance at several HPC systems. HPCG fraction of peak over HPL ratio was used to determine the system performance efficiency from its peak and actual performance. It was analysed through HPCC benchmark that the fraction of peak ratio could determine the memory and network balance over the processor or GPU raw performance as well as the possibility of the memory or network bottleneck part.

Date : Abstract This project work confronts the issue of bringing high performance computing (HPC) education to those who do not have access to a dedicated clustering en- vironment in an easy, fully-functional, inexpensive manner through the use of normal old PCs, fast Ethernet and free and open source softwares like Linux, MPICH, Torque, Maui etc. Many undergraduate institutions in India do not have the facilities, time, or money to purchase hardware, maintain user accounts, configure software components, and keep ahead of the latest security advisories for a dedicated clustering environment. The projects primary goal is to provide an instantaneous, distributed computing environment. A consequence of provid- ing such an environment is the ability to promote the education of high perfor- mance computing issues at the undergraduate level through the ability to turn an ordinary off the shelf networked computers into a non-invasive, fully-functional cluster.

  • Design and Implementation of the HPC Challenge
    Design and Implementation of the November 2006 A HPC Challenge Benchmark Suite Piotr Luszczek, University of Tennessee Jack Dongarra, University of Tennessee, Oak Ridge National Laboratory Jeremy Kepner, MIT Lincoln Lab Introduction The HPCC benchmark suite was initially developed for the DARPA's HPCS program 1 to provide a set of standardized hardware probes based on commonly occurring computational software kernels. The HPCS program has initiated a fundamental reassessment of how we define and measure performance, programmability, portability, robustness and, ultimately, productivity in the high-end domain. Consequently, the suite was aimed to both provide conceptual expression of the underlying computation as well as be applicable to a broad spectrum of computational science fields. Clearly, a number of compromises must have lead to the current form of the suite given such a broad scope of design requirements. HPCC was designed to approximately bound computations of high and low spatial and temporal locality (see Figure 1 which gives the conceptual design space for the HPCC component tests). In addition, because the HPCC tests consist of simple mathematical operations, this provides a unique opportunity to look at language and parallel programming model issues. As such, the benchmark is to serve both the system user and designer communities 2. Finally, Figure 2 shows a generic memory subsystem and how each level of the hierarchy is tested by the HPCC software and what are the design goals of the future HPCS system - these are the projected target performance numbers that are to come out of the wining HPCS vendor designs.
