A Performance Tool for Tomorrow’s Supercomputers and Applications
Minimal Metrics has partnered with Sandia National Laboratory to build a performance tool for tomorrow’s Exascale-class supercomputers – and to help inform their design. The system has its roots in a prototype first developed by Philip and colleagues at the Parallel Dator Centrum at the Royal Institute of Technology in Stockholm Sweden. It is a set of software designed to optimize the entire HPC software and hardware ecosystem of an institution. It is capable of analyzing individual HPC applications and their threads of execution as well as entire workloads, groups, users and multiple disjoint systems. It accomplishes this by integrating the best-of-breed dashboarding and visualization methodologies with state-of-the-art performance data collection. detailed performance metrics from the underlying architecture, including memory bandwidth, memory hierarchy behavior and latencies, vectorization, hardware resource utilization, computational intensity and instruction mix are provided. The system is able to identify issues of on and off-node scaling, including message passing performance, load-imbalance, false-sharing, and…
MM tunes the SPEC benchmarks for a brand new architecture with Reservoir Labs
Here at Minimal Metrics our customers are often our friends – and we have lots of them around the world. Among our favorite people to work with are the brilliant people over at Reservoir Labs, makers of R-Scope among other neat bits of technology. Reservoir also has extensive compiler development expertise. When tasked with optimizing the SPEC CPU benchmarks for a brand new 64-bit multicore (non-Intel) processor, they reached out to the Minimal Metrics crew for guidance. The SPEC benchmarks are tricky animals, solely because one cannot modify the source code to improve its performance; all improvements have to be done by the compiler! On top of that, the source code is ugly, grossly inefficient and poorly documented. In many ways, the SPEC really are the most representative benchmarks in the industry because of those three facts alone. Nevertheless, in order to improve generated code, one still has to understand why the processor is performing the…
Sandia National Laboratory Renews With Minimal Metrics
In the previous engagement, Minimal Metrics studied and successfully accounted for the performance differences between compilers of multi-dimensional stencil computations on Intel’s Jake Town and Ivy Town architectures. In that particular case, the Cray and Intel compilers were used and the work was primarily performed on Volta, the Cray CX30m. This machine is just one of the Advanced System Technology Test Beds present in the National Nuclear Security Agencies (NNSA) Advanced Simulation and Computing Project. These machines represent small sections of the design space on the path to an exascale computer, meaning a machine capable of a billion, billion (or 10 to the 18th power) floating point operations per second. For this new engagement, Minimal Metrics will be working closely with the test bed team to do performance studies of codes being developed to run on these (and tomorrow’s exascale) machines. The data gathered is intended not only to help guide…
Minimal Metrics at SC2014
Philip Mucci from Minimal Metrics will be attending the SC2014 show in New Orleans, LA from Nov 17 to the 20th. Get in touch with us if you’d like to schedule a meeting. If not, look for Phil in the booths of Texas Instruments, Scalable Informatics or the University of Tennessee.
Minimal Metrics partners with Reservoir Labs
Minimal Metrics has partnered with Reservoir Labs to work on the prototyping of a entirely new computer architecture and the development of algorithms to run on it. About Reservoir Labs: Reservoir solves the critical technology challenges of high performance computing. Our advanced computing and communications products, thought-leading research and novel technologies have made Reservoir a trusted and respected partner of corporate clients, government agencies, and leading researchers. We thrive on opportunities to learn and create as we develop and deliver groundbreaking science and security solutions. This particular project is indeed groundbreaking science, and as such, we can’t say more other that we’re thrilled to be part of this effort, and to be working with our friends at Reservoir Labs once again.
Minimal Metrics Optimizes Streaming Analytics for Ontario’s Electricity Provider
Minimal Metrics has signed a contract with Affinity Systems to assist in the optimization and tuning of a streaming data analytics application for the IESO, the Canadian Independent Electricity System Operator. As stated on their website: The Independent Electricity System Operator (IESO) balances the supply of and demand for electricity in Ontario and then directs its flow across the province’s transmission lines. The IESO works at the heart of Ontario’s power system, connecting all participants − generators that produce electricity, transmitters that send it across the province, retailers that buy and sell it, industries and businesses that use it in large quantities, and local distribution companies that deliver it to people’s homes. Minimal Metrics will assess and optimize the performance of a advanced streaming-data appliance responsible for the processing of millions of smart-meter readings taken constantly across the entire power grid. This appliance, built by Affinity Systems of Ontario, consists of a small…
Sandia National Laboratories Signs Minimal Metrics
Sandia National Laboratories has just signed Minimal Metrics to help in their performance analysis of their next-generation high-performance computing platforms. In particular, the Application Performance Modeling and Analysis team is interested in studying the effects of stall cycles on application performance. More specifically, parallel scientific simulation kernels running on Intel’s Sandy Bridge systems. Stall cycles, or periods of time where the processor is not producing any results, are notoriously difficult to account for. While the hardware architects have added some hardware instrumentation to help accomplish this, using that instrumentation requires extensive background and understand of the specific microprocessor’s architecture. Sandia, while possessing leading expertise in application performance, is looking to leverage Minimal Metrics’ unparalleled experience in the field in an attempt to further their research. Minimal Metrics will be working closely with Sandia’s application developers and systems teams to ensure that their code and systems are working as optimally as…
