Brief Introduction to the Graph 500 List

Data intensive supercomputer applications are increasingly important HPC workloads, but are ill suited for platforms designed for 3D physics simulations. Current benchmarks and performance metrics do not provide useful information on the suitability of supercomputing systems for data intensive applications. A new set of benchmarks is needed in order to guide the design of hardware architectures and software systems intended to support such applications and to help procurements. Graph algorithms are a core part of many analytics workloads. Backed by a steering committee of over 30 international HPC experts from academia, industry, and national laboratories, Graph 500 will establish a set of large-scale benchmarks for these applications. This BOF will unveil the first Graph 500 list, and discuss both today’s Graph 500 benchmark and the evolution of that benchmark going forward. The Graph 500 steering committee is in the process of developing comprehensive benchmarks to address three application kernels: concurrent search, optimization (single source shortest path), and edge-oriented (maximal independent set). Further, we are in the process of addressing five graph-related business areas: Cybersecurity, Medical Informatics, Data Enrichment, Social Networks, and Symbolic Networks. The BOF will offer a forum for community and provide a rallying point for data intensive supercomputing problems, and follows the introduction of the Graph 500 at ISC2010. This is the first serious approach to complement the Top 500 with data intensive applications. Additionally, we are working with the SPEC committee to include our benchmark in their CPU benchmark suite. We anticipate the list will rotate between ISC and SC in future years.

TOP500

10:00 pm in Lists by CSS

The main objective of the TOP500 list is to provide a ranked list of general purpose systems that are in common use for high end applications. In the TOP500 list computers ranked by their performance on the LINPACK Benchmark.

The Green500 provides rankings of the most energy-efficient supercomputers in the world. We raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.

HPC Challenge Benchmark Results

3:38 pm in Lists by CSS

The HPC Challenge benchmark consists of basically 7 tests:

1. HPL – the Linpack TPP benchmark which measures the floating point rate of execution for solving a linear system of equations.

2. DGEMM – measures the floating point rate of execution of double precision real matrix-matrix multiplication.

3. STREAM – a simple synthetic benchmark program that measures sustainable memory bandwidth (in GB/s) and the corresponding computation rate for simple vector kernel.

4. PTRANS (parallel matrix transpose) – exercises the communications where pairs of processors communicate with each other simultaneously. It is a useful test of the total communications capacity of the network.

5. RandomAccess – measures the rate of integer random updates of memory (GUPS).

6. FFT – measures the floating point rate of execution of double precision complex one-dimensional Discrete Fourier Transform (DFT).

7. Communication bandwidth and latency – a set of tests to measure latency and bandwidth of a number of simultaneous communication patterns; based on b_eff (effective bandwidth benchmark).
