Successfully Managing Workload Convergence in Your Data Center

Modern enterprises are being challenged to implement new technologies and produce results faster without increasing their IT budgets. This is the first a series of features exploring new resource management solutions for workload convergence, such as Bright Cluster Manager by Bright Computing.

New HPC for Energy White Paper looks at Exascale Architectures for Greener Combustion Systems

The use of new Exascale architectures and the corresponding advances in codes to fully exploit new chip capabilities will help address challenges for combustion technologies, wind power generation and hydrocarbon exploration, allowing a transition to greener and more advanced energy systems based on alternative fuels combined with renewable energy technologies. “This project has revealed the synergies between European and Brazilian researchers, and has strengthened the bilateral relationships. From the point of view of the technical results, the project has been a success, having achieved all the planned objectives.”

ClusterVision White Paper Looks at HPC Performance Impact of Spectre and Meltdown

While various kernel patches are already out for the Spectre and Meltdown, the performance impact of these patches on HPC performance has been a big question. Now ClusterVision has published a timely white paper on this important topic. “These vulnerabilities have only been discovered recently, so information is still developing. Therefore, this document should not be interpreted as a complete overview of the situation but as an informative view of the potential impact on HPC.”

New Whitepaper on Meltdown and Spectre fixes for HPC

Can you afford to lose a third of your compute real estate? If not, you need to pre-empt the impact of Meltdown and Spectre. “Meltdown and Spectre are quickly becoming household names and not just in the HPC space. The severe design flaws in Intel microprocessors that could allow sensitive data to be stolen and the fixes are likely to be bad news for any I/O intensive applications such as those often used in HPC. Ellexus Ltd, the I/O profiling company, has released a white paper: How the Meltdown and Spectre bugs work and what you can do to prevent a performance plummet.”

First Global Survey of Energy and Power Aware Job Scheduling and Resource Management

In this special guest feature, Siddhartha Jana summarizes the key findings of the first-of-its-kind survey on Energy and Power Aware Job Scheduling and Resource Management. “The goal of this year-long survey was to investigate the active investments by HPC centers in enabling energy and power management within their software stack, especially the job schedulers and resource managers.”

New Paper looks at Unsupervised Machine Learning on Rigetti 19Q Quantum Computer

Over at Rigetti Computing, Will Zeng writes that the company has published a new white paper on unsupervised machine learning using 19Q, their new 19-qubit general purpose superconducting quantum processor. To accomplish this, they used a quantum/classical hybrid algorithm for clustering developed at Rigetti.

From SC17: Energy Efficiency in the Software Stack — Cross Community Efforts

In this special guest feature, Siddhartha Jana provides an update on cross-community efforts to improve energy efficiency in the software stack. The article covers events at SC17 that focused on energy efficiency and highlights ongoing collaborations across the community to develop advanced software technologies for system energy and power management.

All about Baselining: RedLine Explains HPC Performance Methodology

In HPC we talk a lot about performance, and vendors are constantly striving to increase the performance of their components, but who out there is making sure that customers get the performance that they’re paying for? Well, according to their recently published ebook, a company called RedLine Performance Solutions has adopted that role with gusto.

Banshee Makes DRAM Cache up to 50 percent more efficient

Researchers from MIT, Intel, and ETH Zurich have developed a new cache-management scheme that improves the data rate of in-package DRAM caches by 33 to 50 percent. “The bandwidth in this in-package DRAM can be five times higher than off-package DRAM,” says Xiangyao Yu, a postdoc in MIT’s Computer Science and Artificial Intelligence Laboratory and first author on the new paper. “But it turns out that previous schemes spend too much traffic accessing metadata or moving data between in- and off-package DRAM, not really accessing data, and they waste a lot of bandwidth. The performance is not the best you can get from this new technology.”

GPUs Power Near-global Climate Simulation at 1 km Resolution

A new peer-reviewed paper is reportedly causing a stir in the climatology community. “The best hope for reducing long-standing global climate model biases, is through increasing the resolution to the kilometer scale. Here we present results from an ultra-high resolution non-hydrostatic climate model for a near-global setup running on the full Piz Daint supercomputer on 4888 GPUs.”
