Compilers and More: A GPU and Accelerator Programming Model

December 9, 2008

If you are familiar with current approaches to programming accelerators, you are either discomforted by the complexities, or excited at the levels of control you can get. Can we come up with a different model of GPU and accelerator programming -- a model that allows HPC programmers to focus on domain science instead of on computer science? Read more…

HPC Clouds — Alto Cirrus or Cumulonimbus

November 21, 2008

The "cloud" model of exporting user workload and services to remote, distributed and virtual environments is emerging as a powerful computing paradigm. Yet, one domain that challenges this model in its characteristics and needs is high performance computing. Read more…

Incoming: 10 Gigabit Ethernet for HPC

November 20, 2008

InfiniBand has been a comfort zone for those tightly-coupled HPC applications that can't live without their addiction to low latency and high speed. If your application is a science experiment with good funding and no firm schedule, that's OK. If your application involves business, deadlines, and ROI, it's time to break out of that comfort zone and acquaint yourself with 10 Gigabit Ethernet. Read more…

The Search for Stable Storage

November 19, 2008

A team led by Thomas Schulthess of Oak Ridge National Laboratory has broken the petaflop barrier with a supercomputing application likely to accelerate the revolution in magnetic storage. Using ORNL's upgraded Cray XT Jaguar supercomputer, the team was able to achieve a sustained performance of 1.05 petaflops for an application that simulates the behavior of electron systems.

Why IT Must Have an Influential Role in Strategic Decisions About Sustainability

In this era, expansion in digital infrastructure capacity is inevitable. Parallel to this, climate change consciousness is also rising, making sustainability a mandatory part of the organization’s functioning. As computing workloads such as AI and HPC continue to surge, so does the energy consumption, posing environmental woes. IT departments within organizations have a crucial role in combating this challenge. They can significantly drive sustainable practices by influencing newer technologies and process adoption that aid in mitigating the effects of climate change.

While buying more sustainable IT solutions is an option, partnering with IT solutions providers, such and Lenovo and Intel, who are committed to sustainability and aiding customers in executing sustainability strategies is likely to be more impactful.

Learn how Lenovo and Intel, through their partnership, are strongly positioned to address this need with their innovations driving energy efficiency and environmental stewardship.

How Direct Liquid Cooling Improves Data Center Energy Efficiency

Data centers are experiencing increasing power consumption, space constraints and cooling demands due to the unprecedented computing power required by today’s chips and servers. HVAC cooling systems consume approximately 40% of a data center’s electricity. These systems traditionally use air conditioning, air handling and fans to cool the data center facility and IT equipment, ultimately resulting in high energy consumption and high carbon emissions. Data centers are moving to direct liquid cooled (DLC) systems to improve cooling efficiency thus lowering their PUE, operating expenses (OPEX) and carbon footprint.

This paper describes how CoolIT Systems (CoolIT) meets the need for improved energy efficiency in data centers and includes case studies that show how CoolIT’s DLC solutions improve energy efficiency, increase rack density, lower OPEX, and enable sustainability programs. CoolIT is the global market and innovation leader in scalable DLC solutions for the world’s most demanding computing environments. CoolIT’s end-to-end solutions meet the rising demand in cooling and the rising demand for energy efficiency.
