GPU Technology on Center Stage at GTC '10
Post Date: September 27, 2010 @ 7:26 PM, Pacific Daylight Time
Blog: Behind the Cloud

At this year's GPU Technology Conference in San Jose, GPU computing in the scientific and technical research space took center stage, almost to the point where it became possible, at least for a moment, to forget the gaming roots and movement from the mainstream to the deeply technical.

Free Market Clouds: Why Cloud Computing Will Reinvigorate Capitalism
Post Date: September 22, 2010 @ 9:35 AM, Pacific Daylight Time
Blog: Behind the Cloud

I believe that the impact of cloud computing to the IT industry and to society at-large will be as significant as the Industrial Revolution was to market economies, otherwise known as capitalism. I’d like to explore the benefits of cloud computing, along with some potential threats.

The Fate of Oracle’s Grid Engine: To HPC or Not to HPC?
Post Date: September 16, 2010 @ 10:27 AM, Pacific Daylight Time
Blog: Behind the Cloud

HPC is where innovation happens in enterprises.Oracle can assist enterprises today in managing costs, employees, distribution channels, their sales force and all that good stuff. But creating innovative new products and solutions,which in the long term form the basis of growth isn't really connected to Oracle’s classical enterprise products.

Blog: Behind the Cloud

The cloud may be flattening the technology landscape, but it’s also offering advantages for organizations of every size. Enterprises certainly can’t relax knowing they have a technology advantage today. But they shouldn’t be worrying either provided their exploring all the cloud has to offer.

The Evolution of Oracle Grid Engine

Many have speculated that Oracle will drop the HPC related bits and pieces which came with the acquisition of Sun, including the Sun-developed Grid Engine. Some might doubt that Oracle management will ever be ever able to recognize the value of HPC technology for mainstream IT, but especially the value of resource managers like Grid Engine for any kind of distributed resource environment.

Clearing the HPC Cloud Cache
Post Date: September 08, 2010 @ 12:07 AM, Pacific Daylight Time
Blog: Behind the Cloud

The web provides users in all fields the capability to interact with HPC cloud users, developers and vendors. As the area grows to encompass an increasing number of interested parties, the resources to discuss the topic will grow. Today we clear the cache from the past week or two of browsing and share some sites on the radar.

Is a Single Vendor Solution the Right Approach to Cloud?
Post Date: September 07, 2010 @ 6:15 AM, Pacific Daylight Time
Blog: Behind the Cloud

HP is adopting cloud technologies from the solution perspective that puts the work back on technology as a whole. I’ve long thought that application design makes virtualization and other technologies easier to manage, and that is not even taking into account availability requirements such as disaster recovery.

Are RTOs Forgotten With Data Protection in the Cloud?
Post Date: August 31, 2010 @ 1:56 PM, Pacific Daylight Time
Blog: Behind the Cloud

Regardless of how the cost argument is defended, one area that emerges in discussions about cloud-based data protection is the recovery time objective or RTO. The root of this discovery is that traditional storage options, even the venerable tape media category, have fast transfer rates. The hard question is do we put a price on an RTO?

Virtualization is Not Cloud...But Does Make It Shine
Post Date: August 31, 2010 @ 1:29 PM, Pacific Daylight Time
Blog: Behind the Cloud

Virtualization does not a cloud make, but it does certainly aid with the advancement and wider adoption of cloud computing across the business and research spectrum. Initially emerging as a business decision, virtualization has now developed a life of its own both within and independent of the cloud model.

SSDs are worth it if they are dedicated to data that's read frequently, such as information in a database or popular multimedia content. However, what's most popular can change over time, and not all the data in a particular LUN (logical unit number) may qualify.

CometCloud: Using a Federated HPC-Cloud to Understand Fluid Flow in Microchannels

The ever-growing complexity of scientific and engineering problems continues to pose new computational challenges. Thus, we present a novel federation model that enables end-users with the ability to aggregate heterogeneous resource scale problems. The feasibility of this federation model has been proven, in the context of the UberCloud HPC Experiment, by gathering the most comprehensive information to date on the effects of pillars on microfluid channel flow.

CERN, Google, and the Future of Global Science Initiatives

Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).

NASA Builds 'Climate in a Box'

May 23, 2013 | The study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

Running Computational Fluid Dynamics in the Cloud

May 16, 2013 | When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
