Xoreax Software Finds Diamonds in the Cloud

By Rich Brueckner | Published May 25, 2012

Xoreax Software announced recently that diamond-producer Sarin Technologies has has adopted the company’s IncrediBuild-XGE acceleration software. Sarin is using IncrediBuild-XGE to accelerate the performance of Sarin Advisor, a specialized diamond analysis application that maximizes the value of raw diamonds. The software calculates millions of potential diamond cutting options and identifies optimal cutting patterns based on stone attributes including size, weight, and internal flaws.

Our adoption of IncrediBuild-XGE is really a win for our customers,” explained Uzi Levami, Chief Executive Officer of Sarin. “With IncrediBuild-XGE, we not only maximize diamond value for clients involved in gemstone production and extraction, but also enable them to save significant time and resources.”

Using traditional sequential processing, full optimization analyses for complex projects used to take as long as 40-60 hours. By applying IncrediBuild-XGE software acceleration technology, Sarin was able to slash processing time to 1 or 2 hours. In other cases, simpler 1 to 2 hour analysis processes now finish within 10-15 minutes. Workflows that once took several days have been reduced to a single night’s run.

Warewulf Cluster Manager is “Howlingly Great”

By Rich Brueckner | Published May 23, 2012

Over at HPC Admin, Dell’s Jeff Layton has posted an in-depth look into the open source Warewulf Cluster Manager.

In this article, I want to discuss the one I have been using for a long time: Warewulf. It pioneered many of the stateless methods that other tools use today and is considered the standard stateless open source toolkit for clustering. It is primarily a stateless cluster provisioning and management tool that can also be installed as a stateful tool (i.e., installed onto disks in the compute nodes). It is simple, automates the process, and is very scalable. In this four-part series on using Warewulf in production clusters, I’ll start by discussing how to install Warewulf on a master node and statelessly boot compute nodes.

Video: Programming Heterogeneous Many-cores Using Directives

By Rich Brueckner | Published May 23, 2012

In this Part 1 of this video, Francois Bodin from CAPS presents: Programming Heterogeneous Many-cores Using Directives.

Directive-based programming is a very promising technology to deal with Many-Core. In this context, HPC users can rely on emerging standards such as OpenACC and OpenHMPP. CAPS will introduce OpenACC and HMPP directive-based programming models with companion tools (e.g. for tracing, tuning, debugging): HMPP Wizard, CULA, ArrayFire, Vampir, Paraver, DDT, CodeletFinder, etc. The speakers will provide insights on how GPU / CPU can be exploited in a unified manner and how code tuning issues can be minimized. The discussion will also cover the use of libraries which is essential when addressing Many-Core Programming. Pathscale will present its product supporting OpenHMPP programming model.

Recorded at GTC 2012 in San Jose. Download the slides (PDF).

In Part 2 of this video (starting at the 30 minute mark) Christopher Bergstrom from Pathscale presents: Pathscale Enzo. ENZO is a complete GPGPU and multi-core solution, which tightly couples the best programming models with highly optimizing code generation for Nvidia Tesla. Download the slides (PDF).

Podcast: DDN WOS Software on OCP Storage Hardware to Enable Hyperscale Storage Clouds

By Rich Brueckner | Published May 22, 2012

In this podcast, Jeff Denworth from DDN provides details on the company’s recent announcement that their Web Object Scaler (WOS) will support Open Compute server and storage platforms in cooperation with the Open Compute Project.

Historically, there has not been an industry movement around standardizing and driving the adoption of mass-market hyperscale hardware technology,” said Jean-Luc Chatelain, Executive Vice President of Strategy and Technology, DDN. “With the new OCP storage hardware specification, DDN is able to focus its cloud storage efforts and investments on the software intelligence that drives today’s business and social connection. The Open Compute movement allows us to harness the power of crowd-sourced hardware design and a highly optimized supply chain to drive the best value for our customers.”

Slidecast: Allinea Software – Meeting the Quest to Run Applications Faster

By Rich Brueckner | Published May 21, 2012

In this slidecast, Patrick Wohlschlegel from Allinea Software describes the company’s advanced parallel debugging capabilities.

Our mission is to make it easier for software developers and scientists to make their software scale up to take full advantage of current and emerging parallel computer systems. We do this by developing innovative tools that ensure correctness and optimization of parallel codes, and we are recognized as a leader and innovator in our market. We created the world’s first petascale debugger - allowing users for the first time to debug at any scale. We also developed the first hybrid GPU debugger - enabling simultaneous debugging across multiple architectures in the same tool.”

As announced recently, the Allinea DDT software is being used by the NCSA Blue Waters team to fix their bugs at full scale and exploit the maximum computational power.

Hybrid Computing’s Radical Growth

By Staff | Published May 16, 2012

 

Our GTC 2012 coverage continues as Dan Olds examines the growth of the CUDA environment from 150,000 downloads in 2007 to 1.5 million today:

More importantly, there are 35 NVIDIA-fueled hybrid supercomputers on the Top500 list today. The NDUT Tianhe-1A system, with 14,300 CPUs and 7,100 NVIDIA GPUs, held down the top spot on the list in 2010. The upcoming Oak Ridge Titan system will sport more than 18,000 CPUs alongside 18,000 GPUs, and should become the fastest supercomputer in the world sometime this fall.”

New Whitepaper: Dynamic Parallelism in CUDA

By Rich Brueckner | Published May 16, 2012

The details on Dynamic Parallelism were hard to find after the new feature was introduced as part of the GTC 2012 keynote yesterday. Now Nvidia has followed up with a short whitepaper that describes how it works.

Dynamic Parallelism in CUDA is supported via an extension to the CUDA programming model that enables a CUDA kernel to create and synchronize new nested work. Basically, a child CUDA Kernel can be called from within a parent CUDA kernel and then optionally synchronize on the completion of that child CUDA Kernel. The parent CUDA kernel can consume the output produced from the child CUDA Kernel, all without CPU involvement.

Video: The Future is Parallel, and the Future of Parallel is Declarative

By Rich Brueckner | Published May 16, 2012

In this video, Simon Peyton Jones from Microsoft Research presents: The Future is Parallel, and the Future of Parallel is Declarative.

If you want to program a parallel computer, it obviously makes sense to start with a computational paradigm in which parallelism is the default (ie functional programming), rather than one in which computation is based on sequential flow of control (the imperative paradigm). And yet… functional programmers have been singing this tune since the 1980s, but do not yet rule the world. In this talk I’ll say why I think parallelism is too complex a beast to be slain at one blow, and how we are going to be driven, willy-nilly, towards a world in which side effects are much more tightly controlled than now. I’ll give a whirlwind tour of a whole range of ways of writing parallel program in a functional paradigm (implicit parallelism, transactional memory, data parallelism, DSLs for GPUs, distributed processes, etc, etc), illustrating with examples from the rapidly moving Haskell community, and identifying some of the challenges we need to tackle.

Recorded at the 2011 YOW! Australia Software Developer Conference.

China’s Big Supers Described as “Tractors on the Highway”

By Rich Brueckner | Published May 15, 2012

While China has more systems on the TOP500 than any other country except for the U.S., the China’s People’s Daily writes that the country’s vaunted supercomputing efforts are being stifled by a shortage of tuned applications, experienced developers, and poor development environments.

Xi Zili, director of the Shanhai Supercomputer Center, said that China can now be regarded as a major supercomputer country but is far away from a supercomputer power. Compared with the computing speed and performance, the application of the supercomputers obviously lags far behind. It is reasonable that someone describes the application of China’s supercomputers as “tractors on the highway.”
