In today’s information-saturated world, the huge growth of geographically distributed data necessitates a system that facilitates fast parsing for the retrieval of meaningful results. A searchable index for distributed data would go a long way toward speeding the process. This article demonstrates using Lucene and Java for basic data indexing and searching, using [...]

For a long time now, we’ve known that sustained performance on clusters is a complicated thing to measure, especially when talking about parallel jobs. In columns like this one, and others too numerous to count, it has been stressed that sustained performance for real applications is [...]

In the last article, I have described how OpenMP source code is processed by an OpenMP compiler. OpenMP compilers resemble the typical compiler pipeline of traditional compilers and augment it with OpenMP-specific stages and passes that transform OpenMP code to multi-threaded execution (see also the picture below as a reminder). In this article, [...]

We all know that OpenMP is a well-known, widely accepted programming model for parallel programming on shared-memory platforms. It is based on so-called OpenMP directives that programmers add to their code to inform the compiler about which fragments of the program can be executed in parallel. Most of OpenMP is designed to [...]

David Kirk, an Nvidia Corp. fellow and the former chief scientist of the graphics company, admitted that heterogeneous computing architecture is the most efficient since it allows to process all types of data in the best way. But Mr. Kirk is not sure that Intel Corp., which is developing its multi-core code-named [...]

The number of processors, both x86 and GPU, available for rendering has been increasing exponentially. Rendering is one of the applications that can soak up all the cycles that are available to it, which is an example of Peddie’s first law – In computer graphics, too much is not enough.
Peddie’s research group looked [...]

Rather than using threads, functional programming presents the superior approach for developers who must program for newfangled multicore processors, XML co-inventor Tim Bray stressed at a technical conference on Friday.
Programming for multicore chips requires that developers deal with concurrency, which brings its own issues, Bray said in a presentation at the [...]

If there’s one technology that can greatly improve computing environments of any size, it’s virtualization. By using a single physical server to run many virtual servers, you can decrease operational costs and get far more bang for your buck. Whether your company is a 2-server or 2000-server shop, you can benefit [...]

The central concept behind benchmarks was historically pretty simple. What’s the horsepower of some vendor’s “Big Iron”? After all, most systems–the important ones, anyway–were the big boxes sitting in a data center someplace doing important stuff like booking orders or counting money.
They cost a lot. They were based on proprietary architectures that [...]
