Speaking at the Hot Chips Conference, HSA Foundation president Phil Rogers has provided more details on plans to bring GPU acceleration to Java in time for Java 9 in 2015.
Version 1.1 of Google's Go is in beta, and brings significant reported performance increases, new toolset & language features. It maintains backwards compatibility with Go 1.0 and in most cases a recompile is the only thing needed to take advantage of this release.
There are two major browser developments recently announced, both targeting parallel architectures: Google and Opera with Blink, a WebKit fork, while Samsung joins Mozilla to push Servo forward.
The Dutch company Vector Fabrics recently introduced its tool called Pareon. According to the company’s press release, the tool allows to optimize applications for multicore systems.
Hoping to make programming data-parallel hardware easier, Microsoft has published its open specification for C++ AMP. By building its implementation directly into Visual Studio 11 Microsoft seeks to improve access to the GPU for developers.
It is hard to leverage the parallelism provided by recent processor architectures. As these CPUs are now available even in the low cost price sector, the main challenge of software engineers is to utilize the processors in their applications or apps. The International Conference on Multicore Software Engineering, Performance, and Tools (MSEPT'12) will focus on possible answers.
Dataflow Blocks are the backbone of the .NET 4.5’s new high performance parallel processing library. And while they offer a lot of functionality out of the box, there will be times when a custom block is necessary. Zlatko Michailov has put together a document outlining the process and many of the traps you may encounter.
Microsoft has been working on ways to improve the performance of parallel applications in .NET 4.5, specifically those using the Task Parallel Library. One of most impressive improvements is reducing the overhead for waiting on 100,000 tasks from 12,000,000 bytes to a mere 64 bytes.
Microsoft has released the Parallel Visualization Pack for Visual Studio 11 Developer Preview. Built to extend the functionality of the new Parallel Watch Window, the pack includes four visual tools to aid in debugging multithreaded applications.
Twitter has open-sourced Storm, its distributed, fault-tolerant, real-time computation system, at GitHub under the Eclipse Public License 1.0. Storm is the real-time processing system developed by BackType, which is now under the Twitter umbrella.
Microsoft wants to give C++ developers tools for writing parallel applications running on zillions of GPUs/cores locally or in the cloud.
With the increased emphasis on multi-core systems an understanding of parallel and concurrent programming is more important than ever. Fortunately .NET 4 has made a lot of advances in the types of synchronization primitives available to developers. One such primitive is the Barrier, which Emad Omara uses to implement a parallel merge sort.
