Big thanks for Michael Gale for the .NET binding
Brussels, May 4, 2010 – At the Research@Intel, Europe event in Brussels Intel Labs Europe showed a new technology that could dramatically improve performance of microprocessors when running older software. The technology called “Anaphase” has been developed at Intel Labs Barcelona.
Current processor designs have shifted towards multi-core. Nevertheless single thread performance remains very important as many applications have limited thread-level parallelism. As a result, users executing one of these applications experience little benefit from new multi-core processors.
Researchers from Intel Labs Barcelona now presented “Anaphase” which is a novel hardware/software hybrid approach to leverage multiple cores in order to improve single-thread performance on multi-core processors. This research focuses on different speculative techniques to automatically partition single thread applications to be processed on multiple cores.
On the hardware side, a new unit called “Inter-Core Memory Coherency Module” (ICMC) could be integrated into the die of future processors. The ICMC updates the memory state in program order, detects memory violations and implements check-pointing and recovery mechanisms, so that it can execute the resulting partitioned applications on multiple cores.
First simulated benchmarks running 12 SpecFP and 12 SpecInt benchmarks of the SPEC2006 suite show dramatic average performance improvements of 31% to 41% (depending on core size) over non-Anaphase optimized systems. At the present Anaphase is a research project and the Intel Labs Barcelona researchers are looking into ways how to potentially integrate this technology into future processor designs.
GPCBencMarkOCL is a General Purpose Computing benchmark that evaluates the performance of OpenCL enabled devices with a collection of several algorithms and applications. The first generation of OpenCL and DirectCompute benchmarks have very limited functions and test items, which could not give a all-around performance evaluation.
What is the state of fluid simulation in games today?
--Most games do not perform fluid simulation. Usually they use particle systems where the particles do not interact with each other.
SmallLuxGPU is a LuxRays (http://luxrender.net/wiki/index.php?title=LuxRays) demo and a LuxRender v0.8 "proof of concept" (http://luxrender.net/wiki/index.php?title=Luxrender_and_OpenCL).
Real-time sequences were recorded on a i7 860 + HD5870 + HD5850 at the resolution of 800x450. Off-line sequences were rendered with a i7 860 + HD5870 + HD5850 at the resolution of 1280x720.
SmallLuxGPU and LuxRays are released under GPL license and the sources are available here http://src.luxrender.net/luxrays/. Precompiled binaries are available on LuxRender forums (check the section dedicated to GPU acceleration).
NVIDIA Application Configuration Engine (ACE)
This driver includes the NVIDIA Application Configuration Engine (ACE), which
automatically detects the workstation application and configures the appropriate profile
settings in the NVIDIA Control Panel.
See the NVIDIA Quadro Professional Drivers: NVIDIA Control Panel Quick Start Guide for
more information about this feature.
SLI Multi-OS – GPU Assignment in System Virtualization
On systems with two supported graphics cards installed, this driver supports a system
virtualization tool’s ability to directly assign a GPU to a guest virtual machine (VM). This
direct assignment allows the host and guest VM to each run on their own operating
system and with their own GPU and driver.
Supported Virtualization Software: Parallels Workstation Extreme
Supported Graphics Cards
Up to two different models can be used in a system, from among the following:
• Quadro FX 5800
• Quadro FX 4800
• Quadro FX 3800
Video BIOS Requirement
• The graphics card assigned to the guest VM needs video BIOS version
62.00.39.00.00 or later.
For a list of SLI Multi‐OS certified workstations, virtualization software, and OS
combinations, please see http://www.nvidia.com/object/sli_multi_os.html (not yet online or wrong link).
