"Transformers jokes aside, NVIDIA's newest technology offering hopes to radically change the way notebook computers are built and how customers use them. The promise of both extended battery life and high performance mobile computing has seemed like a pipe dream, and even the most recent updates to 'switchable graphics' left much to be desired in terms of the user experience. Having both an integrated and discrete graphics chip in your notebook does little good if you never switch between the two. Optimus allows the system to seamlessly and instantly change between IGP and discrete NVIDIA GPUs based on the task being run, including games, GPU encoding or Flash video playback. Using new software and hardware technology, notebooks using Optimus can power on and pass control to the GPU in a matter of 300ms and power both the GPU and PCIe lanes completely off when not in use. This can be done without being forced to reboot or even close out your applications, making it a hands-free solution for the customer."

"An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."

Kaspersky Labs announced that they’re leveraging GPU computing (CUDA) with NVIDIA Tesla GPUs to dramatically improve the performance of their security software solutions by *360 times* when compared to a Core2 Duo. Now thats a big speedup! There are other previous works like ClamAV on GPU and SNORT on GPU.
Kaspersky Lab uses the NVIDIA Tesla S1070 1U GPU system to accelerate the screening of malicious programs using a unique file similarity detection technology. When the Kaspersky anti-virus software on a computer suspects that a file may be malicious, even though it may not match any known virus signatures, the software uploads this file to the Kaspersky Lab data center. The server software then compares the suspected file against more than 50 million known good files and programs. Using complex anti-virus and SPAM detection algorithms, Kaspersky’s server software identifies the risk level of the suspected file and informs the client computer on what kind of preventive action to take..
