Udeepta Bordoloi walks though several different ways to optimize an image convolution algorithm. He explains the thinking behind tweaking the workgroup size, type of memory used, and data types that result in incredible speedups. If you use convolution you will definitely not want to miss this step-by-step optimization video.

Just released: LibM Version 2.1
This latest release features 46 new vector functions spread among 4 function groups. The vector functions include array variants (those that operate on buffers) and vector data-type variants (those that operate on elements of an SSE data type). It also includes 2 new scalar functions, remquo and remquof, and some example programs to illustrate usage of the AMD LibM functions.

Better Uptime for Long Running Java Applications
AMD Java Labs submitted a new change to OpenJDK to overcome a long standing problem in the HotSpot JVM, that is that there was no mechanism in the JVM to recover if the code cache of compiled Java methods became full. Our change introduces a way for the code cache to be selectively cleaned based on application behavior which should allow the application's hot methods to remain compiled and continue to run at full speed.

AMD and I/O Virtualization on "Magny-Cours" Processors
In virtualization, device emulation is the most time-consuming component. The overhead comes from intercepting DMA accesses and interrupts for guest OS. To prevent malicious DMA accesses from un-authorized devices, the hypervisor has to intercept all DMA requests and then copy the data to (or from) the guest memory area. Learn how AMD-Vi™, a new hardware feature added to the AMD SR56×0 chipset, can be used to control DMA accesses and interrupts for devices installed on the system.
