Leveraging asynchronous queues for concurrent execution

• Tags:

GPUOpen has posted a new entry "Leveraging asynchronous queues for concurrent execution." Understanding concurrency (and what breaks it) is extremely important when optimizing for modern GPUs. Modern APIs like Vulkan provide the ability to schedule tasks asynchronously, which can enable higher GPU utilization with relatively little effort.

Amazon EC2 Elastic GPUs support OpenGL

• Tags:

Amazon EC2 users will soon have the ability to add OpenGL acceleration to existing EC2 instance types. Amazon-optimized OpenGL library will automatically detect and make use of Elastic GPUs. Amazon will start out with Windows support for OpenGL, and plan to add support for the Amazon Linux AMI and other versions of OpenGL after that. The GPU added to the instance can have 1, 2, 4, or 8 gigabytes of video memory. It’s becoming much easier to use OpenGL from GPUs in the cloud.
