GPUs are specially designed to crunch through massive amounts of data at high speed. They have a large amount of compute resources, called streaming multiprocessors (SMs), and an array of facilities to keep them fed with data: high bandwidth to memory, sizable data caches, and the capability to switch to other teams of workers (warps) without any overhead if an active team has run out of data.
]]>As ray tracing becomes the predominant rendering technique in modern game engines, a single GPU RayGen shader can now perform most of the light simulation of a frame. To manage this level of complexity, it becomes necessary to observe a decomposition of shader performance at the HLSL or GLSL source-code level. As a result, shader profilers are now a must-have tool for optimizing ray tracing.

]]>We��ve all been there. Your CUDA Fortran code is humming along and suddenly you get a runtime error: , , usually accompanied by in all caps. In many cases, the error message gives you enough information to find where the problem is in your source code: you have a runtime error and you only perform a few host-to-device transfers, or your code ran fine before you added that block of code earlier��
]]>NVIDIA Nsight Eclipse Edition is a full-featured, integrated development environment that lets you easily develop CUDA applications for either your local (x86) system or a remote (x86 or Arm) target. In this post, I will walk you through the process of remote-developing CUDA applications for the NVIDIA Jetson TX2, an Arm-based development kit. Note that this how-to also applies to Jetson TX1 and��

The first part of this series provided an overview of the field of deep learning, covering fundamental and core concepts. The second part of the series provided an overview of training neural networks efficiently and gave a background on the��
]]>We often say that to reach high performance on GPUs you should expose as much parallelism in your code as possible, and we don��t mean just parallelism within one GPU, but also across multiple GPUs and CPUs. It��s common for high-performance software to parallelize across multiple GPUs by assigning one or more CPU threads to each GPU. In this post I��ll cover a common but subtle bug and a simple rule��
]]>NVIDIA Nsight Eclipse Edition (NSEE) is a full-featured unified CPU+GPU integrated development environment(IDE) that lets you easily develop CUDA applications for either your local (x86_64) system or a remote (x86_64 or ARM) target system. In my last post on remote development of CUDA applications, I covered NSEE��s cross compilation mode. In this post I will focus on the using NSEE��s synchronized��
