OptiX 2.1 continues to redefine interactive possibilities for ray tracing developers with important new advances enabling farther reach and faster performance with support for: * 64-bit device code compilation, allowing access to the full 6GB of Quadro 6000 and Tesla 2070 solutions. * CUDA 3.1 and CUDA 3.2 support. * New rtuTraversal API for easily computing intersections of batches of rays with geometry without the need to setup an OptiX pipeline. Note that this API is currently in Beta. * Performance improvements up to 80% for many heavy workloads over previous OptiX versions. * Universal binary (i386 + x86_64) support for Mac OptiX libraries.
The cuda-gdb debugger is an extended version of the open source gdb debugger, providing seamless native hardware debugging across CPUs and GPUs. First introduced in 2008, cuda-gdb supports all 250,000,000+ CUDA architecture GPUs with compute capability 1.1 or later. A preview release of cuda-gdb for MacOS is now available
