NVIDIA 378.66 drivers for Windows offer OpenCL 2.0 evaluation support

• Tags: windows drivers OpenCL

NVIDIA graphics driver for Windows version 378.66 is now offering some OpenCL 2.0 support. From the release notes: "New features in OpenCL 2.0 are available in the driver for evaluation purposes only." Some known issues include: The current implementation is limited to 64-bit platforms only; OpenCL 2.0 allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU; For executing kernels (whether from the host or the device), OpenCL 2.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by the local_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.

Intel FPGAs Break Record for Deep Learning Facial Recognition using OpenCL SDK

• Tags: SDK OpenCL

Today Intel announced record results on a new benchmark in deep learning and convolutional neural networks (CNN). The test took place in Nanjing City, China, where ZTE’s engineers used Intel’s midrange Arria 10 FPGA for a cloud inferencing application using a CNN algorithm. The benchmark was achieved on a server holding 4S Intel Xeon E5-2670v3 processors running at 2.30GHz, 128GB DDR4; Intel PSG Arria 10 FPGA Development Kit with one 10AGX115 FPGA, 4GB DDR4 SODIMM, Intel Quartus Prime and OpenCL SDK v16.1. Besides the impressive increase in performance, the team at the ZTE Wireless Institute sped design time with the use of the OpenCL programming language.

NVIDIA GTX 680 To GTX 1080 Blender OpenCL Benchmarks

• Tags: GPU benchmarks OpenCL phoronix

Phoronix has published benchmarks of 13 Kepler/Maxwell/Pascal NVIDIA GeForce graphics cards when testing Blender 2.78's OpenCL renderer. Unfortunately, no AMD OpenCL benchmarks for Blender yet -- the current open-source stack doesn't work until ROCm OpenCL support comes into play and the AMDGPU-PRO stack wasn't working for Blender OpenCL but was falling back to CPU rendering.
