Webinars Showing How to GPU Accelerate Python With Numba

November 24, 2015 by Rob Farber Leave a Comment

Register to attend a webinar about accelerating  Python programs using the integrated GPU on AMD Accelerated Processing Units (APUs) using Numba, an open source just-in-time compiler, to generate faster code, all with pure Python. This webinar will be presented by Stanley Seibert from Continuum Analytics, the creators of the Numba project. This webinar is tailored to an … [Read more...]

AMD to Support CUDA Compatibility in 2016

November 23, 2015 by Rob Farber Leave a Comment

TechEnablment spoke with the AMD engineers at SC15 about the HIP (Heterogeneous-compute Interface for Portability) tool for porting CUDA-based applications to a common C++ programming model that can run on AMD FirePro™ graphics processing units (GPUs). AMD demonstrated the potential for HIP by running the CUDA-generated Rodinia benchmark suite on AMD GPUs. The tagline is "It's … [Read more...]

Port Some CUDA Codes To Intel Xeon Phi Simply and Efficiently

May 15, 2015 by Rob Farber Leave a Comment

This tutorial shows that it relatively easy to port many CUDA C/C++ source codes to OpenMP. In the past, such efforts were not generally considered worthwhile because of the large performance difference between multicore processors (that use OpenMP) and GPUs. The introduction of teraflop/s Intel Xeon Phi coprocessors eliminated that performance difference, which makes it much … [Read more...]

PGI Compiled OpenACC ILP Loop Beats CUDA-7 by 200 GF/s on Deep-learning PCA Example

March 23, 2015 by Rob Farber Leave a Comment

The PGI OpenACC compiler beat the performance of a CUDA 7.0 NVIDIA nvcc compiled deep-learning based PCA (Principal Components Analysis) example by 200 GF/s on a K40c using an ILP (Instruction Level Parallelism) loop structure taught in the TechEnablement classes and forthcoming Farber OpenACC book. PCA is an important data analysis tool utilized by data scientists. Sign up for … [Read more...]

CUDA 7 For Registered Developers – LAPACK Dense Solvers 3-6x faster than MKL

January 13, 2015 by Rob Farber Leave a Comment

The CUDA Toolkit 7.0 Release Candidate (RC) is now available to members of NVIDIA’s free registered developer program. Especially interesting is the claim of 3-6x faster LAPACK dense solvers over MKL (The Intel Math Kernel Library). C++11 support makes it easier for C++ developers to accelerate their applications Write less code with ‘auto’ and ‘lambda’, especially when … [Read more...]

ORNL Introductory Tutorials On Concurrent Kernels

January 1, 2015 by Rob Farber Leave a Comment

The OLCF at Oakridge National Laboratory (ORNL) is working to educate  users about how to best use their computing resources. As part of that process, the OLCF has published two very introductory tutorials to teach how to utilize concurrent kernels on their systems. Part 1 (concurrent kernels) and Part 2 (batched library calls) teach how to launch concurrent kernels using CUDA … [Read more...]

IPMACC – An Open Source OpenACC to CUDA/OpenCL Translator

December 23, 2014 by Rob Farber Leave a Comment

IPMACC is  a research-grade open-source framework for translating OpenACC source code to CUDA or OpenCL. Binary executables can then be created with OpenCL or CUDA compilers. The authors (Ahmad Lashgar - University of Victoria, Alireza Majidi - Texas A&M University, Amirali Baniasadi - University of Victoria)  verified correctness and performance using benchmarks from … [Read more...]
