AMD GCN is new design providing faster performance, higher efficiency, new compute and graphics features with world first GPU on 7-nm FinFET technology which delivers superior levels of architecture scalability from small laptop APU to powerful data center discrete GPU computing nodes. Unlimited Memory Resources & Samplers, all valid UAV formats, public assembly language with the ability to support C/C++ dialects. Architectural support for traps, exceptions & debugging combined with the ability to share virtual x86-64 address space with CPU cores in the same node and big system.
ROCm – Radeon Open Compute Initiative with Completely Open Source Software Stack and Collaboration with Academic and Industrial Community
Monday, March 11 at 10:00 am
Building 2, Level 5, Room 5220
ROCm software platform supports GPU acceleration using open-source Heterogeneous Computing Compiler (HCC) aka Heterogeneous Interface for Portability compiler (HIP), which allows developers to process code more easily with the C++ dialect registered as Clang input in LLVM stack. It provides full machine control for heterogeneous compute on CPU+GPU platform. ROCm provides a rich system run time supporting multiple APIs and programming languages. The ROCm platform also includes a comprehensive ecosystem of development tools and libraries to help port the code written for CUDA to C++ HIP. MIOpen is free and highly optimized open-source library for GPU accelerators enabling popular high-performance machine intelligence frameworks like Keras, Caffe/Caffe2, PyTorch, TensorFlow, MxNet and others.
GPU in High-Performance Computing and Machine Learning: Special Features in Architecture, Firmware and Software Libraries
Monday, March 11 at 12:00 pm
Auditorium betweeen Building 4 & 5, Level 0
Graphics accelerators for real-time visualization first appeared in mid-1970s as fixed function (FF) matrix multipliers and rasterization blocks to be used in flight simulators. Originally based on LSI logic components later in 1990s they have been implemented as single- or multi-chip ASIC-based accelerator with FF set supporting graphics API functionality (OpenGL and MS D3D). Early 2000s first limited programmable GPUs appeared and were followed by new generation of fully programmable and IEEE-754 compliant GPU which could be used for general purpose computing. Adding 64-bit double float support made new GPUs applicable in HPC applications. HPC applications caused significant modifications of GPU architecture originally targeted for vertex and pixel stream real-time processing. HPC capable GPU got the I/O and memory hierarchy architecture adjusted for multiprocessing cluster with complex interlink topology. Extending GPU deployment to machine learning domain cause to add low- and mixed-precision operations support as well as tensor processing acceleration units combined in the plurality of SIMD compute unit. Special highly optimized libraries and firmware were developed to support BLAS and other HPC utilities along with machine learning libraries like cuDNN and MIOpen.
