This webinar introduces computing with accelerators and how they can augment traditional multi-core processing from laptop and deskside systems to supercomputers. The topics covered will include:
- Hardware overview, what makes an accelerator
- Graphics Processing Units
- Field Programmable Gate Arrays (FPGA)
- Academic GPU computing started at UIUC, NCSA stood up the first GPU clusters:
- Software overview, how accelerators are utilized
- Simple code walkthroughs to demonstrate programming concepts (OpenACC, CUDA)
- Example applications (fields of science, production libraries, codes)
Prerequisites: No prior HPC experience is needed.
As a system engineer with NCSA, Galen enjoys helping people get the most out of HPC systems such as: Blue Waters and XSEDE systems with accelerators. He’s part of the Blue Waters applications support team as well as the XSEDE software development and integration testing group. He has a good working knowledge of most things unix/linux/hpc/networking and has a knack for debugging code. He believes k&r-c is the one true language but reluctantly admits the superior numerical performance of fortran codes.
