The era of exascale computing, which can execute 1018 operations in a second, is just around the corner. With the theme of 'Moving Forward with Supercomputing!', the Korea Institute of Science and Technology Information (KISTI) is holding the 18th Korea Supercomputing Conference (KSC). It is the largest academic supercomputing conference and exhibition in Korea. It aims to expand the awareness of supercomputing, computational science and engineering, foster industries to invigorate and catalyze the 4th industrial revolution, and to promote academics among researchers.

As a part of the tutorial of the Korea Supercomputing Conference, the Korea Institute of Science and Technology Information, in association with NVIDIA and, is organizing a half-day training on how to accelerate your HPC code with OpenACC on NVIDIA GPUs.

This KSC GPU Bootcamp is open to the 2021 KOREA SUPERCOMPUTING CONFERENCE attendees only, and will be hosted in Korean. Please note that this event has limited capacity and is first come, first served.

Event Format

This half-day online Bootcamp will be taught in the local language and hosted in the Korean Standard Time (KST) zone. All communication will be done through Zoom, Slack, and email..
