HPC in Asia 2017 - Status report from Taiwan


12 Jul 2017 Frankfurt - At the HPC in Asia workshop, Weicheng Huang, NCHC, gave an update on HPC in Taiwan. NCHC, the National Center for High-Performance Computing, is a national facility funded by the Ministry of Science and Technology, MOST. It provides computing, storage and networking services and does research in application areas like Engineering, Science, Biology and technologies like Grid, Cloud, Big Data. In total the computing capacity of the centre is 400 Tflop/s. The largest machine, the ALPS, has some 10 Tflop/s performance. In general there is a high utilisation of the machine. The demand, however, is 4 times higher than the capacity.

The machine is mainly used by scientific applications (69%); engineering and technology (15%); and Agriculture, Biology, and Medical Sciences (14%).

So there really is a need for a new, faster system. This new supercomputer will be installed in Q4 2017, with production runs starting in Q2 2018. The new system will be delivered by Fujitsu.

The peak performance will be 1,05 Petaflop/s which comes from 630 nodes with a total of 25.200 Xeon cores running at 2,4 GHz. Another 0,684 Petaflops will be delivered by 64 GPU nodes with 256 P100 GPUs. The total memory will be 157 Tbyte and the storage capacity 3, 4 Petabytes. The system connection is a fat-tree Omnipath.

The PUE will be 1,28 as a result of liquid cooling and in-row cooling. The power consumption will be 607,64 Kwatt.

The file systems - 3 of them - will run DDN Lustre.

The storage service currently has 9,7 Petabytes in 4 different centres across the country. It is 88% utilized. The network backbone in Taiwan now runs at 100 Gbps. Internationally, Taiwan is connected by two 10 Gbps lines to the US.

Currently, there are two main developments in Taiwan. One is the Data Market/National Data service which looks at 180 million data records to be processed. There is a 256 node Hadoop cluster for that in a highly secured environment.

For HPC/AI, there are plans for a 4-year project. There is, however, still some struggling going on at the political level. The budget could maybe be 166 million Taiwanese dollars. This would not be for hardware only, but also for 3 AI research centres.
