Organizing Committee

Aims and Scope

The Conference on Advanced Topics and Auto Tuning in High-Performance Scientific Computing focuses on the scientific impacts due to the latest computer architectures and the approaches to achieve high-performance computing on these leading-edge computers. Advances in many-core architectures and high-end computers have unveiled their significances in the scientific discoveries and engineering achievements. The complexity of these newly developed computers, however, also leads to contemporary challenges to achieve the best efficiency of the highly promising computational capabilities. The conference encourages interdisciplinary communications between researchers from applied mathematics, statistics, computer science, physical sciences, engineering and industry to prompt innovations and breakthroughs in this exciting field. The main themes include, but not limited to, simulations, numerical methods, applications, hardware, and particularly software and algorithm auto-tuning via statistical methods.

Transportation

From Taiwan Taoyuan International Airport (Airport code: TPE) to NTU

  • By Bus:

    • Several long-distance bus companies provide frequent services between Taiwan Taoyuan International Airport and downtown Taipei. The trip is about 60-90 minutes. Ticket counters are located in the Arrival Passenger Reception Areas of both Terminals. Luggage is self served. Adult single fares vary from NT$ 125 to NT$150 depending on the location of the terminal stop in Taipei. English flyers are distributed on the ticket counter. Most clerks are able to speak English and Japanese.

    • Recommended Bus Routes to NTU: Take the “Evergreen Motor Transport” or “Free Go Motor Transport” to Taipei metro Zhongxiao Fuxing Satation.
