Executive Director of the Institute of High
Performance Computing (IHPC), A*STAR
Dr Lim Keng Hui is the Executive Director of the Institute of High Performance Computing (IHPC) in A*STAR. He leads the research institute to advance scientific knowledge, and deliver impact to the industry and society through research in computational modelling and simulation, visualisation and artificial intelligence.
Prior to his current role, Keng Hui was the Director of the Singapore
University of Technology and Design (SUTD)’s Digital Manufacturing & Design Centre (DManD), where he co-led the research centre to develop leading edge capabilities in digital manufacturing and computational design. Concurrently, he was also the Director of the National Additive Manufacturing Innovation Cluster ([email protected]), where he set up and led the translational research centre which focuses on additive manufacturing (AM) R&D with companies, standards development, and industry outreach.
Before SUTD, Keng Hui had held several key appointments in A*STAR. He was the
Deputy Executive Director of the National Metrology Centre (NMC), where he
managed research capability development, resource planning and talent development. He was also the Director of the SERC Engineering Cluster, where he established and managed large scale strategic initiatives, including pioneering programmes in the Future of Manufacturing (e.g. AM, robotics, remanufacturing, optical engineering, logistics & supply chain management), the national Marine & Offshore (M&O) programme, as well as the A*STAR Urban Systems and MedTech programmes. He also supported the establishment of the National Robotics Programme (NRP), A*STAR Technology Adoption Programme (TAP) and Technology Centre for Offshore & Marine Singapore (TCOMS).
Keng Hui was formerly the Head of Product Development at a manufacturing company; CTO and co-founder of a medical image diagnostics startup based on his inventionwith NUS and the National Skin Centre; CTO and co-founder of a medical imaging and robotics start-up in Boston based on his invention at MIT and the Massachusetts General Hospital; and research scientist at the National University Hospital.
Keng Hui is currently an adjunct professor in SUTD. He has served on national-level
R&D committees in advanced manufacturing, robotics and urban solutions, as well as standards committee in AM. He holds several patents, and was a recipient of the
Innovator’s Award from the Prime Minister’s Office for his MedTech work. He received his degrees from Imperial College, MIT and NUS.
Modelling and Simulation: Innovations to Solve Challenges in Data Centres
Data centers are increasingly important due to societal progress and technological advancement. The mobile wireless telecommunication industry’s progress from 4G to 5G is expected to bring about a significant capacity demand for data centers. In addition, moving towards Industry 4.0, cyber-physical systems’ interconnectivity will accelerate further the growth of data center. In view of the increasing criticality of data centers, it has to be protected against many disruptive factors, including heat build up. This is because electronic devices consume electricity and its natural byproduct is heat. In order to ensure reliable operation and satisfactory equipment lifetime, ambient temperature for electronics must be maintained within acceptable limits as temperature affects the performance of electronic systems in many ways. In this talk, I will share how modelling and simulation have been used to develop innovations to solve challenges in data centers, particularly in heat management. Those innovation successes are in collaboration with companies, research institutes, agencies and the academia. This includes server rack design, system modelling of refrigeration cycle and passive on-demand cooling system.
