High-Performance Computing Working Group at the IMAG/MSM
Working Group Lead:Ravi Radhakrishnan
Research problems in the domain of biological and biomedical sciences and engineering often span multiple time and length-scales from the molecular to the organ/organism, owing to the complexity of information transfer underlying biological mechanisms. Multiscale modeling (MSM) and high-performance scientific computing (HPC) have emerged as indispensable tools for tackling such complex problems. However, a paradigm shift in training is now necessary to leverage the rapid advances, and emerging paradigms in HPC (see Figure 1) --- GPU, cloud, exascale supercomputing, quantum computing --- that will define the 21stcentury.

A summary of the 2019 ML-MSM symposium organized by MSM/IMAG can be found below, including video recordings of the webcast. A perspectives article published in 2019 on this meeting can be found under reports and review articles, below.
8. Advisory Committee to the NIH Director (ACD*) Workshop (2019)
Report from NIH data science infrastructure and NIH AI working group
ACD meeting is videocast: https://videocast.nih.gov/
*Background: The ACD functions a bit like an Institute Council for all of NIH and meets twice a year. ACD does not review grants, but they do review trans-NIH concept clearances.
The purpose of this working group is to initiate discussion, foster collaboration, and provide training resources for utilization of HPC methods and platforms:
- Computational resources, including high-performance computing
- Integrated multiscale modeling (MSM) and artificial intelligence (AI) based simulations on emerging computer architectures (Figure 1)
- Computational algorithms, libraries, tool-kits, and software
- Infrastructure and strategies to handle big-data problems
- Webinars on High Performance Computing Topics
- Workshops on HPC
- Collaborations and training for HPC
High-performance computing (HPC) broadly involves the use of new architectures (such as GPU computing), computing in distributed systems, cloud-based computing, and computing in parallel to massively parallel platforms or extreme hardware architectures for running computational models. The term applies especially to systems that function with large floating-point operations per second (teraflops 10^12, petaflops 10^15, exaflops 10^18) regime or systems which require extensive memory. HPC has remained central to applications in science, engineering, and medicine. Challenges for researchers utilizing HPC platforms and infrastructure range from understanding emerging new platforms to optimizing algorithms in massively parallel architectures to efficient access and handling of data at a large scale. The high-performance computing working group is focused on addressing contemporary HPC related issues faced by biomedical researchers.

Topic: Computing Hardware Resources
- Need for access to computing resources for MSM needs
- GPUs and other emerging computer hardware for MSM
- MSM and AI on the Cloud
Topic: Computational Algorithms
- Tool-kits, code, data for MS/AI on HPC platforms

Topic: Collaborate, define the needs of the community
- 20% of all computing time on NSF supercomputers and 10% of time on DOE supercomputers is used by NIH funded PIs. Would it benefit to coordinate the access to supercomputers, especially for small to medium sized or beginning users?
- Is there benefit of organizing focused workshops to discuss and exchange ideas related to HPC and MSM?
