Advisory Committees

CISL HPC Allocations Panel

CISL's advisory panel on high-performance computing and services is the CISL HPC Allocations Panel (CHAP). The CHAP's primary responsibility is to assess the merit of large computing requests for CISL supercomputers and related resources.

The panel accepts computing proposals from U.S. university researchers in the atmospheric and closely related sciences who are supported by the National Science Foundation (NSF). The CHAP recommends action with respect to a prospective user's request on the basis of the computational experimental design, computational effectiveness, and availability of computing resources.

CHAP members, most of whom are from the university community, are appointed to three-year terms by the CISL Director. Meetings are scheduled twice a year, usually in May and October. NSF's program coordinator for the NCAR and Facilities Section attends the semi-annual meetings and provides guidance from the NSF.

Bryan Lawrence (Chair), NCAS, University of Reading

Bryan Lawrence holds a Chair in Weather and Climate Computing at the University of Reading. He also leads on issues to do with models and data within the UK National Centre for Atmospheric Science (NCAS), is Project Scientist for the European Network for Earth Simulation (ENES), and has previously been Director of the UK Centre for Environmental Data Analysis (CEDA). Amongst other board roles, he is chair of the HPC Strategy Committee for the UK Natural Environment Research Council (NERC), represents NERC in HPC procurement, and chairs the CEDA/JASMIN board (and currently leads the JASMIN supercomputing project).

He still imagines he is a climate scientist, but in practice never gets to do any hands-on climate science - beyond what is done by his graduate students and staff - as most of his time is now devoted to solving workflow issues in climate modelling (from HPC provision to software infrastructure and data systems). Bryan has been on the CISL advisory panel since 2016, and has been chair since 2019. More information:

Nan Rosenbloom, NCAR/CGD

I am a project manager for CATALYST, an NCAR-DOE cooperative agreement. I am also a member of the Climate Change Research section within the Climate and Global Dynamics Laboratory. In this role I provide scientific, technical and organizational support for multiple projects within the section. One of my primary technical roles is to implement and support scientific model simulations using the CESM model. These runs are conducted on platforms at multiple High Performance Compute centers including the Texas Advanced Computing Center (TACC), the Argonne Leadership Computing Facility (ALCF), and the National Energy Research Scientific Computing Center (NERSC), as well as NCAR’s NCAR-Wyoming Supercomputing Center (NWSC).

Recent projects include orchestrating and conducting ensembles of high resolution (1⁄4 deg atm + (1 deg or 10th deg ocean)) CESM experiments for the International Laboratory for High-resolution Earth System Prediction (iHESP) project. Analysis of these high resolution simulations focuses on the effect of climate change on the frequency, duration and distribution of mid-latitude storm tracks and tropical cyclones. I also conduct low-resolution (1 deg) model ensembles with the CESM2 version of the model that focus on the effects of regionally forced ocean temperatures on climate variability and decadal predictability.
