Overview

Do you want to help aerospace engineers solve problems faster? Does the phrase “nonlinear partial differential equations used for unsteady computations” excite you? Do you want to try yourself with the complex computational software that NASA scientists use? This might be the challenge for you.

NASA’s Aeronautics Research Mission Directorate (ARMD) is responsible for developing technologies that will enable future aircraft to burn less fuel, generate fewer emissions and make less noise.  Every U.S. aircraft and U.S. air traffic control tower has NASA-developed technology on board. It's why we like to say, NASA is with you when you fly!

We need to increase the speed of computations on the Pleiades supercomputer, specifically for computational fluid dynamics, by orders of magnitude, and could use your help!

This isn’t a quest for the faint of heart. As a participant, you’ll need to gain access to FUN3D software through an application process with the US Government.  Although this software usually runs on the Pleiades supercomputer, you can download and run it locally after applying HERE.

Background

NASA’s Aeronautics Research Mission Directorate (ARMD) is tasked with innovating at the cutting edge of aerospace.  Their work includes Innovation in Commercial Supersonic Aircraft, Ultra-efficient Commercial Vehicles and Transitioning to Low-Carbon Propulsion while also supporting the development of launch vehicles and planetary entry systems.  These strategic thrusts are supported by advanced computational tools, which enable reductions in ground-based and in-flight testing, provide added physical insight, enable superior designs at reduced cost and risk, and open new frontiers in aerospace vehicle design and performance.

The advanced computational tools include the NASA FUN3D software which is used for solving nonlinear partial differential equations, known as Navier-Stokes equations, used for steady and unsteady flow computations including large eddy simulations in computational fluid dynamics (CFD). Despite tremendous progress made in the past few decades, CFD tools are too slow for simulation of complex geometry flows, particularly those involving flow separation and multi-physics (e.g. combustion) applications. To enable high-fidelity CFD for multi-disciplinary analysis and design, the speed of computation must be increased by orders of magnitude.

NASA is seeking proposals for improving the performance of the NASA FUN3D software running on the NASA Pleiades supercomputer.  The desired outcome is any approach that can accelerate calculations by a factor of 10-1000x without any decrease in accuracy and while utilizing the existing hardware platform.

This challenge is being supported by HeroX and Topcoder and proposals are being accepted for 2 separate opportunities:

1. Ideation (this page) - Ideas and approaches may include, but are not limited to exploiting algorithmic developments in such areas as grid adaptation, higher-order methods and efficient solution techniques for high performance computing hardware.  Ideation responses can be submitted by clicking the accept challenge button above.
2. Architecture (Topcoder) - Optimize individual software module code and inter-node processing in order to reduce overall model computation time and parallelization efficiency is the goal of this second challenge.   Ideal submission may include algorithm optimization of the existing code base, Inter-node dispatch optimization or a combination of the two.  Unlike the Ideation challenge, which is highly strategic, this challenge focuses on measureable improvements of the existing FUN3D suite and is highly tactical.   See Topcoder for full details.

FUN3D Software:

Description-

The FUN3D software is written predominantly in Modern Fortran. The software is evolving

steadily in multi-language directions for reasons other than performance. Currently, a standard

computational task in the CFD area takes from thousands to millions of computational

core-hours.

FUN3D is:

• Code developed by the US Government at US taxpayer expense
• Flow analysis solver is written in Fortran, other components are written in C++ and Ruby
• Code which can be applied to a wide range of fluid dynamic problems, and
• Has a number of code features which represent leading-edge technology
• Is export controlled research code

Instructions to Request FUN3D-

FUN3D can be requested at https://software.nasa.gov/software/LAR-18968-1

FUN3D Application Guidance

• FUN3D has strict export laws so only US citizens may apply for the software and compete in this challenge. 

• Use only personal non-affiliated emails like Gmail or Yahoo.  Company or .edu emails should not be used since you are competing as an individual and they imply affiliation.
• There is a question in the application that asks you to explain the purpose for which the software is to be used.   You may simply put:  “HeroX HPFCC Challenge”
• You should plan to install the Fun3D on your own computer, NOT one provided by your company or school.  
• No other individuals besides yourself should be using this software and you should answer affirmative to the question asking if it will be used in-house only.
• You should use your full name for the recipient (Company/ University) Name question.
• Once your request has been accepted you will get an email notification informing you will need to sign the  Software User Agreement.   Once you log back into the NASA Software portal and you should see your request in the Pending state, there will be “action” button with an option to sign the SUA.   This does not mean your application is complete.  Once you sign, the final step is to verify your address.
• Once you sign the Software agreement (SUA) you will be sent a letter via the US mail which will contain a passcode.    You may respond to the email provided in the letter and include the passcode.  After you send the email which includes the passcode you should receive instructions to download the software within one business day.

You will need to get started on this right away, as this approval process will take several weeks.  While you are waiting for the software request to be processed you can download and read the FUN3D documentation and manual.  

NASA Pleiades supercomputer:

The FUN3D software is typically run on the NASA Pleiades supercomputer.  Pleiades is a distributed-memory Silicon Graphics Inc. SGI ICE cluster connected with InfiniBand® in a dual-plane hypercube technology.

Pleiades Current System Architecture

• 161 racks (11,472 nodes)
• 7.25 Pflop/s peak cluster

• 132 Tflop/s HPCG rating
• Total CPU cores: 246,048
• Total memory: 938 TB

Information about Pleiades can be found here.

Ideation Challenge Overview

The High Performance Fast Computing Challenges is about optimizing source code to improve NASA’s FUN3d Computational Fluid Dynamics suite in such a way that flow analysis that previously took months to compute can now be done in days or even hours.  We are hoping this challenge will identify ideas that will improve FUN3D to complete complex flow analysis 1000x faster.  We think there are several approaches to finding solutions that will help NASA achieve 1000x performance improvement and they don’t all require you to be an aeronautical engineer.  Ideas and approaches may include, but are not limited to exploiting algorithmic developments in such areas as grid adaptation, higher-order methods and efficient solution techniques for high performance computing hardware.
