MD vs. QC on GPUs

“Classical” Molecular Dynamics Quantum Chemistry (MO, PW, DFT, Semi-Emp)Simulates positions of atoms over time;

chemical-biological or chemical-material behaviors

Calculates electronic properties; ground state, excited states, spectral properties,

making/breaking bonds, physical properties

Forces calculated from simple empirical formulas (bond rearrangement generally forbidden)

Forces derived from electron wave function (bond rearrangement OK, e.g., bond energies)

Up to millions of atoms Up to a few thousand atoms

Solvent included without difficulty Generally in a vacuum but if needed, solvent treated classically (QM/MM)

or using implicit methods

Single precision dominated Double precision is important

Accelerating Discoveries

Using a supercomputer powered by the Tesla

Platform with over 3,000 Tesla accelerators,

University of Illinois scientists performed the first

all-atom simulation of the HIV virus and discovered

the chemical structure of its capsid — “the perfect

target for fighting the infection.”

Without gpu, the supercomputer would need to be

5x larger for similar performance.

Gaussian 16

GAUSSIAN 16

Using OpenACC allowed us to continue

development of our fundamental

algorithms and software capabilities

simultaneously with the GPU-related

work. In the end, we could use the

same code base for SMP, cluster/

network and GPU parallelism. PGI's

compilers were essential to the

success of our efforts.

Mike Frisch, Ph.D.President and CEOGaussian, Inc.

Parallelization Strategy

Within Gaussian 16, GPUs are used for a small fraction of code that consumes a large

fraction of the execution time. T e implementation of GPU parallelism conforms

to Gaussian’s general parallelization strategy. Its main tenets are to avoid changing

the underlying source code and to avoid modif cations which negatively af ect CPU

performance. For these reasons, OpenACC was used for GPU parallelization.

T e Gaussian approach to parallelization relies on environment-specif c parallelization frameworks and tools: OpenMP for shared-memory, Linda for cluster and network parallelization across discrete nodes, and OpenACC for GPUs.

T e process of implementing GPU support involved many dif erent aspects:

Identifying places where GPUs could be benef cial. T ese are a subset of areas which

are parallelized for other execution contexts because using GPUs requires f ne grained

parallelism.

Understanding and optimizing data movement/storage at a high level to maximize

GPU ef ciency.

Project Contributors

PGI Accelerator Compilers with OpenACCPGI compilers fully support the current OpenACC standard as well as important extensions to it. PGI is an important contributor to the ongoing development of OpenACC.

OpenACC enables developers to implement GPU parallelism by adding compiler directives to their source code, of en eliminating the need for rewriting or restructuring. For example, the following Fortran compiler directive identif es a loop which the compiler should parallelize:

! $ a c c p a r a l l e l l o o p

Other directives allocate GPU memory, copy data to/from GPUs, specify data to remain on the GPU, combine or split loops and other code sections, and generally provide hints for optimal work distribution management, and more.

T e OpenACC project is very active, and the specif cations and tools are changing fairly rapidly. T is has been true throughout the lifetime of this project. Indeed, one of its major challenges has been using OpenACC in the midst of its development. T e talented people at PGI were instrumental in addressing issues that arose in one of the very f rst uses of OpenACC for a large commercial sof ware package.

Specifying GPUs to Gaussian 16

T e GPU implementation in Gaussian 16 is sophisticated and complex but using it is simple and straightforward. GPUs are specif ed with

1 additional Link 0 command (or equivalent Default.Route f le entry/command line option). For example, the following commands tell

Gaussian to run the calculation using 24 compute cores plus 8 GPUs+8 controlling cores (32 cores total):

%CPU= 0 - 3 1 Request 32 CPUs for the calculation: 24 cores for computation, and 8 cores to control GPUs (see below). %GPUCPU= 0 - 7 = 0 - 7 Use GPUs 0-7 with CPUs 0-7 as their controllers.

Detailed information is available on our website.

PGI’s sophisticated prof ling and performance evaluation tools were vital to the success of the ef ort.
