Ensuring correctness in high-performance computing (HPC) applications

is one of the fundamental challenges that the HPC community faces

today. While significant advances in verification, testing, and

debugging have been made to isolate software errors (or defects) in the

context of non-HPC software, several factors make achieving correctness

in HPC applications and systems much more challenging than in general

systems software: growing heterogeneity (architectures with CPUs, GPUs,

and special purpose accelerators), massive scale computations (very

high degree of concurrency), use of combined parallel programing models

(e.g., MPI+X), new scalable numerical algorithms (e.g., to leverage

reduced precision in floating-point arithmetic), and aggressive

compiler optimizations/transformations are some of the challenges that

make correctness harder in HPC. The following DOE report lays out the key

challenges and research areas of HPC correctness:


As the complexity of future architectures, algorithms, and applications

in HPC increases, the ability to fully exploit exascale systems will be

limited without correctness. With the continuous use of HPC software to

advance scientific and technological capabilities, novel techniques and

practical tools for software correctness in HPC are invaluable.

The goal of the Correctness Workshop is to bring together researchers

and developers to present and discuss novel ideas to address the

problem of correctness in HPC. The workshop will feature contributed

papers and invited talks in this area.



Topics of interest include, but are not limited to:

* Formal methods and rigorous mathematical techniques for correctness in


* Program synthesis techniques for testing and debugging HPC applications

* Frameworks to address the challenges of testing complex HPC applications

(e.g., multiphysics applications)

* Approaches for the specification of numerical algorithms with the goal of

correctness checking

* Error identification in the design and implementation of numerical

using finite-precision floating point numbers

* Tools to control the effect of non-determinism when debugging and testing


* Scalable debugging solutions for large-scale HPC applications

* Scalable tools for model checking, verification, certification, or


* Static and dynamic analysis to test and check correctness in the entire

software ecosystem

* Predictive debugging and testing approaches to forecast the occurrence of

errors in specific conditions

* Machine learning and anomaly detection for bug detection and localization

* Correctness in emerging HPC programming models

* Analysis of software error propagation and error handling in HPC runtime

systems and libraries

* Metrics to measure the degree of correctness of HPC software

* Specifications to check the correctness of runtime systems

* Large databases of bug reports and/or reproducible test cases of HPC

* Benchmarks to test the effectiveness of HPC correctness tools



We expect that the proceedings will be archived in IEEE Xplore via TCHPC.
