The Livermore Unstructured Lagrange Explicit Shock Hydrodynamics (LULESH) proxy
application [1] is being developed as part of the NNSA Advanced Scientific Computing (ASC) …

Parallel machines are becoming more complex with increasing core counts and more
heterogeneous architectures. However, the commonly used parallel programming models, C/C++ …

CORAL, the Collaboration of Oak Ridge, Argonne and Livermore, is fielding two similar IBM
systems, Summit and Sierra, with NVIDIA GPUs that will replace the existing Titan and …

… was done by Ian Karlin and Jim McGraw. Jeff Keasler and Ian Karlin created the pure C
version of the code. Ian Karlin is responsible for the transactional memory and critical section …

Data races in multi-threaded parallel applications are notoriously damaging while extremely
difficult to detect. Many tools have been developed to help programmers find data races. …

We present a computational framework for high-performance tensor contractions on GPUs.
High-performance is difficult to obtain using existing libraries, especially for many …

Efficient exploitation of exascale architectures requires rethinking of the numerical algorithms
used in many large-scale applications. These architectures favor algorithms that expose …

Tuning large applications requires a clever exploration of the design and configuration
space. Especially on supercomputers, this space is so large that its exhaustive traversal via …

The fat-tree topology is one of the most commonly used network topologies in HPC systems.
Vendors support several options that can be configured when deploying fat-tree networks …

We improved the quality and reduced the time to produce machine learned models for use
in small molecule antiviral design. Our globally asynchronous multi-level parallel training …
