Code Together

Building Cross-architecture, Cross-vendor Tools for HPC Application Developers

Just as a carpenter needs tools to build a house, a developer needs tools to write code and programs. This often means relying on other coders to develop tools and building on that foundation. Xiaozhu Meng, a research scientist at Rice University shares the progress of the HPC Toolkit Project. It’s focused on performance tuning – to help with problems like how to map the performance numbers from machine-code back to a higher-level programming language construct; or for GPUs, doing fine-grained management to manage performance inside kernels. He also discusses exascale computing, and how oneAPI fits in the mix for tools to help developers. Listen in. [20:30]

Advancing Bioinformatics with Modern Hardware, HPC Compute + Software

Bioinformatics is advancing health-care research by using computation to understand biological data. It’s useful for large complex data sets used in determining gene and protein functions, establishing evolutionary relationships, and predicting 3D shapes of proteins. Two experts, Sergio Santander-Jimenez at University of Extremadura, and Ricardo Nobre of INESC-ID, are combining the power of modern hardware (CPUs+GPUs), HPC compute, and software to advance bioinformatics applications in areas including epistasis detection

Inspiring the Next Generation of Scientists & Coders

The next generation of scientists and coders need more than a love of science and technology. The use of supercomputers in digital design to simulation pose opportunities solving the world’s biggest questions. Katherine Riley, director of science for Argonne’s Leadership Computing Facility, and Joe Curley, Intel senior director of oneAPI products, solutions and ecosystem, share what inspires them, and the unique characteristics to thrive in these careers. “It’s not just nerds working on ones and zeros, but we’re out to try to make a better planet.”

Extending the Roofline Model

INESC-ID researchers Aleksandar Ilic and Diogo Augusto Pereira Marques reveal their journey in extending Roofline Modeling for use in application optimization, known as the Cache-aware Roofline Model, or CARM, which has been incorporated into the Intel® Advisor tool and recognized with an award from the HiPEAC community in Europe. They are now taking this model further, tackling different types of devices, including CPUs and GPUs, with the help of DPC++. Using CARM, developers can detect bottlenecks in their code and derive strategies to squeeze maximum performance out of their architecture.
