Lawrence Livermore Announces a New Project to Study Numerical Integrity

New Tools will ensure that HPC software gives the same results across different hardware platforms.

A new project sponsored by the US Department of Energy and involving researchers from the Lawrence Livermore National Laboratory will address an important challenge for HPC computing: numerical integrity across hardware platforms. As high-performance computers become more complex and integrate new combinations of CPUs and GPUs, porting applications from one system to another can cause problems for numerical results. Software that runs on one system might not produce the same result on another system.

The new project, which is called “ComPort: Rigorous Testing Methods to Safeguard Software Porting,” will develop tools to test and validate whether results agree across different platforms, with the goal of finding ways to repair and improve software to maintain cross-platform numerical integrity.
