Application of Performance Analysis Tools on SNL ASC Codes
This milestone 1) exercised a broad set of performance profiling and analysis tools, including tools whose development has been promoted by the ASC program; 2) exercised the tools on two different SNL ASC codes, one Sierra code (Sierra/Aria, a C++ codebase) and one RAMSES code (ITS, a Fortran codebase); and 3) exercised the tools on multiple platforms, including the CTS-1 (e.g., Serrano) and ATS-1 Trinity (e.g., Mutrino) platforms. The milestone generated a plethora of strong and weak scaling, trend and profile data for multiple versions and problem cases for each of the two codes. A wealth of experience was gained with the various tools that included identification of problems, an improved understanding of feature sets, enhanced usage documentation, and insights for future tool-development. Results are provided from a large number and variety of performance analysis runs with the target codes, together with instructions for how to make use of the tools with the codes.
FY17 ASC P&EM L2 Milestone 6009: Demonstrate Thread Scalability within Aria on Both Sides of Trinity
The use of next-generation platforms (NGPs), also known as advanced technology systems (ATS), that incorporate many-core and heterogeneous architectures for scientific computing represent a tectonic shift in computing hardware design that will require massive development work within the Sierra applications to harness these systems to their full potential. The completion of this milestone represents a first step towards this effort by threading many of the computational kernels within Sierra/Aria.
