What is Loci-Stream?


The Loci-Stream code is a product of the coupling of a CFD flow solver(Stream) to an open-source parallel-computing framework (Loci). Together the two components make up the Loci-Stream code. The Loci framework is a highly scalable framework that powers the Stream solver to run on large scale machines with thousands of processors. Loci-Stream is designed to take advantage of existing commercially available front-end technology (standard grid generators) and back-end technology (post-processing software such as Tecplot, FieldView, EnSight etc.) which is relatively inexpensive compared to proprietary pre-processing and post-processing software provided by the major CFD vendors.   The flowchart below illustrates how typical users interact with Loci-Stream during a simulation workflow.



What is Loci?

Modern high performance clusters are powerful, but robust and reliable software for high performance clusters is difficult to create and expensive to maintain. The Loci programming framework developed at Mississippi State by Dr. Ed Luke shrinks the gap between high performance coding and physics modeling. The Loci framework is a multidisciplinary approach that maps complex mathematical models onto high performance computing architectures providing for maintainable high performance simulation software.
