SUMMARY:MS6B - Motif-Based Automated Performance Engineering for HPC
DESCRIPTION:Minisymposium\n\nWe will describe here domain-specific librari
 es (DSLs) that express mathematical/programming motifs (data objects and o
 perations on those data objects), along with software back-ends that trans
 late the library calls into high-performance code. By the use of a motif-a
 ware software stack, the scientific application code written is much small
 er than fully optimized code, with the applications-level code remaining u
 nchanged in moving between platforms, thus leading to a less expensive dev
 elopment process. The four talks being given cover multiple motifs, and di
 fferent approaches to supporting motif-based DSLs. (1) George Bisbas (ICL)
  will talk about an approach to structured-grid DSLs based on lowering the
  abstractions written in Python to the LLVM Multi-Level Intermediate Repre
 sentation (MLIR). (2) Het Mankad (CMU / ORNL) will talk about Proto / Prot
 oX, a DSL for the structured-grid motif that targets CPUs and GPUs, based 
 on the Spiral toolchain. (3) Sanil Rao (CMU) will talk about FFTX for supp
 orting FFTs on CPU and GPU systems, based on the Spiral toolchain. (4) Sam
  Reeve (ORNL) will talk about Cabana, a DSL for supporting grid free parti
 cle methods and hybrid particle / mesh methods on GPUs, based on the use o
 f the Kokkos run-time libraries for GPU parallelism.\n\nProtoX : A Code Ge
 neration Framework for Stencil Operations\n\nProtoX is a code generation f
 ramework for stencil and pointwise operations - the key components in nume
 rically approximating the solution to various partial differential equatio
 ns (PDEs). The frontend for ProtoX uses Proto - a C++ based domain specifi
 c library that provides a high level of abstracti...\n\n\nHet Yagnesh Mank

 ------\nFFTX, SpectralPack and Beyond\n\nWe present the design of the API 
 and runtime environment of FFTX as well as future project directions. FFTX
  is developed as part of the DOE ExaScale effort by LBL, Carnegie Mellon U

 le Particle and Structured-Mesh Simulation with Cabana\n\nWe present Caban
 a, a performance portable library for building scientific applications, in
 cluding mesh-free techniques from atomistic (molecular dynamics) to cosmol
 ogy (N-body), hybrid particle-mesh (e.g. particle-in-cell), and structured
  grid simulation. Cabana was created through the U.S. Departme...\n\n\nSam
