What is Intel Application Migration Tool for OpenACC to OpenMP API? The Intel Application Migration Tool for OpenACC to OpenMP API is a Python3-based tool that helps developers to migrate OpenACC ...

The choice of programming tools and programming models is a deeply personal thing to a lot of the techies in the high performance computing space, much as it can be in other areas of the IT sector.

The source file shows how to use OpenACC to accelerate LBM, and includes a CUDA implementation of LBM to compare the performance. Compilation Don't use OpenACC acceleration: g++ 3D_LBM_Poiseuille.cpp ...

Abstract: OpenACC is gaining momentum as an implicit and portable interface in porting legacy CPU-based applications to heterogeneous, highly parallel computational environment involving many-core ...

Abstract: GPUs have become important solutions for accelerating scientific applications. Most of the existing work on climate models now use code rewritten using CUDA to achieve a limited speedup.

OpenACC is a directive based programming model that gives C/C++ and Fortran programmers the ability to write parallel programs simply by augmenting their code with pragmas. Pragmas are advisory ...

Since the beginnings of the Supercomputer era, users have been faced with the daunting task of rewriting their applications to take advantage of new next-generation machines. Performance just wasn’t ...

The Clacc project has developed OpenACC compiler, runtime, and profiling interface support for C/C++ by extending Clang and LLVM. A key Clacc design feature is that it translates OpenACC to OpenMP to ...

IEEE/ACM Workshop on the LLVM Compiler Infrastructure in HPC (LLVM-HPC) OpenACC was launched in 2010 as a portable programming model for heterogeneous accelerators. Although various implementations ...

We present preliminary results of a GPU porting of all main Gadget3 modules (gravity computation, SPH density computation, SPH hydrodynamic force, and thermal conduction) using OpenACC directives.

Not so long ago, there was a question whether exascale supercomputers would be built from a very large number of thin nodes containing only modest amounts of parallelism or a smaller number of fat ...
