Optimizing Codes for Heterogeneous HPC Clusters Using OpenACC

July 3, 2017

Looking at the Top500 and Green500 ranks, one clearly realizes that most HPC systems are heterogeneous architecture using COTS (Commercial Off-The-Shelf) hardware, combining traditional multi-core CPUs with massively parallel accelerators, such as GPUs and MICs. With processor frequencies now hitting a solid wall, the only truly open avenue for riding today the Moore’s law is increasing hardware parallelism in several different ways: more computing nodes, more processors in each node, more cores within each processor, and longer vector instructions in each core.

Compilers and More: OpenACC to OpenMP (and back again)

June 29, 2016

In the last year or so, I’ve had several academic researchers ask me whether I thought it was a good idea for them to develop a tool to automatically convert OpenACC programs to OpenMP 4 and vice versa. In each case, the motivation was that some systems had OpenMP 4 compilers (x86 plus Intel Xeon Phi Knights Corner) and others had OpenACC (x86 plus NVIDIA GPU or AMD GPU), and someone wanting to run a program across both would need two slightly different programs. In each case, the proposed research sounded like a more-or-less mechanical translation process, something more like a sophisticated awk script, and that’s doomed from the start. I will explain below in more detail how I came to this conclusion. Read more…
