Reading AMDGCN ISA
- 13 May 2024
For an application developer it is often helpful to read the Instruction Set Architecture (ISA) for the GPU architecture that is used to perform its computations. Understanding the instructions of the pertinent code regions of interest can help in debugging and achieving performance optimization of the application.
Application portability with HIP
- 26 April 2024
Many scientific applications run on AMD-equipped computing platforms and supercomputers, including Frontier, the first Exascale system in the world. These applications, coming from a myriad of science domains, were ported to run on AMD GPUs using the Heterogeneous-compute Interface for Portability (HIP) abstraction layer. HIP enables these High-Performance Computing (HPC) facilities to transition their CUDA codes to run and take advantage of the latest AMD GPUs. The effort involved in porting these scientific applications varies from a few hours to a few weeks and largely depends on the complexity of the original source code. Figure 1 shows several examples of applications that have been ported and the corresponding porting effort.
C++17 parallel algorithms and HIPSTDPAR
- 18 April 2024
The C++17 standard added the concept of parallel algorithms to the
pre-existing C++ Standard Library. The parallel version of algorithms like
std::transform
maintain the same signature as the regular serial version,
except for the addition of an extra parameter specifying the
execution policy
to use. This flexibility allows users that are already
using the C++ Standard Library algorithms to take advantage of multi-core
architectures by just introducing minimal changes to their code.
