PGI 17.7 compilers for heterogeneous supercomputing now available

14 Sep 2017 Portland - Version 17.7 of the PGI 2017 Compilers and Tools is now available, delivering improved performance and programming simplicity to high-performance computing (HPC) developers who target multicore CPUs and heterogeneous GPU-accelerated systems.

Available immediately, key new features of the PGI 17.7 Compilers & Tools include:

  • Tesla V100 GPU support: PGI OpenACC and CUDA Fortran now support the new NVIDIA Volta GV100 GPU, offering more memory bandwidth, more streaming multiprocessors, next generation NVLink and new micro-architectural features that add up to better performance and programmability.
  • OpenACC for CUDA Unified Memory: the PGI 17.7 compilers leverage CUDA Unified Memory to simplify OpenACC programming on GPU-accelerated systems. When OpenACC allocatable data is placed in CUDA Unified Memory using a simple compiler option, no explicit data movement code or directives are needed.
  • OpenMP 4.5 for Multicore CPUs: Initial support for OpenMP 4.5 syntax and features allows the compilation of most OpenMP 4.5 programmes for parallel execution across all the cores of a multi-core CPU system. TARGET regions are implemented with default support for the multicore host as the target, and PARALLEL and DISTRIBUTE loops are parallelized across all OpenMP threads.
  • Automatic Deep Copy of Fortran Derived Types: Movement of aggregate, or deeply nested Fortran data objects between CPU host and GPU device memory, including traversal and management of pointer-based objects, is now supported using OpenACC directives.
  • C++ Enhancements: The PGI 17.7 C++ compiler includes incremental C++17 features, and is supported as a CUDA 9.0 NVCC host compiler. It delivers an average 20% performance improvement on the LCALS loops benchmarks.
  • Use C++14 Lambdas with Capture in OpenACC Regions: C++ lambda expressions provide a convenient way to define anonymous function objects at the location where they are invoked or passed as arguments. Starting with the PGI 17.7 release, lambdas are supported in OpenACC compute regions in C++ programmes, for example to drive code generation customized to different programming models or platforms. C++14 opens doors for more lambda use cases, especially for polymorphic lambdas. Those capabilities are now usable in OpenACC programmes.
  • Interoperability with the cuSOLVER Library: call optimized cuSolverDN routines from CUDA Fortran and OpenACC Fortran, C and C++ using the PGI-supplied interface module and the PGI-compiled version of the cuSOLVER library bundled with PGI 17.7.
  • PGI Unified Binary for NVIDIA Tesla and Multicore CPUs: use OpenACC to build applications for both GPU acceleration and parallel execution on multicore CPUs. When run on a GPU-enabled system, OpenACC regions offload and execute on the GPU. When run on a system without GPUs installed, OpenACC regions execute in parallel across all CPU cores in the system.
  • New Profiling features for CUDA Unified Memory and OpenACC: The PGI 17.7 Profiler adds new OpenACC profiling features including support on multi-core CPUs with or without attached GPUs, and a new summary view that shows time spent in each OpenACC construct. New CUDA Unified Memory features include correlating CPU page faults with the source code lines where the associated data was allocated, support for new CUDA Unified Memory page thrashing, throttling and remote map events, NVLink support and more.

Other features and enhancements of PGI 17.7 include comprehensive support for environment modules on all supported platforms, prebuilt versions of popular open source libraries and applications, and new "Introduction to Parallel Computing with OpenACC" video tutorial series. You can visit the PGI website for a complete list of PGI 17.7 features and capabilities.

PGI 17.7 is available for download today to all PGI Professional customers with active maintenance.
