Portland (PGI) – PGI Fortran, C and C++ compilers and tools

PGI compilers deliver the performance you need on CPUs, with OpenACC and CUDA Fortran for HPC applications development on GPU-accelerated systems. OpenACC and CUDA programs can run several times faster on a single Tesla V100 GPU compared to all the cores of a dual-socket server, and interoperate with MPI and OpenMP to deliver the full power of today’s multi-GPU servers.

Is your application 10s or 100s of thousands of lines of Fortran, C and C++ code? With OpenACC directives, you don’t have to parallelize all of it at once. You can identify hot loops and code regions using the PGI profiler, then incrementally parallelize and tune them one by one. OpenACC code remains 100% standard-compliant and portable to other compilers and platforms, and enables parallel processing on CPUs and GPUs using identical source code.

Performance Profiling and Optimization

The PGI Profiler is a powerful and easy-to-use interactive performance profiler for parallel programs written with OpenMP or OpenACC directives, or using CUDA. Use it to visualize and analyze the performance of your Fortran, C and C++ programs. The PGI Profiler can correlate execution time with procedures, source code and instructions, allowing you to quickly see where and how execution time is spent. Through resource utilization data and compiler feedback information, the PGI Profiler provides features that will help you understand why parts of your program have high execution times and how you can modify your source code or compiler options to improve performance. The PGI Profiler is included with all PGI products.

A Fortran-friendly Debugger

The PGI graphical debugger for Fortran, C and C++ supports of debugging serial and parallel programs including MPI, OpenMP and hybrid MPI/OpenMP applications. The PGI Debugger can debug programs on SMP workstations, servers, distributed-memory clusters and hybrid clusters where each node contains multiple multicore x86 processors. It allows you to control threads or processes individually or in groups, and allows you to examine state down to the register level. The PGI Debugger is also included with all PGI products with all PGI products for x86-64 platforms.

PGI Product Specifications

PGI Fortran is a native parallelizing/optimizing Fortran 2003 compiler with support for OpenMP 4.5 directive-based parallel programming for multicore CPUs, and OpenACC 2.6 directive-based parallel programming for CPUs and accelerators. The PGI Fortran compiler includes CUDA Fortran extensions targeting NVIDIA CUDA-enabled GPUs.

PGI C and C++ are native parallelizing/optimizing ANSI C11 and GNU-compatible C++17 compilers. Both compilers implement OpenMP 4.5 pragma-based parallel programming for multicore CPUs, and OpenACC 2.6 pragma-based parallel programming for CPUs and NVIDIA GPUs. The PGI C++ compiler is substantially compatible with GNU g++ releases through GCC 8.1. PGI Fortran supports the industry standard ISO_C_BINDING, which allows for easy argument passing and procedure invocation between Fortran, C, and C++.

Note: Effective with the PGI 2016 release, the PGI C++ compiler is no longer supported on Microsoft Windows.

All PGI products for x86-64 systems include the OpenMP and MPI enabled parallel PGI Debugger that can debug up to 16 local MPI processes. All PGI products also include the OpenMP and OpenACC parallel PGI Performance Profiler. All PGI products also include a precompiled OpenBLAS library, and for Linux x86-64, a precompiled MPI message passing library.

PGI products for both macOS and Windows consists of command-level versions of the PGI compilers and both command-level and graphical versions of the PGI Debugger and PGI Performance profiler. An integrated development environment (IDE) is neither provided nor supported.

PGI products target 64-bit x86 processor-based workstations, servers and clusters running Linux, macOS or Windows, and 64-bit OpenPOWER processor-based systems running Linux.
