HPC-servere vokser raskt, ikke bare for x86 men også for OpenPOWER, ARM og GPU akseleratorer. PGI Fortran, C/C++ kompilatorer og OpenACC er designet for å levere høy ytelse på alle disse prosessorene. PGI tilbyr kompilatorer for x86 og GPU'er med OpenACC parallellisering over alle kjerner på flerkjerners CPU'er og GPU'er. PGI og OpenACC leverer ytelsen du trenger idag og fleksibiliteten du trenger imorgen.

PGI har nylig endret på sin sammensetting av lisenser. Lisensen som Alfasoft og PGI anbefaler heter PGI Professional Edition, og er en evigvarende (perpetual) lisens som inneholder både nye og tidligere versjoner av PGI Fortran, C og C++ kompilator for flerkjerners CPU'er og NVIDIA Tesla GPU'er, inkludert OpenACC, OpenMP og CUDA Fortran funksjoner. PGI Professional Edition passer alle typer brukere, fra den enkeltstående utvikleren til HPC-eksperter, som behøver markedsledende kompilatorer og støtte for å optimalisere sin produksjonsutvikling.

PGI Compilers

On Intel Haswell CPUs with OpenMP, PGI delivers multicore performance more than 50% faster than the latest GCC compilers. That’s like buying a cluster with 50% more compute nodes. PGI compilers deliver world-class multicore CPU performance and accelerator programming features that can dramatically increase the performance of applications on GPU accelerators.

Accelerate Your Code with OpenACC
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 PGPROF 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.

PGI Supports All Major HPC Platforms
HPC servers are quickly expanding beyond multicore x86 CPUs to OpenPOWER, ARM and GPU accelerators. PGI Fortran, C and C++ compilers and OpenACC are designed to deliver high performance on all of these processors. PGI compilers for x86 and GPUs are available now, including OpenACC parallelization across all cores of a multicore CPU or a GPU. The Beta Evaluation Program for PGI compilers on OpenPOWER CPUs coupled to NVIDIA Tesla GPUs is coming this summer. PGI and OpenACC deliver the performance you need today, and the flexibility you need tomorrow. PGI compilers can take you there.

PGI multiple plattform support

Performance Profiling and Optimization
PGPROF is a powerful and easy-to-use interactive performance profiler for parallel pro- grams written with OpenMP or OpenACC directives, or using CUDA. Use PGPROF to vi- sualize and analyze the performance of your Fortran, C and C++ programs. PGPROF 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, PGPROF provides features that will help you under- stand why parts of your program have high execution times and how you can modify your source code or compiler options to improve performance. PGPROF is included with all PGI products.

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

PGI Support

The PGI Support Service entitles the subscriber to new licenses for new releases. Typically, support is valid for one year from date of purchase. New license purchases include 30 days of support service. If you did not purchase support when you purchased your license, or if your support has expired, you can qualify for the current relase by bringing your suport current.

PGI Support includes the following:

  • Ongoing technical support by electronic mail. Support requests may be sent by fax to +1-503-682-2637, or online using the PGI technical support request form.
  • Release updates for licensed product(s) at no additional cost, except for any administrative fee that may apply.
  • Full license fee credits on product upgrades, except for any administrative fee that may apply. "Product upgrades" refer to exchanging one product license for a more expensive product license, and is not the same as a version or "Release" upgrade referenced above.
  • Full license fee credits on user-count upgrades, except for any administrative fee that may apply.
  • Support subscriber-only forums and other services available at
  • Support subscriber-only special offers, discounts and promotions.


PGI is offered in three different editions:

PGI Community Edition – PGIs unsupported version of the PGI compilers including essentially all features of our previous PGI Accelerator Fortran/C/C++ Workstation product, but with a license-to-use that is limited to 1 year from the date of release.  CE is now available for Linux, OpenPOWER and Mac.  A Windows version may be available at a later date. 

PGI Professional Edition – PGIs recommended compiler for professional users. A perpetual license to current and all previous releases of the PGI Fortran, C and C++ compilers and tools for multicore CPUs and NVIDIA Tesla GPUs, including all OpenACC, OpenMP and CUDA Fortran features. Enables development of performance-portable HPC applications with uniform source code across the most widely used parallel processors and systems.  The PGI Professional Edition is for HPC experts who need cutting edge compilers and support for production software development.

PGI Enterprise – For large organizations that want a site-wide license and Premier Services, PGI also offer this annual, unlimited seat-count license.

A perpetual license to current and all previous releases of the PGI Fortran, C and C++ compilers and tools for multicore CPUs and NVIDIA Tesla GPUs, including all OpenACC, OpenMP and CUDA Fortran features. Enables development of performance-portable HPC applications with uniform source code across the most widely used parallel processors and systems.

Offers technical support with frequent PGI updates that include the latest PGI feature enhancements, performance improvements and bug fixes. The PGI Professional Edition is for HPC experts who need cutting edge compilers and support for production software development.

The price for an Academic license of PGI Professional Edition is discounted with 50% compared to a commercial license.


All PGI Professional Edition licenses are permanent and perpetual—they never stop working with the PGI release version for which they were created. FlexNet-managed licenses also work with all earlier PGI release versions back to 7.2. Except as noted below, all PGI permanent licenses are specific to individual PGI products running on a single operating system (e.g. PGI Fortran/C/C++ Workstation for Linux).

Node-Locked licenses restrict use to a particular host and one user at a time. They are very useful when a number of users want to share a PGI product. Node-locked licenses for x86 systems require the license service (lmgrd) run on the same machine the compilers are run. Executables can run on any other compatible machine. Node-locked licenses for OpenPOWER use a proprietary licensing scheme.

Floating licenses allow the license service to run on a machine different from the machines running the compilers. Floating licenses allow a mix of system types running different operating systems. The maximum number of concurrent users is determined by counting usage across all of the systems running the PGI compilers. Floating licenses usually require only a single license server. Users with floating licenses can "borrow" seats for out-of-office compiling.
