Page 1 of 5. Featured Compiler Comparison. The AOCC environment provides various options to developers when building and optimizing C, C++, and Fortran applications targeting 32-bit and 64-bit Linux® platforms. Meanwhile in the timed PHP compilation test, AOCC 1.1 ended up being much slower than LLVM Clang and was in line with the GCC build performance. A scalar optimizing compiler has a really good day when it gets an optimization that boosts performance by 5%. But AOCC performing well here is good to see as generally Clang's OpenMP performance still lags behind the GNU Compiler Collection. AMD AOCC 1.1 Shows Compiler Improvements vs. GCC vs. Clang. All available versions of AOCL can be found by running the following command on a dev node. The Libraries can work with either AOCC or GCC compilers.

You can also contribute to Phoronix through a PayPal tip. state towards the end of last year compared to an LLVM Clang 11 base used by AOCC 2.3. DragonEgg is the primary Fortran frontend for AOCC. Legal Disclaimer, Privacy Policy | Contact. In the tests, which you can see below, AOCC offers higher performance than GCC in most cases, LLVM Clang in some cases, and marginally higher performance than LLVM Clang in some cases. LLVM Clang 9.0 SVN - The current development code of LLVM/Clang 9.0 as set to be released in a few weeks time and has been under feature freeze already. AOCC 3.0 is also tuned for AMD's AMDLibM 3.7 math library, improves its FLANG-based Fortran compiler Sandy Bridge Compiler Tests . Using the top-end AMD EPYC 7742 in a 2P Linux server configuration, here are C/C++ compiler benchmarks looking at the performance when built by the GNU Compiler Collection (GCC), LLVM Clang, and AOCC 2.0.

With the GraphicsMagick OpenMP-threaded image manipulation tests, AOCC 1.1 was faster than the tested Clang compilers but not quite as fast as GCC. A few days ago we found out that at the end of 2017 AMD quietly released their AOCC 1.1 C/C++ compiler. 28 Aug 10:10. 4. AMD AOCC 2.0 - The new AMD Optimizing C/C++ Compiler release introduced this week. Previous article RPCS 3 performance boost with Vulkan API – Comparison Video DirectX12 Vs Vulkan. 2. is it need to use build on AMD zen cpu or build on any x86 cpu, just run on AMD cpu.

If multiple "O" options are used, with or without level numbers, the last such option is the one that is effective. Unfortunately in the AVX-heavy Himeno pressure solver benchmark, AOCC 1.1 performance is notably regressed compared to upstream Clang 6.0. Each gcc binary roughly corresponds to the information which is embedded inside a single ToolChain. AOCC 3.0 is also tuned for AMD's AMDLibM 3.7 math library, improves its FLANG-based Fortran compiler support, offers improvements around OpenMP debugging, and other changes. WhatsApp. AMD AOCC 1.1 Compiler GCC LLVM Clang Benchmarking. But AOCC performing well here is good to see as generally Clang's OpenMP performance still lags behind the GNU Compiler Collection. Ubuntu 17.10 - 4.16.0-999-generic - … The mission at Phoronix since 2004 has centered around enriching the Linux hardware experience. 8 Systems - 75 Benchmark Results. DragonEgg that comes with AOCC works with gcc-4.8.2, can target the x86-32/x86-64 and has been successfully tested on various Linux platforms. Featured Compiler Comparison. The compiler benchmarks for this AMD EPYC 7742 2P testing from Ubuntu 19.04 with Linux 5.2 includes: GCC 9.1.0 - The current stable compiler release of the GNU Compiler Collection as introduced earlier this year.

AOCC 1.1 Install Guide Contents AOCC 1.1 Install Guide o Installing AOCC on Linux o Supported Operating systems o Known issues and limitations “AMD Optimizing C/C++ Compiler” - abbreviated as AOCC is a highly optimized C, C++ and Fortran compiler … Using the top-end AMD EPYC 7742 in a 2P Linux server configuration, here are C/C++ compiler benchmarks looking at the performance when built by the GNU Compiler Collection (GCC), LLVM Clang, and AOCC 2.0. A SOC-FWD is a tailored, operational- level headquarters (HQ) that provides a forward-deployed, persistent presence, C2 c Written by Michael Larabel in Software on 30 January 2018. AOCC 3.0 is the first AMD compiler release with Zen 3 optimizations, using the same -march=znver3 option of course as upstream LLVM and GCC. Interesting how AMD's compiler sometimes does significantly worse than LLVM and/or GCC. Snaps Are Quite Fantastic, For Some Use Cases; 8 Must-Try Open Source ERP Systems; Best Linux Distribution of 2020: Linux Mint 20; Telegram to Start Putting Ads in Public Channels in 2021 During all tests, the CFLAGS/CXXFLAGS were set to "-O3 -march=znver2" for targeting the Zen 2 EPYC processors. BUSINESS AVIATION PRIVATE OPERATION VS COMERCIAL. All rights reserved. With the GraphicsMagick OpenMP-threaded image manipulation tests, AOCC 1.1 was faster than the tested Clang compilers but not quite as fast as GCC. Phoronix: AMD AOCC 1.3 Compiler Benchmarks vs. GCC 8.2 vs. LLVM Clang 7.0 Earlier this month marked the release of the AMD Optimizing C/C++ Compiler 1.3 (AOCC 1.3) with a re-base to the LLVM 7.0 code-base, enhanced loop optimizations, better vectorization, code generation, integration of the optimized AMD Math Library, and AOCL are a set of numerical libraries specifically tuned for AMD EPYC processor family. AOC in France also designates wines (and foods, such as cheese) as the highest category and control by which a product was pro… This AOCC 1.3.0 is based on LLVM 7.0 release (llvm.org, 19th Sep 2018) and enhanced with various high-level optimizations. Ads are what have allowed this site to be maintained for the past 16 years. The default is "-O2").
