It started with dual-core processors supplanting single core processors. At that time, the world was changing as parallel programming was destined to be ubiquitous in the form of multicore processors. In 2007, we renamed our tools “Parallel Studio” to emphasize our support for parallelism. What happened to the Parallel Studio XE compilers?
Intel is committed long-term to LLVM, to help with ongoing innovation, and our relentless pursuit of industry leading optimizations. We encourage users to take advantage of the faster build times, higher levels of optimization, and new capabilities by moving now to our LLVM-based C/C++ compilers. Our LLVM-based compilers are where we will have support for SYCL, C++20, OpenMP 5.1, and OpenMP GPU target device support. To support Intel's evolving platforms, we are focusing new feature and hardware support in our LLVM-based compilers where we have added highly optimized support for GPUs and FPGAs alongside our continuing commitment to provide industry leading CPU optimizations. While the classic Intel C/C++ compiler shows a 18% advantage over gcc here, the LLVM-based Intel C/C++ compiler shows a 41% advantage. Intel C/C++ compilers have a history of offering leadership performance.

It’s time to upgrade the compiler you use! I share one examples here, and more of our measurements are included at the end of this blog. We also beat ourselves: the new LLVM-based Intel C/C+ compiler matches or exceed the Intel C/C++ classic compiler. Consistent with our objective to be the leading C/C++ compiler for Intel architecture, our measurements show Intel C/C++ compilers besting other options.

With the latest Intel C/C++ compilers, released with the Intel oneAPI toolkits versions 2021.3, we made a series of performance measurements. This is to be expected and is consistent with other compilers that have adopted LLVM. Not all our optimization techniques get upstreamed-sometimes because they are too new, sometimes because they are very specific for Intel architecture. We continue our strong history of contributing to the clang and LLVM projects, including optimizations for LLVM and clang. The default for the Intel C/C++ compilers going forward are versions (icx) that have adopted the LLVM open source infrastructure. The performance of the Intel C/C++ compilers can be expected to give higher performance than the base clang+LLVM compilers for Intel architecture. Intel contributes to LLVM projects directly, and we also have a staging area ( Intel project for LLVM technology) for SYCL support. Our active collaborations today include optimization report additions, expanded floating-point model support, and enhanced vectorization. Intel has a long history of contributing and supporting open source projects that includes a decade of contributions to LLVM. We all can appreciate that! We measured a 14% reduction in build times when using the Intel C/C++ compiler included in the Intel oneAPI 2021.3 toolkits. In addition to helping reduce build times, adoption of Clang has allowed us to contribute to, and benefit from, community efforts to support the latest C++ language standards. There are many benefits in adopting LLVM, but let’s start with faster build times. Clang is fast. LLVM, including Clang, are maintained by a large and very active development community. The Clang open source project provides a C/C++ frontend supporting the latest language standards for the LLVM project. The LLVM open source project is a collection of modular and reusable compiler and toolchain technologies supporting multiple processor architectures and programming languages. We are committed to making this as seamless as possible while yielding numerous benefits for developers who use the Intel compilers.
I will offer advice for upgrading from our classic compilers to our LLVM-based compilers. The benefits of adopting LLVM are numerous. While the Intel C/C++ compiler adoption of LLVM is complete, I will also share updates on the important (but not yet complete) Intel Fortran compiler adoption of LLVM. I’ll discuss what it means for users of the compilers, why we did it, and the bright future ahead. In this blog, I share information regarding our adoption of LLVM. The latest Intel C/C++ compilers, using LLVM, deliver faster compiler times, better optimizations, enhanced standards support, and support for GPU and FPGA offloading. LLVM helps us with our goal to offer the best C/C++ compilers for Intel architecture. The next generation Intel C/C++ compilers are even better because they use the LLVM open source infrastructure.
