SYCL & Compilers

SYCL

SYCL is an open alternative to single-architecture proprietary languages. It allows developers to reuse code across hardware targets (CPUs and accelerators such as GPUs and FPGAs) and also perform custom tuning for a specific accelerator. These code walkthroughs introduce you to basic principles and practices of SYCL programming. To continue to learn about SYCL and Intel’s integration of these new programming language into oneAPI Toolkits.

Intel Fortran and C++ Compilers

Create code that takes advantage of more cores and built-in technologies in platforms based on Intel® processors. Compile and generate applications for Windows*, Linux*, and macOS*. This compiler integrates seamlessly with popular third-party compilers, development environments, and operating systems. Build high-performance applications by generating optimized code for Intel® Xeon® Scalable processors and Intel® Core™ processors. Boost Single Instruction Multiple Data (SIMD) vectorization and threading capabilities (including for Intel® Advanced Vector Extensions 512 instructions) using the latest OpenMP* parallel programming model. IFX, Intel Fortran Compiler: provides CPU and GPU offload support. Features

Improves development productivity by targeting CPUs and GPUs through single-source code while permitting custom tuning.
Supports broad Fortran language standards.
Incorporates industry standards support for OpenMP* 4.5, and initial OpenMP 5.0 and 5.1 for GPU Offload
Uses well-proven LLVM compiler technology and Intel's history of compiler leadership.
Takes advantage of multicore, Single Instruction Multiple Data (SIMD) vectorization, and multiprocessor systems with OpenMP, automatic parallelism, and coarrays
Optimizes code with an automatic processor dispatch feature.

Libraries & MPI

Intel MPI Library

Intel® MPI Library is a multifabric message-passing library that implements the open-source MPICH specification. Use the library to create, maintain, and test advanced, complex applications that perform better on high-performance computing (HPC) clusters based on Intel® processors.

Develop applications that can run on multiple cluster interconnects that you choose at run time.
Quickly deliver maximum end-user performance without having to change the software or operating environment.
Achieve the best latency, bandwidth, and scalability through automatic tuning for the latest Intel® platforms.
Reduce the time to market by linking to one library and deploying on the latest optimized fabrics.

Math Kernel Library (oneMKL)

Intel Math Kernel Library (MKL): accelerate math procession routines, increase application performance, and reduce development time. MKL includes Linear algebra, fast flourier Transforms (FFT) Vector statistics and data fitting, vector math and miscellaneous solvers.

Profiling & Debugging

Intel Advisor

Intel Advisor: Is a design and analysis tool for achieving high application performance. This is done through efficient threading, vectorization, and memory use, and GPU offload on current and future Intel® hardware. The tool supports C, C++, Fortran, Data Parallel C++ (DPC++), OpenMP*, and Python*.
