Overview

• Intel® Parallel Studio XE 2020 Composer Edition for Fortran and C++ Linux* contains an update to the Intel® C++ Compiler next generation code generator. This is invoked using the -qnextgen option to the ICC and ICPC compilers. This update to the Intel® C++ Compiler next generation code generator includes our latest updates and features for our C++ next generation compiler invoked with the -qnextgen option.
• There are no new features, bug fixes, or security enhancements for the Intel® Fortran Compiler or the Intel® C++ Compiler without the -qnextgen option.
• This is a Linux only release.

Overview

• THIS IS A LINUX ONLY RELEASE.
• Intel® Parallel Studio XE 2019 update 7 Composer Edition contains compiler update 9.
• 2019 Update 7 provides a fix to the Intel® C++ Compiler related to the _mm_prefetch intrinsic. There was a problem in specific forms of SIMD loops with _mm_prefetch that under certain gather/scatter operations could cause a crash.  If you do not use the _mm_prefetch intrinsic then you will not see this potential crash.  

• There were a few security related enhancements to the license checking software used by the C++ and Fortran compilers.

• The compiler version will appear in the version string as version 19.0.9 in this PSXE 2019 Update 7.  This is due to compiler updates released outside of Parallel Studio packages that used compiler versions 19.0.7 and 19.0.8.  For details on compiler versions included in Parallel Studio releases please visit Intel Compiler and Composer Update Version Numbers to Compiler Version Number Mapping.
