https://bugzilla.redhat.com/show_bug.cgi?id=1753084 Bug ID: 1753084 Summary: Review Request: libdivide - Optimized integer division Product: Fedora Version: rawhide Hardware: All OS: Linux Status: NEW Component: Package Review Severity: medium Priority: medium Assignee: nobody@xxxxxxxxxxxxxxxxx Reporter: loganjerry@xxxxxxxxx QA Contact: extras-qa@xxxxxxxxxxxxxxxxx CC: package-review@xxxxxxxxxxxxxxxxxxxxxxx Target Milestone: --- Classification: Fedora Spec URL: https://jjames.fedorapeople.org/libdivide/libdivide.spec SRPM URL: https://jjames.fedorapeople.org/libdivide/libdivide-2.0-1.fc32.src.rpm Fedora Account System Username: jjames Description: This package contains a header-only C/C++ library for optimizing integer division. Integer division is one of the slowest instructions on most CPUs, e.g. on current x64 CPUs a 64-bit integer division has a latency of up to 90 clock cycles whereas a multiplication has a latency of only 3 clock cycles. libdivide allows you to replace expensive integer division instructions by a sequence of shift, add and multiply instructions that will calculate the integer division much faster. On current CPUs you can get a speedup of up to 10x for 64-bit integer division and a speedup of up to to 5x for 32-bit integer division when using libdivide. libdivide also supports SSE2, AVX2 and AVX512 vector division which provides an even larger speedup. -- You are receiving this mail because: You are on the CC list for the bug.
