Product : Fedora 34
Version : 4.4.0
Release : 2.fc34

Summary : An optimized libcint branch for X86 platform with SSE3 intrinsics
Description :
Qcint is a branch of the libcint library. It provides exactly the
same APIs as libcint. However, the code is optimized using AVX
instructions. On x86_64 platform, qcint can be 5 ~ 50% faster than
libcint. Please refer to libcint for more details of the features.
--------------------------------------------------------------------------------
Update Information:
qcint had been silently building with -march=native for an extended time; this
build fixes the issue by limiting to SSE3 instructions.
