compiler versions are
* GNU (gcc/libstdc++) 7
-* LLVM (clang/libc++) 5
-* Microsoft (MSVC) 2017 15.7
+* LLVM (clang/libc++) 8
+* Microsoft (MSVC) 2019
Other compilers may work (Cray, Pathscale, older clang) but do
not offer competitive performance. We recommend against PGI because
it works because we have tested it.
Every commit in our git source code repository
is currently tested with a range of configuration options on x86 with
-gcc versions 7 and 8,
-clang versions 8 and 9,
+gcc versions including 7 and 11,
+clang versions including 8 and 13,
+CUDA versions 11.0 and 11.4.2,
and
a version of oneAPI containing Intel's clang-based compiler.
-For this testing, we use Ubuntu 18.04 or 20.04 operating system.
+For this testing, we use Ubuntu 20.04 operating system.
Other compiler, library, and OS versions are tested less frequently.
