Move `#include`s from `alpaka::cpu::detail` to the global namespace (see #1775). On Linux, query the OS for free pages instead of reading `/proc/meminfo` (see #1774). Replace the nested namespace with a...

move `#include`s outside of the `alpaka::cpu::detail` namespace

4

Depending on the architecture, the implementation of `alpaka::cpu::detail::cpuid()` may pull a system header in the `alpaka::cpu::detail` namespace: https://github.com/alpaka-group/alpaka/blob/f27d78c23c22f4eb5044a39cbfa60360ad1cd129/include/alpaka/dev/cpu/SysInfo.hpp#L42-L66 . Would it be possible to move the `#include` statements outside of...

replace reading from `/proc/meminfo` with call to `sysconf()`

2

On Linux, `getFreeGlobalMemSizeBytes()` is implemented parsing `/proc/meminfo`: https://github.com/alpaka-group/alpaka/blob/f27d78c23c22f4eb5044a39cbfa60360ad1cd129/include/alpaka/dev/cpu/SysInfo.hpp#L220-L245 I would suggest replacing it with reading the number of free pages from `sysconf()`, for example: ```c++ # if defined(_SC_AVPHYS_PAGES) return static_cast(sysconf(_SC_AVPHYS_PAGES))...

CI: refactor and extend atomic tests

2

clang CUDA is exposing `atomic*_block()` function signatures even if these can not be used by the selected architecture. This leads to compile issues if clang is used as CUDA compiler....

The unit test for `atomicDec` is not testing the flip around based on the values. https://github.com/alpaka-group/alpaka/blob/0b96515b1c8a24d0c3a2904081bc301311503770/include/alpaka/atomic/Op.hpp#L131 Some for `atomicInc` https://github.com/alpaka-group/alpaka/blob/0b96515b1c8a24d0c3a2904081bc301311503770/include/alpaka/atomic/Op.hpp#L115 We simply test if an value is incremented or decremented:...
