Note: CUTLASS 3x increases the host compiler requirements to C++17. However, certain
|
|
existing integrations of CUTLASS require C++11 host compilers.
|
|
|
|
Until this requirement can be lifted, certain headers with this annotation are required
|
|
to be remain consistent with C++11 syntax.
|
|
|
|
C++11 compatibility is enforced by this unit test: `cutlass_test_unit_core_cpp11`.
