Detailed Description

Abstract threadpool interface.

The users are expected to subclass this interface and pass an object to the library during CPU stream creation or directly in case of BLAS functions.

Member Function Documentation

virtual void dnnl::threadpool_interop::threadpool_iface::parallel_for	(	int	n,
		const std::function< void(int, int)> &	fn
	)

pure virtual

Submits n instances of a closure for execution in parallel:

for (int i = 0; i < n; i++) fn(i, n);

constexpr uint64_t dnnl::threadpool_interop::threadpool_iface::ASYNCHRONOUS = 1

static

If set, parallel_for() returns immediately and oneDNN needs implement waiting for the submitted closures to finish execution on its own.
