Detailed Description

A wrapper around technology specific streams.

Streams are used to enable and order concurrent operations on accelerator devices. The default stream used in hamr is a stream-per-thread where available. However, note that libraries built seperately will likely use the default blocking stream and if so explicit specification of the stream when calling into those libraries is necessary. Note that hamr passes stream correctly when interfacing with Python. In most cases the hamr API's requiring a ::stream can be passed the technology specific stream due to implicit conversion operators implemented here.

Member Function Documentation

◆ get_stream() [1/2]

size_t hamr::stream::get_stream ( )

convert the technology specific stream to an integer

◆ get_stream() [2/2]

size_t hamr::stream::get_stream ( )

convert the technology specific stream to an integer

◆ operator bool() [1/2]

hamr::stream::operator bool ( ) const

evaluates true if a stream has been set

◆ operator bool() [2/2]

hamr::stream::operator bool ( ) const

evaluates true if a stream has been set

◆ print() [1/2]

void hamr::stream::print ( ) const

sends the value of the stream to std::cerr

◆ print() [2/2]
