group-collectives.hh File Reference

Overview

batchlas::portable:: group broadcast, shuffles and sums for any trivially copyable or complex T.

Under DPC++ these names are the sycl:: functions themselves (using-declarations), so a call compiles to exactly the direct sycl:: call. Under AdaptiveCpp they are wrappers: a value not 1, 2, 4 or 8 bytes wide moves word by word and a std::complex sum reduces its real and imaginary parts separately. A separate namespace keeps unqualified calls on sub-group partitions (sg_partition.hh) resolving as before.

Installed with the rest of include/batchlas (the install rule copies the tree wholesale); the device BLAS headers include it. Not a stable interface.
