Debug experience with ROCGDB has been improved.
Support for the type __int128_t
/integer(kind=16)
was added.
+ For offloading, the limitation of using only one wavefront per compute
+ unit (CU) has been lifted. Up to 40 workgroups per CU and 16 wavefronts
+ per workgroup are supported (up to a limit of 40 wavefronts in total,
+ per CU). Additionally, the number of used wavefronts and workgroups was
+ tuned for performance.
