(I was told that some follow-up items are still pending, but as the feature does work ...) Cf. also Andrew's talk of last year, https://linuxplumbersconf.org/event/7/contributions/749/attachments/560/988/AMD_GCN_Update_-_LPC_2020.pdf which I utilized when writing the attached wwwdocs patch.

AMD Radeon (GCN)

  • Debug experience with ROCGDB has been improved.
  • Support for the type __int128_t/integer(kind=16) was added.
  • +
  • When used as OpenACC device: the limitation of 1 worker per gang, 2 gangs + per CU has been lifted; now up to 16 workers per gang and 40 gangs per CU + are supported. (Except that the hardware limit of 40 workers total may + not be exceeded.)
