  • Store cl_device_id in c_dbcsr_acc_opencl_device_t and rely on it (instead of querying it repeatedly).
  • Make maximum size of work-group (WG) and preferred multiple available as part of device structure.
  • Discover subgroups. Avoid some compile-time decision (OpenCL 3.0).
  • Simplify handling WG-size (and SG-size).
  • Code cleanup (_DEBUG).
