+To define a new NVIDIA/CUDA plan class, add a new clause
+to '''app_plan_cuda()''' in sched/sched_customize.cpp.
+For example, the plan class '''cuda23''' is defined by:
+
+{{{
+    ...
+    if (!strcmp(plan_class, "cuda23")) {
+        if (!cuda_check(c, hu,

+To define a new ATI/CAL plan class, add a new clause
+to '''app_plan_ati()'''.
