|
||||
*
|
||||
* GPUs perform networking operations on a context that is created by the
|
||||
* application programmer or a "default context" managed by the runtime.
|
||||
*
|
||||
* Contexts can be allocated in shared memory, in which case they are private
|
||||
* to the creating workgroup, or they can be allocated in global memory, in
|
||||
* which case they are shareable across workgroups.
|
||||
*
|
||||
* This is an 'abstract' class, as much as there is such a thing on a GPU.
|
||||
* It uses 'type' to dispatch to a derived class for most of the interesting
|
||||
* behavior.

/*

* Dispatch functions to get runtime polymorphism without 'virtual' or
|
||||
* function pointers. Each one of these guys will use 'type' to
|
||||
* static_cast themselves and dispatch to the appropriate derived class.
|
||||
* It's basically doing part of what the 'virtual' keyword does, so when
|
||||
* we get that working in ROCm it will be super easy to adapt to it by
|
||||
* just removing the dispatch implementations.
|
||||
*
|
