HPVM-C Language
Host API
void __hpvm__init()
Used before all other HPVM calls to initialize the HPVM runtime.
void __hpvm__cleanup()
Used at the end of HPVM program to clean up all remaining runtime-created HPVM objects.
void llvm_hpvm_track_mem(void* ptr, size_t sz)
Insert memory starting at ptr of size sz in the memory tracker of HPVM runtime.
void llvm_hpvm_untrack_mem(void* ptr)
Stop tracking the memory object identified by ptr.
void llvm_hpvm_request_mem(void* ptr, size_t sz)
If the memory object identified by ptr is not in host memory, copy it to host memory.
void* __hpvm__launch(unsigned isStream, void* rootGraph, void* args)
Launches the execution of the dataflow graph with node function rootGraph. args is a pointer to a packed struct, containing one field per argument of the RootGraph function, consecutively. For non-streaming DFGs with a non empty result type, args must contain an additional field of the type RootGraph.returnTy, where the result of the graph will be returned. isStream chooses between a non streaming (0) or streaming (1) graph execution. Returns a handle to the executing graph.
void __hpvm__wait(void* G)
Waits for completion of execution of the dataflow graph with handle G.
void __hpvm__push(void* G, void* args)
Push set of input data items, args, (same as type included in launch) to streaming DFG with handle G.
