Build

The mapper requires the following additional prerequisites:

• LLVM 11.0
• CMAKE 3.1

Execution

Generate DFG for a target kernel:

 % opt -load ~/this repo/build/mapper/libmapperPass.so -mapperPass ~/target benchmark/target_kernel.bc

Initial Evaluation

Different types of nodes in each DFG:
