This is a micro-benchmark for HSA platform.

This sample is modified from the original CLOC sample code. Please make sure you have set up the HSA environment before using this sample.

#Execute

1. Run run.sh in dir.

#Problem

• There are still some problem needed to be fixed.

1. Why global_ld & const_ld cannot execute successfully.(Both ISA are the same)
2. Why speed of memeory bandwidth global,local,private,const doesn't make sense.(HSA runtime dosn't support private segment yet)

#Result

• See the picture in dir.

1. HSA_enqueue
   no_branch for empty kernel.
   vector_copy for simple kernel just like vector_copy.(To ensure result is accurate)
   
2. SNACK_enqueue
   no_branch and vector_copy are the same function with HSA_enqueue.
   
3. Memory_bandwidth
   const and global_ld are not make sense.
   Private segment is not support in HSA runtime yet.
   
4. branch
   Here is micro-bench for branch penalty.
   Penalty is almost linear.
   
5. reduce
   We use a simple exaple find max to test reduce.
