CMPS 297S/396AA: GPU COMPUTING
ASSIGNMENT 6
In this assignment, you will implement an exclusive scan kernel using the Brent-Kung method.
Instructions
1. Place the files provided with this assignment in a single directory. The files are:
 main.cu: contains setup and sequential code
 kernel.cu: where you will implement your code (you should only modify this file)
 common.h: for shared declarations across main.cu and kernel.cu
 timer.h: to assist with timing
 Makefile: used for compilation
2. Edit kernel.cu where TODO is indicated to implement the scan and add kernels. Please take
note of the following:
 You must implement the Brent-Kung exclusive scan. No credit will be given for
implementing Kogge-Stone, or inclusive Brent-Kung with shifted inputs.
 Your kernel is expected to work for any set of input dimensions so make sure to handle
boundary conditions correctly.
 Your code should be optimized by using shared memory and re-indexing threads to
minimize control divergence.
 You do not need to apply thread coarsening.
3. Compile your code by running: make
4. Test your code by running: ./scan
 If you are using the HPC cluster, do not forget to use the submission system. Do not run
on the head node!
 For testing on different input sizes, you can provide your own values for input size as
follows: ./scan <N>
Submission
Submit your modified kernel.cu file via Moodle by the due date. Do not submit any other files or
compressed folders.
