6. 3 STEPS TO MORE SCIENCE TUTORIAL
Simple tutorial designed to help scientists to start with GPUs using
libraries and OpenACC directives.
 3 Tutorial Videos:
1. Step 1: Analyze: Use a profiler to identify hot
spots
2. Step 2: Parallelize: Expose Parallelism
3. Step 3: Optimize: Manage data movements
 Free PGI Community Edition

7. PAPERS
Acceleration of Element-by-Element Kernel in Unstructured Implicit
Low-order Finite-element Earthquake Simulation using OpenACC
on Pascal GPUs
 “OpenACC porting approach enables high
performance with relatively low
development costs. When comparing eight
K computer nodes and eight NVIDIA Pascal
P100 GPUs, we achieve 23.1 times speedup
for the element-by-element kernel, which
leads to 16.7 times speedup for the 3 x 3
block Jacobi preconditional conjugate
gradient finite-element solver.”
