Hello,I just wrote a parallel program using OpenCL,and ran it on my HD7990 card.When I tried to optimize my program , I read the GCN architecture whitepaper and saw this words:
"Double precision and 32-bit integer instructions run at a reduced rate within a SIMD. The GCN Architecture is flexible and double precision performance varies from 1/2 to 1/16 of single precision performance, increasing the latency accordingly. The double precision and 32-bit integer performance can be configured for a specific GCN implementation, based on the target application."
As my program is based on integer computing,so what and how can I do to configure my card or my program for integer computing?
