Subject: | Re: [Gems-users] Low IPC in Opal |
Dan, in order to discard memory as the cause of the low IPC I have configured the latencies to 1 cycle for hits or misses for all acceses. Still, the IPC continues extremely low. There are a few things in the code which I have changed to increase performance:
With these changes I get an IPC around 0.88 for FFT in 1 processor. Has anybody experiment with Opal an SPLASH-2? If this IPC something usual? Could anybody point me some others benchmarks to obtaing a higher IPC?. Maybe I am doing something wrong. Could anybody send me a correct configuration file for Opal and Ruby?. Thanks |
