Multiple GPU FLOPS tester Is there anyone with code

[herrbifi]

I am looking to test the glops or tflops we are getting out of multiple devices. I saw that N-Body and Fluid had built in flops tetsers but they only run on a single card. Is there any code out there to test multiple GPUs? We are running 4.

Thanks

If you want to measure the peak performance possible you just make a kernel that does a madd and a mul in the same statement lots of times re-using the values from previous lines.

If you want to measure the performance a useful algorithm gets, then the results of n-body and fluidsgl is also quite meaningless, it really depends on which algorithm you want to implement, as there can be big differences.
