Ivy bridge ep gflops for bitcoin

Stack Overflow works best with JavaScript enabled. I understand now why I was confused. If, for example, you want to add a very long list of f. Intel Core 2 and Nehalem:

By posting your answer, you agree to the privacy policy and terms of service. The numbers would be exactly double the DP numbers. I understand now why I was confused. I'll have to get back to this.

You don't need to manually break the loop, a little bit of compiler unrolling and out-of-order HW assuming you don't have dependencies can let you reach a considerable throughput bottleneck. Floating point addition, multiplication and FMA all have a throughput of 2 instructions per clock cycle and a latency of 4. Stack Overflow works best with JavaScript enabled. You need to double the numbers since the counter is assuming DP. Unrolling ivy bridge ep gflops for bitcoin times with FMA gives me the best result.

For Nvidia Fermi I read en. Sign up using Email and Password. I'm confused on how many flops per cycle per core can be done with Sandy-Bridge and Haswell.

Now it works and I get twice like you said. Floating point addition, multiplication and FMA all have a throughput of 2 instructions per clock cycle and a latency of 4.

Here are FLOPs counts for a number of recent processor microarchitectures and explanation how to achieve them:. Stack Overflow works best with JavaScript enabled. See my answer at stackoverflow.

Unrolling 10 times with FMA gives me the best result. In my experience, the places where one does a lot of add are bandwidth-bound such that more add throughput won't help. Helping Teams Get Started. Most HPC codes that are compute-bound i.

Add to that hyperthreading and 2 operations per clock become quite necessary. Floating point addition, multiplication and FMA all have a throughput of 2 instructions per clock cycle and a latency of 4. See my answer ivy bridge ep gflops for bitcoin stackoverflow. In response to your edit: If your code contains mainly additions then you have to replace the additions by FMA instructions with a multiplier of 1.
