gpu floating point precision benchmark tool to verify accuracy of floating point calculations


 Is there any benchmark tool available to verify the accuracy of floating point precision calculations on GPU with comparison to CPU.


If the goal here is to compare specific floating-point computations between CPU and GPU, I would recommend reading the following whitepaper that explains in some detail why differences may be observed:

Since floating-point computations on both CPUs and GPUs have a certain amount of numerical error associated with them, I prefer and recommend comparison with a higher precision reference (such as double-double arithmetic) to assess the error for each. What error in the final results is acceptable is typically a function of the application.

Thanks for a quick reply
