Hi ,
Thanks for reaching out . We may need more details to take a look at this in house . Can you please follow How to report a bug to report us a bug ticket which will sync and keep a communication channel with you and interact with our engineering team .
In the bug report , we want to know details following and please kindly include them as possible as you can
- What is the result data unit , milliseconds ?
- What is ‘128 FFTs’ , do you mean 2D or 3D ?
- What is the used data decomposition
- Is your comparison “standard FFTW” from a single node ?
- Most important , we may want a self-contained reproducer to check it practically in house
Attachment can be added to NVSDKIssues@nvidia.com
Best,
Yuki
