Dear MXNet community, Due to multiple problems related to OpenMP and stale proposed change  we have been working on gathering performance data on the impact of using different OpenMP implementations with MXNet (great thanks to Stanislav Tsukrov for the hard work). The results can be found here .
As a short summary of the investigation: The difference between different compilers is insignificant. Native OpenMP implementations (more or less recent) perform equally (<5% difference). See more details in the document. Please review the document and share your thoughts on the topic. Thanks!
