trigonometry

I need to call Atan on millions of values per second. Is there a good library to perform this operation in batch very fast. For example, a library that streams the low level logic using something like SSE?

I know that there is support for this in OpenCL, but I would prefer to do this operation on the CPU. The target machine might not support OpenCL.

I also looked into using OpenCV, but it's accuracy for Atan angles is only ~0.3 degrees. I need accurate results.

Create NSC-File for multicast streaming with Windows Media Streaming

as seen on Server Fault - Search for 'Server Fault'
For streaming multicast I need to create a NSC-file for the players - this file is pseudo-coded by Microsoft. Now I need to create this file for each proxy-publishingpoint. Is there any way to stream multicast without the NSC-file or can I create the NSC-file on another way? Thanks for any idea ;) >>> More
