The language of choice was C# with Visual Studio 2013 for a 64-bit process. One idea was to try and use SSE to improve the throughput of the computation. Unfortunately the .NET framework currently (as of .NET 4.2) does not generate SSE instructions as part of its JIT compiler....

I had a situation like the following 1 2 3 4 5 6 7 8 private void DoSomeWork(CancellationToken token) { token.ThrowIfCancellationRequested(); // do lots of work } // some other code that might happen in a UI thread AsyncWorkScheduler.Schedule(()=> DoSomeWork(token)); I didn’t really have access to how the background task was scheduled, and to be honest I didn’t really care....
The task was simple. I have data on disk where the file sizes varied from 1kb to a couple of gigs. I needed to process the data and return the points from a method that returns an IEnumerable. The specific data file has a custom format, so I had to use a custom API to read the data. There was no async I/O option available unfortunately. Sounds simple enough. Here is my first version....
