Angelos found an interesting article via the UK MSDN Flash. If you did as well, check out more about that on the author's blog (one more reason to be sorry PDC was cancelled).
Anyway...
In a not so unrelated area, on a list that I am a member of, a question came up about affinitising a managed thread to a specific CPU. Jeffrey Richter came to the rescue by pointing out the
The code (and much more) is part the Power Threading Library which is available on the Wintellect site.

In a not so unrelated area, on a list that I am a member of, a question came up about affinitising a managed thread to a specific CPU. Jeffrey Richter came to the rescue by pointing out the
System.Diagnostics.ProcessThread and its ProcessorAffinity property but then the harder question came along of how to associate that class with the System.Threading.Thread class. Below is the answer in C# from Mr Richter again: // Call this passing in 0...where
public static ProcessThread GetProcessThreadFromWin32ThreadId(Int32 threadId) {
if (threadId == 0) threadId = ThreadUtility.GetCurrentWin32ThreadId();
foreach (Process process in Process.GetProcesses()) {
foreach (ProcessThread processThread in process.Threads) {
if (processThread.Id == threadId) return processThread;
}
}
throw new InvalidOperationException("No thread matching specified thread Id was found.");
}
ThreadUtility is a class containing at least: [DllImport("Kernel32", EntryPoint = "GetCurrentThreadId", ExactSpelling = true)]
public static extern Int32 GetCurrentWin32ThreadId();The code (and much more) is part the Power Threading Library which is available on the Wintellect site.
