We present a small C header for cross platform parallel
programming based the SDMP library which is now part of
Maple.  The header consists of macros and functions for
starting and stopping threads, finding the number cores,
measuring time, and locking outside of the OS scheduler.
In this programming model, a thread is created for each
cpu core, the data is divided manually, and the program
runs with minimal interruption.  Efficiency is achieved
using cache-conscious, non-blocking design.  We present
two examples: classical dense polynomial multiplication
and radix sort, and discuss how these algorithms can be
