Unless your program is written to be multi-threaded it will only use 1 CPU at a time.

Does the CPU load remain always fixed for CPU0 till the process finishes, or have a look at process using top to see if the load shifts to CPU1 and back...

The other important thing is is the program compiled on this machine or someother machine. Because this can make a lot of difference on the performance of C programs if they are not compiled on same 64bit machine.
