Speedup NEC-Engine, using multiple CPU-Cores

In standard use, only one NEC-Engine is running. The NEC-Engine does
not use multi-threading technique and therefore only one CPU-Core is
running.

Todays computers have multiple cores. Even I am using one with two
cores (Intel Dual-Core). And there are more cores available in the
future (3,4 and more).

My question is, is threre a solution for speeding up the antenna
calculation using NEC2/4-Engine? If not, I plan to code a wrapper NEC-
Engine, that is able to busy all CPU-Cores and merging the results to
one output file. Especially antenna calculation can be easly divided
into multiple parts (eg. radiation pattern division). If there is a
solution, I do not want to reinvent the tire again.

The nec engine would need to be multi-core aware. As some have already
pointed out, you would need the source and the ability to modify it ...

At the present time, I'd be surprised if a 64 bit version of the engine
even existed; however, I have not even looked into that.
