Simply porting an application shouldn't take much effort,
as long as vendor-specific libraries aren't involved.
However, special and sometimes intensive efforts are often
required to achieve good performance (high utilization).

The unfortunate fact is that funds are more easily spent
on hardware than on the human resources needed to utilize
them effectively.
