Error compiling hello_world.cl with aoc

Hi JMilt1,

The theorized root cause there is that the Intel Quartus Prime software is using all the available processors, and the machine doesn't have enough memory to support use of all those processors.

Could you try to limit the number of processors being used by the Intel Quartus Prime software, for example to 2?

Thanks.

I tried limiting `aoc` to a single core using taskset. It worked in the sense that max CPU usage was 100%, rather than 600%, however, there seemed to be no difference in the memory usage - either way it used around 8.3GB before crashing with the same error "Error: Compiler Error, not able to generate hardware".
