astonishing facts about aocl compiler : vector_add -> No DSP used, y[i]=x[i] comp er

1) Only a tiny percentage of the chip is being used here. And the percentages shown are integer-ized, so you may need to use a dozen DSPs to change the 0% to 1%. But if you want to scale up the size and performance try vectorizing or num compute units.

2) The aoc compiler uses Quartus under the hood, Quartus needs a lot of memory, 64GB is a good size. The error message you're getting (below) is definitely pointing to a system with too little memory.

Error (114016): Out of memory in module quartus_syn (1688 megabytes used)
