Stream

The Linux command to run these tests follow this format:

root@am62lxx-evm:~# stream -P <# of Cores/# of Threads> -N <# of Iterations>
For lower amount of cores being used, increase the number of iterations so there is enough time for measurements.

1-Core Stream

root@am62lxx-evm:~# stream -P 1 -N 500
2-Core Stream

root@am62lxx-evm:~# stream -P 2 -N 200
