The parallel computing lab that you are doing was created for the Unix environment that was used in our computer labs before the Fall of 2016 update. Linux offers all the same capabilities for parallel processing, but the commands to find some things out are different. Use these commands in answering the first four questions in the lab.
grep “physical id” /proc/cpuinfo | sort | uniq | wc –l
grep “^processor” /proc/cpuinfo | wc –l
grep “cpu cores” /proc/cpuinfo | uniq
The rest of the lab should work the same. If you have questions please ask your lab instructor for assistance.
