Description

Hi,
I try to run the exercise 01 by my desktop, and the result is correct. However, I cannot get the timer and bandwidth. the results give

Total size S = 4194304 N = 4096 M = 1024
Computed result for 4096 x 1024 is 4194304.000000
Illegal instruction (core dumped)

I also try the given solution, same issue.

Start by reproducing Exercise 01 and the given solution on the reporter's desktop, recording the build and execution environment. Compare the successful computed result with the missing timer and bandwidth output and the illegal-instruction crash; done means both runs complete and report those measurements.
