Establishing a Performance Baseline

To set a performance baseline for the improvements that follow in this tutorial, compile your sources from the src directory with these compiler options:

ifort -real-size 64 -O1 matvec.f90 driver.f90 -o MatVector

Execute MatVector and record the execution time reported in the output. This is the baseline against which subsequent improvements will be measured.
