I just ran this. I used version 2.0 of streamd.f dated
9/30/91. I used n=3000000 and ntimes=10. I used version 03.01.0000.
0000 of xlf with compiler options "-c -O3 -qstrict -qsource -qlist
-qarch=pwrx". The output was:
--------------------------------------
Double precision appears to have 16 digits of accuracy
Assuming 8 bytes per DOUBLEPRECISION word
--------------------------------------
Timing calibration ; time = 69.0000000000000000 hundredths of a second
Increase the size of the arrays if this is <30 and your clock precision is =<1/100 second
