         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
 ---------------------------------------------------
Function Rate (MB/s) RMS time Min time Max time
Assignment: 600.0000 .0831 .0800 .0900
Scaling : 533.3333 .1002 .0900 .1100
Summing : 654.5455 .1161 .1100 .1200
SAXPYing : 654.5455 .1152 .1100 .1300
