Yes. 16 processors in total got him to about 500k nodes a second. I do not know what Mhz Cray Blitz ran on. But probably Hyatt can enlighten us about it. However for matrix calculations and such that Cray was considerably faster than it was for Cray Blitz. Then you'll see the Cray didn't do that impressive for each Mhz whereas it was a lot more impressive for vector processing. Compare both Mhz of todays x86 with the Cray times 16 back then and the vector power versus todays x86 and you'll know what we are speaking about. Best regards, Vincent
