HASH.HELP has never guaranteed a prime number. You'll note their wording - it's not a recommended modulo, it's the smallest you should make it.
I was told by the uniVerse folks (back when it was Vmark, so that tells you how long ago it was) that since not all of the hashing algorithms required prime numbers to be efficient, HASH.HELP wouldn't always recommend a minimum modulo that was prime. Why it would recommend two different types, I don't know. The only thing I can think of is that they're running two different types of analysis - one just a general overview and one a more detailed run. That's just a guess, though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jerry Banker Sent: Wednesday, June 20, 2007 8:58 AM To: u2-users@listserver.u2ug.org Subject: I just came across what may be a bug in HASH.HELP. I ran HASH.HELP on a static hash file and it told me the smallest modulus should be 80015 (yes, not a prime number), smallest separation or 4, and the best type of 10. I then ran HASH.HELP.DETAIL on the same file and got 80021, 4, and 18 respectively. In this second case the modulus is a prime number. No changes were being made on the system because it is our test system and I was the only one on it at the time. This was on Solaris 8 running Universe 10.1.12 in Reality flavor. ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material not intended for Public use.
