Mersenne: Error: Illegal Sumout

1998-10-28 Thread Chuck Baker

I think my Prime95 broke!  I am on iteneration 479162/5518463 and get a
continuous stream of "ERROR: ILLEGAL SUMOUT" messages which are constantly
sent to the primenet server.  I am running version 16.3.1 of Prime95.  I
have no choice but to shut it down until I figure out what went wrong.  Any
suggestions?

Thanks,

To the exact cent?  I guess you have not heard the news that the Euro dollar
is causing.  The calculations must be correct to the 10th of a mil for the
conversion factors.  Thus one needs E,EEE,EEE,EEE,EEE.c (yes, 5 decimals
to round up.)  It is known in Europe as maybe worse than the Y2K issue.  In
Italy, they don't have decimals at all for the Lira so adding any decimals
at all is a headache.

P.S.  All these side notes being passed around are very interesting, even if
off the topic somewhat.

Another area that will inevitably demand such data types is the financial

calculations that CPAs demand) and you want to represent anything under 
$100 trillion to the exact cent, you already need 64 bits for the 
significant digits, which means the sign nibble pushes you over the 
64-bit limit.  Budgets (especially national ones) are only going to get 
bigger and things like the Euro and conversions between currencies will 
make it necessary for the international financial types to go to such 
data sizes.

This is probably an interaction with some new piece of software.
I know that the OS should protect you from such interactions, but
this problem is quite common.

Have you installed any new device drivers lately - especially those
that might use MMX (audio and midi cards)?  Are you running any new
programs?

The good news is that these errors do not seem to affect prime95's
accuracy (unlike other error messages).  A recent double-check had
3 SUMOUT errors, but the residues matched anyway.

Hope that helps,
George

It happened to me.  Turned out to be bad tag RAM.

Mersenne: Bannerz

1998-10-28 Thread STL137

I've resumed work on my GIMPS banners again. If you have any suggestions as
how to improve the current banners that I have, or as for new banner ideas,
please E-mail me personally. Thanks! The gallery I have can be found at:
http://members.aol.com/stl137/bannerz/gallery.html
I have fixed numbers 4, 7, 9, and 17 to have more contrast. Number 12 now says
5300+ users. And I have 8 or so new banners cooking now. I'll upload all this
when the new banners are done.
Yah!
