the classic 79,3 limit
 

What is the classic 79.3 limit in [url]www.mersenne.org/report_milestones?[/url]

For many years, 79.3million was the limit that Prime95 could test.
The milestone and status page was [URL="https://www.mersenne.org/report_classic/"]this[/URL] with the milestones below. As each level associate with an FFT size was completed (DC'ed), it was collapsed into the top row.

HTH

Why does the GIMPS milestones page indicate
[QUOTE]Countdown to verifying all tests below the classic 79.3 million limit: 19[/QUOTE]
but when you click on the number only one active test is displayed?

Never mind, I just read the posting in the newer milestone thread.

New features in Version 24.12 of prime95.exe ~2009
2) As a side "benefit" even larger FFT sizes are now supported. This allows
testing of exponents up to 596 million. Not recommended.


New features in Version 19.0 of prime95.exe ~1999
2) New FFT lengths. The program can now test exponents as large as
79.3 million. Also, smaller FFT lengths are supported for use in
ECM and P-1 factoring.


New features in Version 16.1 of prime95.exe ~1999
1) Prime95 can now test exponents up to 20.5 million.


New features in Version 12 of prime95.exe ~1997
3) The program can now test exponents as high as 2,630,000!


I remember at the times, thinking it would be a long time before it would need increasing from 20M or 79.3M; then the 596M capable release came along and we're set for life.

I just took a look at the page: only 13 "Status unknown", corresponding to an effort of 470 P90 CPU-Years. I remember, some 15 years ago or so, the latter figure being well over 27 million!... We came a long way, no doubt. :showoff:

No more unknowns!...

"Only" 596,735 DCs to go, as of now.

I wonder when can we expect this amount will go down to <10,000 ?
