80M to 64 bits ... but not really reserved

I'll be done in 2 and a half days.
Nothing left unassigned below 100M now.

On another note, if all goes well and I get my new quad build this week I may be cease and desist these special low bit ranges though I still have a Duron that is best suited for this work but it is not very accessible so unless things change...

Thanks, it's been fun.
Watch for me though in other work types.

Quad got built sooner than I expected so the PIII was retired early. I moved the remaining 31 83M assignments to a PIV ... will be done within 14 hours.

83M done to 64 bits.

"you" in this context can be any that have been collectively working in this <100M range.

I still have two venerable Athlon XPs that are still going well, mostly. I'm trying the slower in the 209M range from 2^61 to 2^64. With the faster one I've gone the other way, down in 4.9M, from 2^61 to 2^62, coordinating with an old P4 to make sure they all have enough P-1 first. I like finding factors for small exponents - not that I'm expecting to find many! As a bonus the credit/time is better below 2^62: Athlons are weak at LL (no SSE2), brilliant for TF below 2^64 and extra brilliant below 2^62. The benchmarks below are for Prime95 25.9 on an Athlon XP at 2088MHz, leaving out the embarrassing LL numbers to save pixels.

Of course, at their age either of these could kick the bit bucket at any time.

Best time for 58 bit trial factors: 5.989 ms.
Best time for 59 bit trial factors: 5.989 ms.
Best time for 60 bit trial factors: 5.994 ms.
Best time for 61 bit trial factors: 5.990 ms.
Best time for 62 bit trial factors: 6.002 ms.
Best time for 63 bit trial factors: 10.392 ms.
Best time for 64 bit trial factors: 10.388 ms.
Best time for 65 bit trial factors: 25.916 ms.
Best time for 66 bit trial factors: 26.377 ms.
Best time for 67 bit trial factors: 26.844 ms.

It seems it would be beneficial for prime95 to have an options:
TF to 62-bits
TF to 64-bits
TF above 64 bits

Or just allow specifying minimum & maximum range for TF
Or maximum & minimum range for P1

Otherwise we just need to do manual assignments to get the ideal assignemts - but even so Low TF goes to 64 bits...

I put in a post about a week ago in the LMH forum asking if those with big hardware could consider leaving the <64 Bit assignments for our slow PC's.

But too late asking for a TF<62 option. The last few hundred will be gone in the next few hours.

[petrw1]

All exponents <62 bits assigned or complete (except a few very LOW ones).

Just over 20,000 assigned but not yet complete.
9,000 in the 200M range
11,000 in the 700M range.
