[QUOTE=Batalov;235816]The PRP estimated times are about a half of what it really takes; for example, try:
[FONT=Arial Narrow]PRP=2,10,249448,1,0,0,"3"[/FONT][/QUOTE]

Bug in the code. Estimate is off by log2(10).

Right, sound about right.
I re-observed the running times and they are about 9-10minutes (the next FFT size kicked in), so 1:0.3 is right.

Past ECM credit has been bumped about 20%.[/QUOTE]

Do you plan to also adjust the code that estimates the completion times? For me it is still out by about a factor of 2. I am completing the assignments in 11.5 hours but the estimate is 5.5 hours

Closer here

Under 26.3b3 (64-bit) the estimates for ECM work in the 5.4M range are about 3:05 apart in my assignments. Actual time is ~ 4:00. That's closer than I used to see at least.

The GHz-day credits now match roughly what I see from LL or TF work (~ 4.25 GHz-days per 3.8GHz i7 core), so that change was well done.

ECM oddity? Saving the clutter of a new thread.
 

Just for fun I decided to complete the ECM of 355717; the lowest exponent that was not "DONE" ECM at B1=50,000, B2=5,000,000.

I ran 114 curves (took my PIV only 18 hours). :boxer:
Sorry, no factor found. :sad:

I checked the ECM Progress page about an hour after the test finished and sure enough it shows "DONE" in the first column

BUT it also shows 56 curves in column 2 though no such activity shows up in the Exponent Status report. :confused:

This is normal (and confusing). The column header shows the number of curves that need to be run at that B1 level [I]if you are starting from scratch[/I]. However, we aren't starting from scratch. We've already run 300ish curves at B1=50000, which is equivalent to having run 56 curves at B1=250000.

I took the remaining exponents in the 35x,xxx range and completed the first level of ECM for them (B1/B1=50,000/5,000,000)

In most cases I took the count from about 180 to 280.
80 exponents
~7,700 curves in total
4 factors found.

Roughly how many GHz-days, and how long did it take you?

[QUOTE=KingKurly;251267]Roughly how many GHz-days, and how long did it take you?[/QUOTE]

80.6 Ghz days total (0.5239 for each 50 curves)
PIV 2.8 GHZ completed 50 curves in just under 10 hours
PIV 3.4 GHZ completed 50 curves in just under 8 hours
