Very Strange
 

[B]For James Heinrich
[/B]
Late yesterday evening, after your data regeneration, my batch file executed the following:

[CODE]C:\Wget\wget.exe "https://www.mersenne.ca/tf1G.php?download_worktodo=1&tf_min=68&tf_limit=69&min_exponent=3700000000&max_exponent=3709999999&max_assignments=100&biggest=0" -O - > worktodo.txt
[/CODE]Instead of retrieving 100 assignments, like it says, it pulled in over 61,000. This was on my HP. I compared this line with what I have on my i7. No difference.

I have no idea what happened. [U]These will be completed[/U]. It might take a day, or so.

:confused:

Haha, I think James got pissed off by me requested one thousand assignments every 7 minutes, and he decided to give sixty times more or so, because I also got like 60k of them and now I am calling base every 7 hours instead, since last night...

Already PM'd James about it earlier, before realizing what probably causes it. There's a new way of requesting "GHz-days of work" instead of number of assignments. But unfortunately that number of assignments doesn't seem to work now, instead it gives out the default (1000) GHz-days of work, or at least that's what I got on three separate occasions already. Two of them aren't a problem, they were on machines that are fast enough, but the third one happened on a Jetson Nano that can do about 25 GHz-days per day. :yawn: I'll have to rearrange things a bit...

[QUOTE=nomead;530461]But unfortunately that number of assignments doesn't seem to work now, instead it gives out the default (1000) GHz-days of work[/QUOTE]You correctly diagnosed my typo :redface:

The new [i]max_ghd[/i] parameter overrides [i]max_assignments[/i] if present, but I made a small typo that ended up making it hardcoded to 1000 GHz-days, hence your unexpected large number of assignments.

It should be fixed now, please let me know if you still have problems (once you get through your longer-than-usual assignments).

@Laurv: You can request as many assignments as you want as often as you want, it doesn't bother me in the slightest. :smile:

I split this between two computers. I periodically stop everything and do a manual submission. There is nothing on James' submission page about a size limit (bytes). For reference, [I]PrimeNet[/I] is 2MB.

[QUOTE=storm5510;530470]There is nothing on James' submission page about a size limit (bytes).[/QUOTE]There is no hardcoded limit, but there seems to be a server timeout (45s I believe) which I can't figure out how to bypass which practically limits the submissions to somewhere in the vicinity of 300k-400k lines. As a guideline, limit your results submission to 200k results at a time or fewer to ensure they all get processed. Not that this is a major issue anymore, since all the easy pickings have been done.

[QUOTE=James Heinrich;530474]...As a guideline, limit your results submission to 200k results at a time or fewer to ensure they all get processed...[/QUOTE]

Doing a bit of averaging, 200,000 results would make a 22MB data file, more or less. This includes the user information in each line. I believe we are all [U]really[/U] safe here. :smile:

Kudos to James
 

Hey, I just wanted to publicly thank James Heinrich for a change he made quickly today.
Couldn't find a better place, so it's going here.

Take a look at the output of his P-1 bounds/odds page;
pick your application, prime95/mprime, gpuowl, or cudapm1, and worktodo format or command line. Also very nicely formatted. Load the following to see what I mean.

[URL]https://www.mersenne.ca/prob.php?exponent=333001043&b1=3360000&b2=84000000&guess_saved_tests=2&factorbits=81&K=1&C=-1[/URL]

Noting, however, that there's currently a (significant) disagreement between my calculus and what Prime95 (the program) selects as bounds. Presumably this is an error on my part, but I'm waiting to hear back from George on his take on the discrepancy. It may be related to the switch from LL to PRP.

[I]I assume it is safe to restart my batch process and not get 60,000 exponents[/I]?

[U]Off-topic, but related[/U].:I did not know George had increased the maximum exponent by nearly one-billion for [I]Prime95[/I]. This means I can run some of these on my laptop which has no GPU. For what it is, it is not doing bad at all with 1010's.

[U]On-topic[/U]: The manual assignment page seems to have a bit of an issue. It says you can select the number of exponents you want [U]or[/U] specify it in gigahertz-days. It refused to do the "or" function for me. It insisted on both, but used the gigahertz-days part to do the assignment. I requested 10 assignments for my laptop and then put 10 in GHz days. I got 170 assignments. I did not know what I would get using GHz days Running this many is not a problem.

[QUOTE=storm5510;530554]I assume it is safe to restart my batch process and not get 60,000 exponents?[/QUOTE]Yes, the [i]max_assignments[/i] parameter will be respected again.

[QUOTE=storm5510;530554]It says you can select the number of exponents you want [U]or[/U] specify it in gigahertz-days. It refused to do the "or" function for me[/quote]It's behaving as intended: if you specify GHz-days it will give you that many GHz-days, if you leave that blank it will give you the requested number of assignments. I've added a little javascript trickery to make it more clear for the human-facing HTML form, but be aware that if you're requesting assignments via GET then you need to specify only one of ([i]max_assignments[/i] | [i]max_ghd[/i]), the latter will override the former if both are present.

[QUOTE=storm5510;530554]I did not know George had increased the maximum exponent by nearly one-billion for [I]Prime95[/I][/QUOTE]I don't think this is anything new, as far as I know Prime95 has always supported exponents up to 2-billion (note: not 2[sup]31[/sup]). I fired up a copy of v24.13 from 2005 and it supported such exponents.
