[QUOTE=chalsall;412237]Having the deltas allow us to make an informed decision as to how many we can take to 75, and how many we should only take to 74. My goal is to not have assigned for LL'ing anything not at at least 75 bits above 65M. GPU72 will "recapture" anything released for P-1 at below 75 bits for final TF'ing, assuming a factor isn't found by the P-1 run of course.[/QUOTE]

I know this is going to show my ignorance of the setup, but when GPU72 reserves exponents to take up to 75 (in that range, for example), does it actually hold on to them until it reaches 75 then? So if someone gets that work and only takes it up to 74 bits but doesn't want to go to 75, that exponent will sit in the GPU72 reservations unless action is taken to unreserve it to feed the P-1 beasts?

I don't know if this would be a better or worse situation, but maybe GPU72 could reserve exponents to be done a bit level at a time instead of (optimistically?) taking a bunch and going all the way from like 72 to 75 in one go. Would it be better for this situation to take a wide range and first get them up to 73, then 74, then 75, sending them back to Primenet between each bit level being complete?

In a perfect world it wouldn't matter if a bunch of workers took a batch and went through them one exponent at a time, taking each one all the way to 75, then returning it. But given the circumstances, it seems like maybe the better option is to take at least the exponents in the leading P-1 edge and only do a single bit more at a time rather than going for the full 75 at once.

Again, it may be my total lack of comprehension on what's happening under the hood, so please disregard if I'm way off base. It wouldn't be the first time.

:smile:

Primenet currently hands out candidates for LL'ing based on the P-1'ed status first. P-1 done is assigned before no P-1 done, then the lowest candidates without P-1 done, grouped by the status %1M.

This is further complicated by the four different Categories for DC and LL.

It can be argued that GPU72 is actually "starving" Primenet such that only those candidates appropriately TF'ed / P-M'ed are available.

This could be the reason why my assignments are one bit higher on each side than what I have in the config file. I [U]do not[/U] have a problem with this at all. Just a curiosity .:smile:

I'm not clear what you're asking / stating?

Timestamp please ....

Can we get a Data_As_Of timestamp on this report.

Thanks

+1. :iws:
(albeit the update time is on the upper left corner of that page :razz:)

which is useless as not all the results reported to mersenne.org by that time is reflected in the update.

I don't really understand the feature request/bug report.

Because this report is so computationally expensive, it is only generated once an hour (at the top of the hour, as indicated in the top-left hand corner of every page). Yes, Wayne... You used to have access to the "real-time" report, but then you leaked the "secret" URL so I made it cached as well.

With regards to the report being out of sync with Primenet, that will (almost) *always* be the case. GPU72 only "spiders" Primenet twice an hour to get updates wrt factors found and P-1'ing/TF'ing completed.

Am I blind/short sighted/tunnel vision? :blush:
Or was that added recently?

In any case .... cool!

My bad...sorry.

But that explains why it refreshes so fast now.

Been there for as long as GPU72 has existed. (Not meaning to be mean or anything, but I believe it was actually you who asked it be rendered as UTC rather than AST many years ago...)

All times are UTC. The time now is 18:10.
