Double check assignments
 

This morning I was able to bring up a GPU72 Trial Factoring Colabratory Notebook with an access key using a work type of "GPU72 decides." I noticed a little while ago looking at my View Assignments that I have been doing DC TF in the 102M range (.eg 102432997). It seems a little odd to be doing DC in this range. If it is truly DC work, why is it important seeing that the DC wavefront is decades from here?

Colab "Let GPU72 Decide" is temporarily doing high DCTF which are at very low TF levels. This is just a bit of "clean-up".

If you would prefer to do LLTF, change your Notebook Instance's work-type.

Just so everyone knows, Colab LG72D is back to doing "breadth-first" LLTF work.

[QUOTE=kladner;535196]It's doing pretty well now at DC, but is there a current need for P-1?[/QUOTE]

Actually... There is perhaps a need for some "quality" P-1'ing...

Cats 0 and 1 are more than fine, but Cat 2 might be worth "chasing" with P-1'ing. For this reason GPU72 is now only offering P-1'ing at "high" levels, in order to have a least a few ready for Cat 2 workers as they climb into the 10xMs.

So, anyone who might enjoy doing some near-term needed P-1'ing, please consider doing some through GPU72. On the other hand, those who simply want to process as many P-1s as possible per "wall-clock" time, consider getting the P-1 work directly from Primenet.

Or, perhaps, I should offer a new P-1'ing worktype?

Thoughts?

You already have this....don't you?

Would the desirable assignments come in through the proxy with P95 set to P-1? No assignments available through GPU72 manual page...

It would be cool if you got them through the proxy (for tracking purposes), but...

They're also available from the manual assignment form. You just pointed out an SPE error in my preview code; it was constrained by a <99,000,000 clause...

Man, who would have thunk it? :smile: :tu:

Ah, good point... When I have some cycles I'll bring in some candidates to P-1 in the high 100M range, in prep for Cat 2 entering there (~2 months or so). Then the options (Lowest, Highest) will make sense again.

So, a quick update (I'll have some cycles over the weekend to do a more indepth report on where we are).

Right now, we are under a bit of a crunch in 106M (Cat 4).

Ben's throughput has stabilized a bit, so [URL="https://www.mersenne.org/primenet/graphs.php"]Primenet's net LL throughput is averaging about 680 LL's a day[/URL] (down from ~900 a day).

Because of this, the [URL="https://www.mersenne.org/thresholds/"]assignment ranges ("Cats")[/URL] have actually been dropping for Cats 1 through 3. Because I didn't foresee this, we've had to release some candidates at 76 and 75 "bits" in 106M.

Because of the recent availability of Colab again, it would be good if people choose "LL Depth First" for at least a few of their [URL="https://www.gpu72.com/account/instances/"]Instances[/URL]. This will assign work to 77 bits in the high 106M range.

Please know that each 76 to 77 run takes approximately 2 hours on a full T4. But this helps the P-1'ing job done on the CPU before the LL test (in addition, of course, to eliminating candidates).

But, as always, it's your time (the compute is free). WMS or Breadth First is helpful too!

Man, what a problem to have!!! :wink:

Happy to go through the proxy. Just checking that would get the desired results. :smile:

Always a good idea to check. SPEs abound with things moving so quickly... Oh, and I just noticed that your machine grabbed a batch through the proxy. Sweet!

Just so everyone knows, I've also brought in 200 candidates to P-1 in the high 100M range. For anyone willing to work up there, they're available from the manual assignment page by choosing "Highest Exponent" under the "Options" field.
