Just an update... The Skylake bug hitting the press has generated a "mini-surge" of assignment requests in the DC Cat 4 range, and to a lesser degree in the LL Cat 4 range (as expected).

We're looking good, even in the LL Cat 4 range, but it's a good thing we refocused some of our firepower to be ready for the "big surge" expected when the new MP is announced!

Thanks for all the cycles everyone!

I'm curious about what the Cat ranges are. I see them talked about semi-frequently on the forums and I would really appreciate if someone could explain the concept to me.

I'm not sure if GPUto72 uses the same one as primenet, but the latter are here http://www.mersenne.org/thresholds/

I think GPU72 follows the same rules, since it is pulling assignments from PrimeNet.

Yes. In fact, it's a little more complicated than that...

GPU72 gets assignments from Primenet through a reservation spider, and then "loans" them out to GPGPU TF'ers and some (GPGPU or CPU) P-1'ers.

We carefully balance the available fire-power to ensure all the categories are appropriately "fed", trying to avoid any LL assignment being issued by Primenet not already TF'ed optimally nor not already P-1'ed. We're not always 100% successful, but we do our best.

Please note that this is why we're currently focusing about half our cycles on the "LL Cat 4" range, in preparation for the new Mersenne Prime announcement on Tuesday. We currently have a comfortable buffer for LL Cat 1 and 2, and are "just in time" for low Cat 3, but are a little tight for P-1.

I would be happy to work in that range for TF, if you feel the need. I have been taking WMS assignments for some time now. Just say, or change my internal GPU72 status, or whatever helps.

Thanks. So you (and everyone) knows, this happens automatically. The (rather primitive) AI assigns work as needed at the time of assignment, taking into consideration the heuristic latency of each user's assignment to completion temporal delta.

Those who choose "What Makes Sense" (WMS) or "Let GPU72 Decide" (LG72D) will be assigned what (range) is needed most. The difference between the two is that WMS honours the pledge level given (for example, only going to 72), while LG72D will set the pledge level needed (for example, 75).

All other options (for example, "Lowest TF Level", "Lowest Exponent", et al) honours the request and the pledge level.

Cool! It is good to know that I have been doing what is needed. I have kind of given up on factor chasing by getting lower bit level assignments. My understanding is that it is advantageous to let AMD GPU people have these.

Would you say P-1 is in need of assistance? I can move my Cat I DC box to P-1 temporarily if needed.

We're good.
