I get 2 free P-100 almost every day each for about 8 hours.

Do you guys do LL/PRP? (as I am only doing TF on colab, I don't get it what's the big fuss about P100, for me the best hit is T4, but that's rare and only survives 2-3 hours, the most of the time I get "no GPU")

I am doing GPUOwl P-1 under Colab.....P-100 are 4-8 times faster than any other GPU for this.
When I was doing TF a few months ago I too was getting 2-3 hours a day and almost never got a T4. I'm not sure why I get 3 times as much time using these same GPUs for P-1.

And around 7h25min today (interestingly it was not an integer multiple of 30 min + a few minutes as usual). More and more close to @petrw1's 8 hours.

How many NBs are you running concurrently?

Now it has caught me too, the first time that I no longer get a GPU runtime on all 3 accounts.

Works for me again, also with P100, but the running times are now a little shorter about 7-8 hours

Yes. All GIMPS computation types are possible there on either cpu or gpu. But, latency can be a problem. Expiration can be a problem for wavefront primality first tests or higher. And CUDAPm1 did not seem to work. https://www.mersenneforum.org/showthread.php?t=24839
Occasionally an installation stops working for some reason, such as it no longer matches cudart, driver, and build versions, and then begins working again days later.
I just had cpu-only sessions of 12:11, 12:07, 12:03 on 3 simultaneous instances from one system, and 12:05 and 3:22 from another. In the next round, 3 of the 5 got gpus just now.

MIKR seems to being allocated the same exponents as myself.
Is this a glitch in the system?
Code:
M29301253 from 2^70 to 2^71
M29301277 from 2^70 to 2^71

He's not using GPU72. He stole several of mine too. If you have anymore you might as well release them. He's now in 28.0 so won't be bothering us.
