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

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.

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.

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.

Thanks, I have just released one that he has completed
