A fair trade for the compute. P.S. I *really* wish Colab Pro was available here in little Bimshire. Google, I'm willing to pay!
ditto :)

At least one account has not gotten a gpu since 2022-01-16 despite multiple sessions per day launched, leaving incomplete a TF assignment 82% done needing 14.5 more hours of T4 gpu time. K80 is faster DP (PRP, LLDC or P-1), T4 ~4x faster SP (TF).

This happens to me regularly. Colab will randomly decide that one of my accounts can't get a GPU, and then 1-3 weeks later, it suddenly can again.

 2022-01-25, 22:16 #290 mrk74   Jan 2020 2·29 Posts Not getting credit for TF's First let me say I'm not worried about not getting credit. I'm doing it for the cause but I am wondering what's going on. To explain: I had my last TF in May. My ID was attached to it. I started getting them again in December. I just happened to look all the ones since December have been marked Anon. I haven't changed anything as far as I can remember so I don't know why the change would have happened. As far as I can tell my ID IS attached to P-1's.

In order for the "Auto Colab Submission" spider to work, a "slaved" mprime is used to create, and then keep up to date, the "virtual machine" called GPU72_TF for each account.

Unfortunately, Primenet sometimes comes back with a set of messages which cause the VM to be moved to ANONYMOUS. In your particular case, I didn't notice this, and so lately your results have been submitted thusly.

I have corrected this, so moving forward things should be "sane". Also, you did receive all of the credits as appropriate on GPU72, but not on Primenet. There was a unique CID for each submission, so I guess George, Aaron, and/or James could fix the historical data, but what I'm hearing is you don't really care all that much about credits.

Again, my apologies for the SPE. And thanks for bringing this forward. I will keep an eye out for this kind of thing more closely moving forward.

No problem. More wanted to let somebody know in case the credit was a big deal to them. Honestly I don't look too often at but I decided to on one and that's how I noticed it.

Hmmm... Weird. Thanks for pointing this out. Sorry for any wasted cycles.

 2022-03-14, 21:09 #295 LOBES   Mar 2019 USA 5×17 Posts I started up a Colab session to test out the updated P-1 code. Only got through Stage 1 @ 38.78% before it stopped on me. Anyway, I just "moved" the assignment over to my home PC and finished it off since I didn't want it hanging out there. Over a week later its still assigned to me as a Colab assignment. 110479219 I'm hoping that will eventually clear itself out? From past experience, if I were to start a new Colab session, I would get a new P-1 assignment anyway, so I am not aware of any way to actually finish that assignment off using Colab.

There is an old and wise saying... No good deed goes unpunished.

You present an "edge-case"; serious programmers welcome these.

In this particular case, a race condition between what was assumed to be automated and what was eventually completed under the direct direction of a human.

It's all cool. Actually... beyond that... Thank you sincerely for demonstrating just how fragile some code paths can be!
