This link is giving a 404 error. Is there an alternative repository?

Not sure if you found your answer in the meantime. Since it took some to find it when I started here's a reference for those reading only the last page of the thread:


The generation of the Notebook including access keys is integrated into GPU72 now.
https://www.gpu72.com/
You can create an account there and generate a notebook via the menu Notebook access Keys. Maybe a mod can put this info onto the first page of the thread?

I am getting about 30 min to 1 hour sessions of CPU only sessions using the GPU72 notebook. The problems that were happing before with the payload fetch have cleared. And I have been getting about 30 min to 1 hour of GPU in a single session once every 24 hours.

I use 5 google accounts and am able to run simultaneously12 notebooks on them (CPU only sessions, which always last 12 hours each) and every day I run a 10-hour long GPU session, normally T4s. I only run ECM on the CPUs and TF on GPUs
I am not using GPU72, though.

Yup. Fixed the profoundly stupid SPE wrt Colab P-1 assignments.

And, I also have been getting between 30 to 90 minutes of GPU access per account per day for the last couple of weeks. CPU-only is also regularly available, but they only last between 30 minutes to two hours.

Four of my thirteen accounts are being presented with a new message every time I launch an instance. Something along the lines of "Colab is for interactive usage. Are you still there?" with a "Cancel" button which must be clicked with a mouse (hitting return doesn't work).

Chris, can you upgrade your copy of mprime for the notebooks to the latest release? There have been some significant improvements that will speed P-1.

Default Continuing to be treated special LOL

I first got GPUOwl running on Colab on Sept 19, 2020.
About 10 days later I started a second instance.
I have been attempting to get 2 P100 instances per day since.
Almost every day I get 2 and they last an average of about 8 hours each; over 200 GhzDays.

In any case in these 165 days my Colab sessions GhzDays (29,300) have now surpassed my 4 core i5-3570K which started Oct 1, 2017; 1249 days ...yes almost a 3 year head start.

Default Trying to set up a second colab account

NEVER MIND ....
seems I needed to use an older version of libstdc*
I copied the versions from my existing working sessions and all is well now.

--------------------------

I have a second email address / google drive
So I created another colab/GPUOwl session

Once I remember to copy libstc* it worked just fine
.... until .... I tried to clone it to get a second session for that email address.

For the second session I copied gpuowl.exe and the libstdc* files from the first session
and ran it. I started getting this error.
Code:
./gpuowl.exe: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./gpuowl.exe)
I had this same error above until I got libstdc*

I tried all variations of deleting/recopying from the working version but no luck.

Weirdly though the log files in the second session kept showing the same contents as the first session even though they are in separate folder.
----------
So anyway I sent back to the "working" session just to be sure and it is no longer working ... getting the same error as above.

Advice?
Did I clobber something?

Does anyone know for sure what the Colab usage limits are tied to?

Email address running the session?
Email address of the Google MyDrive the software runs from?
IP address?
Other?

I have 2 email address; one is Gmail; one is other.

For the last 6 months I was running 2 colab sessions both connecting to the Gmail MyDrive but each logged on with one of the 2 email addresses above.

Today I created 2 new Colab sessions under a new MyDrive with the other email address.
When I went to run one it said my daily usage limits were exceeded.
Both are running from the same physical PC.

My 2 sessions from the previous email address had just completed.

I know some of you mentioned having 3 or more Colab sessions.

Not a clue.

Personally, I'm currently running fourteen (14#) Colab instances. Each tied to a separate Gmail account.

I'm getting about 30 minutes of GPU per account each day (sometimes more than an hour). CPU instances last for between 10 minutes and 10 hours, depending on when I ask for compute.

I have never been able to get more than a single instance to run using any of my various accounts. And although I haven't tried going past this, I have up to four (4#) different GMail accounts within each browser context (separate tabs; separate compute environments, most SOCKS tunneled).

As part of the SMS Attack research last week, I got a "burner SIM" to create Gmail and Fakebook accounts with. Interestingly, Google will no longer accept a cell number more than once to create an account (I feel a bit sorry for the next person who is assigned the number I used for three days...).
