I read over at mersenneforum.org that people with a Google account have access to free GPUs (Tesla K80) at https://colab.research.google.com/. People at mersenneforum.org wrote a python script that can run the trial factoring programm mfactc for Mersenne numbers, so I wondered if Colab can also be used for PG apps. I tweaked the script a bit and was able to run the GFN sieve program and Genefer (standalone).
It works like this: You upload the program you want to run to your Google Drive in a folder, then run the program from a python script in Colab (which you give permission to access your Drive files). The results get saved in your Google Drive.

Quick Tutorial for MSR:
1. Have a folder called "gfn_sieve" in your Google Drive with "gfnsvocl_linux_x86_64" in it.
2. Get this python script and add it to Colab: https://colab.research.google.com/drive/1RC_-Rjpxw4SFAFuXImQMRNm6UlYpHuIt
3. Tweak the last line: "... /usr/local/bin/gfnsvocl_linux_x86_64 23 156399 156400" to the range you want to run.
4. Run (play button in the upper left).
5. Leave the browser window open. If anything breaks, try "Runtime -> Reset all runtimes..." and start again. GFN sieve has checkpoints, so you can continue at any point.

Genefer is run similarly (I have a script for those interested), but I'm not sure how to get it run with BOINC. If someone knows how to integrate BOINC to Colab it would be great, else could we use it for manual GFN double checking or something like that?

Anyway... for those into MSR, have fun with some free GPUs ;)

How do you get "gfnsvocl_linux_x86_64" in it?

When you register a Manual Sieving Reservation you get to an Instructions page where you can see the input line you have to use and where you can download the executable needed.

I think you need to select GPU via Runtime -> Change runtime type

Since the K80 is a two-chip card, has anyone been able to run two instances of Msieving on it? I can only get one to run.

EDIT: Ah, apparently you only get one GPU.

What I've observed over the last couple of days is that Google Colab gives out packages of "1 GPU - 12 hours runtime" before you have to restart the script. Here is a cheap trick i tried out the last days: If you copy the sieve script (with a different command line) and use a second folder, you can run two GPU tasks at once in two browser tabs. However, assuming you start them at the same time, both will stop after 6 hours with an error message that no host with GPU could be found (and after 4 hours if you use 3 scripts etc.). After another 6 hours (or 8 hours in case of 3 scripts) host can be found again. So it seems that with this trick you don't get more computational resources but rather you can only use up your computational "budget" faster.

I've been steadily crunching a 25P range for GFN22 every day this week. Going to up that to 35P, which should still keep me below the 12-hour limit.

HI
@matzetoni
Thanks to you we have great "fun" :)
Regarding the 12h limit, how many pauses do you have to do to add a bud before this period?
I wish you success and script development

If one runs multiple scripts at the same time and pause the scripts now and then, it is hard to predict when exactly Colab decides to give GPUs to you or take GPUs from you. Overall my observation is that it does not give you any advantage compared to running only one script 12 h straight (even worse: you have to organize more scripts). Of course no one stops you from creating a second Google account...

Thanks to user Dylan14 at mersenneforum, we can run boinc / PG on Google Colab using the following script. There is no need of Google Drive here, so you can just copy the script, insert your account key and run it.

import os.path !apt-get update !apt-get install boinc boinc-client !cp /usr/bin/boinc /content !cp /usr/bin/boinccmd /content if not os.path.exists('/content/slots'): !mkdir slots if not os.path.exists('/content/slots/0'): !boinc --attach_project "http://www.primegrid.com/" "account key here" else: !boinc

Note: for me it automatically chose the 'home' settings, so check the project preferences and computing preferences the host uses. Colab hosts have only two CPU cores, so obviously you shouldn't choose SoB tasks as the tasks should finish within 12 hours. For now I only ran PPSE on CPU (1 task (single core) needs ~ 30 min), but GPU should also work if enabled. Feel free to post your times for different subprojects :)

Am I doing something wrong, or is the there really no way of saving the state when your 12 hours are up?

At least I don't know one. This script works entirely without Google Drive. If you mount your Drive, you could save your checkpoints. But part of the problem with continuing your work is that when you start a new Colab session you don't necessarily get the same instance you had in the previous session. And BOINC does not simply continue a task on a new host that was originally sent out to another host. Because tasks that get lost when your instance aborts are only resent after timeout, I would recommend using this script only for short tasks, mainly GFN15 / GFN16, where the timeout period is short.

If the two "sessions" run under the same PrimeGrid user, I think it is certain that you never get a task from the same workunit a second time. /JeppeSN

I am finding that the environment is stopping after a while. I think it may have been because I had set the "Maintain enough work for an additional" parameter to 0.00001 days. I have put it back to 0.0005 days and I shall see how that goes.


At least I don't know one. This script works entirely without Google Drive. If you mount your Drive, you could save your checkpoints. But part of the problem with continuing your work is that when you start a new Colab session you don't necessarily get the same instance you had in the previous session. And BOINC does not simply continue a task on a new host that was originally sent out to another host. Because tasks that get lost when your instance aborts are only resent after timeout, I would recommend using this script only for short tasks, mainly GFN15 / GFN16, where the timeout period is short.


I am trying to add a line:

!sleep 39600 && boinccmd --project "http:/www.primegrid.com" --nomorework


so that I do not abandon tasks when it finishes.

It's not working for me any more. Not sure why. The latest run managed to complete 5 WUs before dieing and lasted something like an hour.

I noticed the terms of service for colab say no cryptocurrency mining.

https://research.google.com/colaboratory/faq.html

Please note that using Colaboratory for cryptocurrency mining is disallowed entirely, and may result in being banned from using Colab altogether.


I'm not sure they'll like people using BOINC either.

Really shouldn't someone clarify with google whether this is okay. Maybe it would be okay if we followed certain rules. Maybe they would want us to mount the software on google drive so we don't download it everytime.

I have only done the occasional GFN Sieve on Google Colab as I don't want to abuse the free platform. I noticed today when I just started a sieve that the GPU type was different. It wasn't showing the Tesla K80, but a P100.

D0: "Tesla P100-PCIE-16GB"

I'm not sure if this change will be reflected in every session or if Google is doing a progressive changeover as they replace old hardware.

Since Prime Grid distanced itself from GridCoin I'd hope helping to find Prime Numbers would be a good thing.

I too have begun to get Tesla P100 16GB GPU's on Google Colab.

I was able to do 100P of GFN21 in the allotted 12hr window.

It's important to note that you don't want to run these constantly. I had some issues with the P80's where after a few consecutive sessions back to back for a few days I'd get a connection error of no GPU or no backend available. This is Colab limiting high intense computing. I haven't tried to reach my limit with the P100's but I imagine it's the same deal. If you run them constantly you get flagged for high intense use and they limit you for a brief time of a few days. I took a week or so off and went back to and had no more issues but was lucky enough to now get P100's which seem to be nearly 3x as fast.

I just signed up today for their free 750 hrs/month. I have one instance running (1 vCPU only) and will see how things go.

Has anyone tried to see how many such 1vCPU instances we can request? I went through a mock request for a second such instance (1 vCPU, 750 hrs/month) and it is not objecting.
