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.

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
Pozdr.

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 played with this briefly but BOINC did not detect any GPU, only two CPUs. Did I miss anything?

I played with this briefly but BOINC did not detect any GPU, only two CPUs. Did I miss anything?

Have you selectected GPU via Runtime -> Change runtime type ?

Message 134136 - Posted: 22 Oct 2019 | 16:20:25 UTC - in response to Message 134110.

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.

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.

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.


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.

Same here. The last days I always got P100s, about three times faster than the K80.

Still working for me, although the last 2 runs (weekend before last and today) gave me Tesla K80's.

Had you been using the service a lot? I think someone mentioned further up about restrictions for repeated high usage.

It has been a few days since your post, so maybe try again if you haven't in the meantime.

I do give it a break from time to time. In the most recent run it has never got beyond allocating. So I am just letting it allocate for as long as it wants.

I saw a T4 GPU one time on Colab. Only K80's and P100's every other time. Specs for the T4 put it similar to a 2070 Super in terms of CUDA cores. I did not benchmark it properly but I imagine it could easily do 250-300P in the allotted 12hrs.

One time only, and have not gotten one since.

I successully ran a GFN21 task in about five hours on a P100. This is faster than a 2080 Ti; evidently those 4 TeraFLOPS of DP compute flexing their muscles. As far as I know, GFN21 and 22 (not DYFL) are the only projects that can still make use of DP on account of the OCL transform.

Anyway, could be useful for the upcoming challenge. If you can get a P100. :)

4096 bit memory config also on a P100.... that's a lot of bandwidth and GFN uses the card's memory fairly heavily.

This helped me so the GPU wasn't timing out all the time :)


So, run this script, BOINC will work on Google Colab? I'm going to try it now...

Message 136332 - Posted: 12 Jan 2020 | 16:20:08 UTC - in response to Message 135394.

I saw a T4 GPU one time on Colab. Only K80's and P100's every other time. Specs for the T4 put it similar to a 2070 Super in terms of CUDA cores. I did not benchmark it properly but I imagine it could easily do 250-300P in the allotted 12hrs.

One time only, and have not gotten one since.


In my limited anecdotal experience, it seems the T4 is slower than the P100 at GFN-18.

If you're using those for GFN manual sieving, please be aware that I recently discovered that lost connections during sieving means there are gaps in the factor files. My testing scripts weren't sensitive enough to catch them before, but they will catch them now. If your sieving has a gap in it, I expect you to fix it. I spent most of a day fixing gaps in past sieving where credit had already been granted. One of those ranges even belonged to me.

So while it can happen even if you're not using Google Colab, it's a lot more likely if you are.

I have been using colab. figured I would post up some numbers based on the different gpus I get. I have been able to get a single instance 12 hours a day or so and then a break of 12 hours. non gpu instances are available during that time, but I get timeouts faster, so don't bother.

Have been using the Google Colab on and off for about a month now to run PrimeGrid and the last week it automatically "times out" with message it is stopped "due to Inactivity" after about one to two hours.

I know it's free to use... was wondering if there is anything I can do to keep it up and running for more than a hour?

On a related question how can I also attach my WuProp account along with PrimeGrid if I can get it to stay active for more than 6 hours at a time?

Same for me for GPU instances. CPU only instances tend to last longer, but overall it seems there is less computing time given out now. We can only guess whether it is due to higher demand by universities or just a restriction they implemented.

Other than paying 10$ / month for their Colab Pro service, I don't see a way we could influence how long we are given an instance.

If I had to guess why it's doing this now, it's that Google is cheaping out on many of their giveaways. I'm involved with Startup Weekend, and they reduced the amount of free cloud computing from $3000 per person to $300. Their advertising business has taken a huge hit during the pandemic, and they were already trying to figure out how to stop hemorrhaging money.

If you get connection issues with colab please use this javascript in your browser (CTRL+SHIRT+I) (this presses the connect button every 60 seconds):
function ConnectButton(){
console.log("Connect pushed");
document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click()
}
setInterval(ConnectButton,60000);

On a related question how can I also attach my WuProp account along with PrimeGrid if I can get it to stay active for more than 6 hours at a time?


This is vexing me. I can't figure out how to add a second project. I've tried stacking a second --attach_project argument, I've tried a subsequent boinccmd --project_attach line, and I've tried boinccmd --join_acct_mgr to add both projects at once via BAM! But none of it works.

I've splashed out for the Colab Pro, which at first was getting me a full 24 hrs with the GPU. But now I'm lucky to get 2 hrs. I just canceled Pro as it's just not worth it.

mattozan,

Thanks for the reply. I had tried the same "tricks" as you for a second project with same ineffective results on CoLab.

I must of been very lucky... just had a free CoLab session with GPU run for about 12 hours after not using it for almost a month.

Guys see the above three computers. Do they all have AVX512?
Can the two with GPUs finish their corresponding long tasks in time? That is, 12 hours?

Also, according to my experience with Colab: P100>T4>K80
Haven't gotten a V100.

EDIT: Seems the P100 is extremely stable in performance, at least with GFN17 Low. Always 5min plus 1 or 2 s. (301~302s).
Gonna try GFN18 and 16 and 17meg.

Okay I think Colab is cutting down. Haven't gotten a session with over 3 hours even though I stopped for a week. Well I must stop longer it seems.
Also T4 seems to be faster than P100.

This helped me so the GPU wasn't timing out all the time :)

This one worked for me, but I'm only getting around 6hours per week.

Hello everybody
Does it still work?
Is it possible to continue with the machines that shut down at 12 hours?

Thank you ^_^

They don't shut down at 12 hours, the free ones shut down any time google feels like shutting them down.

GPU instances don't last more than a few hours for me, but CPU-only instances still seem to stay online for at least 12 h. I think they have introduced a maximum of weekly GPU usage.

AFAIK you can't continue BOINC calculations after a machine shuts down, you will get new tasks when you restart the machine. BOINC doesn't recognize the machine after a restart and will treat it like a new machine. This is why Colab is only suited for short tasks - so no conjecture projects or GFN20+, but PPSE or GFN15/16.

In general though it is possible on Google Colab to resume computations by making a save file in your Google drive which the machine can access. When starting a machine, give it access to your Drive and it will be able to resume computations from that checkpoint file. Since BOINC makes saves only locally on the machine - not in your Google Drive - it loses all progress after shut down.

Have you explicitly requested a GPU instance? For that you need to go to "Runtime" -> "Change runtime type". Then select "GPU". If it is "none" you will only get CPU instances.

Since you seem to know how it works and I don't would it work for any Boinc Project ie Asteroids or whatever or even non Boinc Projects ie Quarrantine https://quarantine.infino.me/ or even Folding @Home https://foldingathome.org/ ?

I'm not asking specifically about gpu tasks but cpu tasks as well. I realize this is Prime Grid and the Admins would much prefer we keep this on topic so it's just for info purposes that I'm asking not an actual how to do it at Project X beyond PG. I also realize the time limitations you guys have been discussing before restarting it so some Projects ie Climate Prediction are simply unfeasible.

Just like PG any other BOINC project can be run , you would only have to change one line in the code below, specifically the project link which should be shown in BOINC e.g. when you click "Properties" on a project in the projects tab (GUI). CPU tasks are done too, if you have set the project's preferences right. Note that Colab machines have only 2 CPU cores, so only run small tasks. I have no experience with the non-BOINC projects but as long as they have a Linux executable and the tasks are short enough it should be possible to run them on Colab machines, although the set up might be a bit more complicated than for BOINC.
