[QUOTE=kriesel;528911]am no longer trying P-1 since the selftest failed.
[/QUOTE]That was in regard to CUDAPm1 v0.20.
Currently I'm running gpuowl (Fan Ming's executable), P-1 on Colab (Tesla K80). Its selftest passed, finding the known factor.

Anyone tried using 2 accounts on Kaggle? Running 2x 30 hours GPU per week and up to 20 CPU instances?

I'm tempted to do it since I scripted the restarting, but I do not want to be banned.

Irrelevant to the question here but how do you manage 10 CPU instances? With a script or something? I am interested to use them to crank out some cofactor or ECM tests.

For the two accounts thing, I believe you need a phone number to access GPU so you would need multiple phone numbers and obv email accounts.

Yeah, I forgot about the extra phone number needed. :sad:

I started all 10 instances manually the first time, and then I use Kaggle API to download files after it is done and restart the instance, as I described in post #424 and #443.

I have an ftp I use to download the files inside the notebook scripts and I upload the worktodo.txt and temporary files afterwards.

The notebook scripts are:

[CODE]import os
%cd /kaggle/working
!wget ftp://<ftp address>/kaggle/mprime.tar.gz
!tar -xzvf mprime.tar.gz
!wget ftp://<ftp address>/kaggle/kaggle1/*
!tar -xzvf files.tar.gz
!chmod 755 *
!./mprime -d >> output1.txt
[/CODE]

The mprime.tar.gz is just the mprime program and I have 10 folders kaggle1 - kaggle10 with files.tar.gz, these files contains the individual prime.txt, local.txt, worktodo.txt, output.txt and the mprime temporary files.

In post #443 I explain how to rename the instance the first time, so my instances are called kaggle.com/<username>/mprime1 (to mprime10).
When they are done I use this Linux script to download and upload files and restart the instance:
[CODE]#!/bin/sh
cd tmp
rm *
cd tmp
rm *
cd ~/kaggle/
~/.local/bin/kaggle kernels output <username>/mprime$1 -p tmp/
cd tmp
mv output$1.txt tmp/
mv worktodo.txt tmp/
mv results.txt tmp/
mv prime.log tmp/
mv prime.txt tmp/
mv local.txt tmp/
rm files.tar.gz
rm p*.bu*
rm prime*.*
mv p* tmp/
cd tmp
tar -czvf ~/kaggle/tmp/files.tar.gz *
cd ..
wput -u -nc files.tar.gz ftp://<ftp address>/kaggle/kaggle$1/files.tar.gz
cd ..
~/.local/bin/kaggle kernels push -p ~/kaggle/$1
[/CODE]

Then I just run this script 10 times from another script with numbers 1 to 10 as input.

Edit:
The last line is where it restarts the instance: ~/.local/bin/kaggle kernels push -p ~/kaggle/$1

In the kaggle folder I have folders 1 to 10, and each folder contains mprime$1.ipynb and kernel-metadata.json, see post #443.

[QUOTE=Dylan14;529113]You need to have gmp installed on the instance first. Either you can compile it from source, or you can run

[CODE]!apt install libgmp-dev[/CODE]and then you should have gmp.h in the place gpuowl expects.[/QUOTE]

Looks like an older GCC/G++ version to me. I had the same issue until I updated my GCC & G++ to version 7 or above (I'm currently running gcc-9). I didn't compile mine on colab or kaggle, instead, I compiled it on my own Linux machine with ROCm on it, so I don't really know how to fix that on either cloud platforms.

I have changed it to #include <experimental-filesystem> before, which resolves this specific issue but others pop out.

I had the same issue. You will need to have at least gcc version 8 for this to work. Luckily, gcc-8 is available in the Ubuntu repo:

[CODE]!apt install gcc-8[/CODE]

Alternatively, you may replace #include <filesystem> with

[CODE]#include <experimental/filesystem>[/CODE]

in the gpuowl files, and link with

[CODE]-lstdc++fs[/CODE]
It might be a good idea to let preda know this so that he can make the appropriate changes.

Just got my account on Kaggle blocked - Not sure if it's worth making a new account or contacting support(doubt I'll get far with the latter).

did you check the g++ version,
g++ --version

I think that a reasonably recent version of gcc/g++ (8 probably) should find the #include<filesystem>. (I don't have another fix for that).

I didn't build myself on collab, so I don't have first-hand experience there. I'll review pull-request on github with fixes.
