Yes, I can confirm this behavior too. Has been happening for the past couple of hours.

I need your expertise again regarding a current gpuowl binary with proofs so that I am up to date with the current status of the project. Thank you very much!

Does somebody have an executable of the latest version (wich generates Proofs)? I tried to run make under colab but got strange error messages. I don't have a Linux installation with rocm / nvidia drivers available either.
Fan Ming hasn't posted in the forum for a while, I think.

Wow! I just got Tesla V100-SXM2 instead usual P100.


V100 around 1.75 faster than P100 on PRP.

I wonder if we will get the same run time with these faster GPUs.

Default V100 first day

My four concurrent sessions on the paid tier of Colab each ran for 12.5 hours, each with a Tesla V100. My GPU72 statistics really got a boost from this.

I don't know yet how long I have to "rest" before I can restart the paid sessions.

The increase starting in February is due to switching to the paid tier.

Isn't ROCm both linux specific and AMD gpu (no NVIDIA) specific? https://github.com/RadeonOpenCompute/ROCm
The attached zip file is the result of a build of gpuowl-v6.11-366 on Google Colab on August 1 2020.
Probably built by the following:
Code:
#draft Notebook to set up a gpuowl Google drive folder for a future Colab session
import os.path
from google.colab import drive
import sys
if not os.path.exists('/content/drive/My Drive'):
  drive.mount('/content/drive')
%cd '/content/drive/My Drive//'
!chmod +w '/content/drive/My Drive'

if not os.path.exists('/content/drive/My Drive/gpuowl'):
  !mkdir '/content/drive/My Drive/gpuowl'

%cd '/content/drive/My Drive/gpuowl//'
print('git clone')
!git clone https://github.com/preda/gpuowl

%cd '/content/drive/My Drive/gpuowl/gpuowl//'
!apt install libgmp-dev
!update-alternatives --remove-all gcc 
!update-alternatives --remove-all g++
!apt-get install gcc-8 g++-8
!update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 10
!update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-8 10
!update-alternatives --config gcc
!update-alternatives --config g++
!g++ --version
!chmod +w '/content/drive/My Drive/gpuowl/gpuowl'
print('make gpuowl')
!make gpuowl

!echo create config.txt, worktodo.txt before continuing
print('customize to make a specific new gpu model\'s folder ready')
There's also Fan Ming's somewhat earlier version at https://mersenneforum.org/showpost.p...&postcount=958, made weeks after the introduction of PRP proof capability in gpuowl. It may not have the niceties of file cleanup etc. In general, the place to check for this sort of thing is https://www.mersenneforum.org/showpo...39&postcount=4, where I log and link to what versions have been posted. Linux posts are rare but they do happen.

Default Many reported google drive outage Tuesday

Might have affected Google Colab users using google drive also. Teachers complaining. https://www.cnn.com/2020/09/08/tech/...age/index.html

One of my accounts suddenly stopped getting GPU resources at all. For the last 72 hrs, it could not connect to GPU runtime for even once (usually it can use about 30~80 minutes every 24 hours).


I don't know if this is related to the fact that I started to use its CPU for P-1 factoring just shortly before this happened. (Used GPU for TF at ~13:00 one day, started a new notebook to do P-1 at ~21:00, then when I stopped P-1 and tried to use GPU at ~14:00 the next day, it couldn't connect to runtime and never ever could since then.) Interesting enough, I do P-1 on another free Colab account too, but access to GPU on that account is normal (at least until now).
