Below is a commented section of a Colab script. I do not remember who posted the script, or where, but I kept a copy as an example

[QUOTE]# 5 ECM factoring, smallish Mersennes
# 6 factoring Fermat ECM
# 7 factoring Cunningham ECM
[B]# 8-99 reserved[/B]
# 100 LL first time test
# 101 LL Double check
# 102 LL test world-record[/QUOTE][I]Prime95[/I] says work preference 8 as actually, "ECM on Mersenne cofactors." I tried this with [I]Mprime[/I]. It accepted it also. The working part of the script does not preclude it. The comments give the appearance that it is not available.

:smile:

That comes from kriesel’s Google Colab reference thread ([URL="https://www.mersenneforum.org/showpost.php?p=527910&postcount=3"]https://www.mersenneforum.org/showpost.php?p=527910&postcount=3[/URL]. Good spotting.

Updated [url]https://www.mersenneforum.org/showpost.php?p=527910&postcount=3[/url] regarding worktype 8. Please update any copies you may have. Thanks for flagging it.

The only reason I noticed it was that I used this on my laptop a while back. I was poking around in [I]prime.txt[/I] and saw [I]WorkPreference=8[/I] there...

There seems to be something afoot again:

Sorry. Stupid SysAdmin Error. Please re-run the Notebook; things are back to nominal.

Thanks :)

[QUOTE=chalsall;532432]Sorry. Stupid SysAdmin Error. Please re-run the Notebook; things are back to nominal.[/QUOTE]I have a couple of exponents that have suffered loss.
During the downtime 95467157 completed, but does not show that it did. Then 95468381 completed and disappeared from my assignments page once it completed.
Edit:
Also, I am working on 95463631 and it is not showing up on my assignments page.

Compiled new version of gpuowl for Google colab.
ipynb:
[CODE]import os.path
from google.colab import drive

if not os.path.exists('/content/drive/My Drive'):
drive.mount('/content/drive')

%cd '/content/drive/My Drive/gpuowl-master/'

!cp 'gpuowl.exe' /usr/local/bin/
!chmod 755 '/usr/local/bin/gpuowl.exe'

!/usr/local/bin/gpuowl.exe -use ORIG_X2,MERGED_MIDDLE[/CODE]
replace the "gpuowl-master/" with is the actual directory the binary located in Google Drive.

[QUOTE=Uncwilly;532447]Update:[/QUOTE]

OK. Thanks, for the detailed report; I'll be able to clean this up tonight. If anyone else sees anything like this, please PM me with the assignments in question.

Sorry for the issue; I discovered the hard way that the web-based "VPN" "back-end" console into my new "cloud" dedicated servers doesn't work under either Firefox nor Chrome under Linux.

Not amused...
