```Hello Paul,
>I'm also interested to know which polynomial you found, so that I can compare with the current development version of CADO-NFS.
I attached our polynom.

>what does the y-axis represent?
It represents the days needed since the beginning of the phase.
>Do the colors between the first graph and the second one correspond to each other
The colors are the same, but they are not related. Maybe it would be better to set just one color to the bars at the eta graph.
>When I click on the 03 Jan 17 column in the first graph, I see "ETA 52.40". What does it mean?
That they ETA since the beginning is 52,4 days
>Should the green part (Elapsed time) fill the whole rectangle when the sieving is finished?
yes.

Greetings
Micha Grüninger

Dear Micha,

corresponding feature request ticket:

https://gforge.inria.fr/tracker/index.php?func=detail&aid=16699&group_id=2065&atid=7445

Indeed it would be better to use Python for the scripts.

Also, I don't really understand the first graph on http://149.201.240.24/:
what does the y-axis represent? Do the colors between the first graph and the
second one correspond to each other? When I click on the 03 Jan 17 column in
the first graph, I see "ETA 52.40". What does it mean? Should the green part
(Elapsed time) fill the whole rectangle when the sieving is finished?

I'm also interested to know which polynomial you found, so that I can compare with
the current development version of CADO-NFS.

Best regards,
Paul Zimmermann

> Hey guys,

> I have written some scripts to visualize progress and participation. Of course, the scripts are not perfect, but they work for me yet, and I think they are a good start. If you want to see it in action visit: http://149.201.240.24/ . Since you shared your cool program, I think it is just fair to share my work. It consists of these three files:
>
>   *   data_eta.php: Reads the log, extracts and process information about the ETA. Saves it to a file that needs to be shared by a webserver.
>   *   data_list_wus.php: Extract information from a SQLite3 DB, process it and saves it to a file that needs to be shared by a webserver.
>   *   index.html: Takes to output file of the 2 previous scripts and visualize them. Needs to be shared by a webserver. This is the file the user sees.
>
> Some words about the example page:
> We are a group of students at FH-Aachen, and we are factoring a 200-digit number. We computed the polynomal selection with the GPU-version of Msieve, and are now using cadonfs for the second Step. Because our server crashed several times we have slumps in the ETA at the 23 and 29 December.
>
> I see that it is not optimal that I used PHP to code the data generation scripts, because users must install another interpreter to use them. Feel free to convert them to another script language, if that bothers you.

> I attached the files.
