Double-check request
 

We are running a long-term QA process on [URL="http://www.mersenneforum.org/member.php?u=170"]Ernst Mayer's[/URL] [URL="http://hogranch.com/mayer/README.html"]Mlucas[/URL]. Usually we run double-check work because that gives us immediate feedback as to the validity of our calculations.

However, occasionally we like to run a first-time test to test different FFTs and to push the program harder, by running it longer.

We currently have finished [URL="http://mersenne.org/report_exponent/default.php?exp_lo=67167619&exp_hi=67167619&full=1"]67167619[/URL] and we are looking for someone to run a double-check on it so we can get feedback now rather than waiting a few years for the double-check wave to get into that area.

We have interim residues recorded for every 1,000,000 iterations in the text file attached to this post.

Thank you for your assistance!

I was going to volunteer,
but when I tried to get a manual assignment for it from primenet,
I get
Error code: 40
Error text: No assignment available meeting CPU, program code and work preference requirements, cpu_id: 952745, cpu # = 0, user_id = 127955

Any ideas on how I can get the assignment ?

I am your man. BRB with the ETA in few minutes.

ETA 43 hours (your former Titan, now you feel sorry that you sold it to me :P)

[QUOTE]ETA 43 hours (your former Titan, now you feel sorry that you sold it to me :P)[/QUOTE]Every time we play [url=https://kerbalspaceprogram.com/about.php]Kerbal Space Program[/url] we miss that card. We bought a [url=http://www.evga.com/Products/Product.aspx?pn=02G-P4-3753-KR]750Ti[/url] to replace it. It works okay, but it ain't no Titan.

For your (early) peace of mind, the first 10M iterations are matching.

Done.

Thanks to Mike for doing those -- no sure if he thought I was feeling lonely, or wanted me to be able to focus of development/debug without having to worry about doing long-run QA as well.

(I do 24/7/365 big runs on my Haswell, but that is with the code in Fermat-number run mode. No other high-end hardware in my little "farm", which is really more akin to a small urban gardening plot than a farm.)

If starting it in about 40 hours (and finishing it about the mid of next week) is not too late, than it will be mine, again.

No rush!

Thanks!

Done. Reported. [URL="http://www.mersenne.org/report_exponent/?exp_lo=70885853&full=1"]Match[/URL].

queued. it will take some time, no core free right now.

Matched.

It's assigned as a TC. Do you still want me to quick check it?

It must have been reassigned right after we turned it in.

Hopefully they finish it in a reasonable amount of time.

I stumbled on this old thread. I noticed the assignment had expired for triple-checking 35888737 so I added it. Should have an answer in 14.5 hours as to whether your result or the other old one was correct (assuming mine matches either) :smile:

Congrats, it's a match:
