New project mersenneathome.net

[AMDave]

CAUTION: 5MB upload per core per 20mins

There is a new project on the web:
http://mersenneathome.net/

It has been put up by Sebastian (b0b3r) Bobrecki
http://mersenneathome.net/show_user.php?userid=1

As far as I can tell he has a background in Hash decryption and Rainbow Tables

Dingo has asked in the forum for him to post the group or organisation that it is running for.

The client apps are for LINUX ONLY at the moment

The wu's come down with an estimate of 90 minutes
They complete in about 18 to 20 minutes.
Points are good
BUT every WU is uploading over 5MB back to the server

That is just HUGE and totally unnecessary.

It just raises other questions.

It just took me an hour to un-bind my network which was overloaded with 135 MB of uploads and his I/O rate is not great.

Be cautious if you hook up to this one.

I don't run Linux yet, but thanks for the heads up AMDave those figures for upload are just ridiculous. I will stay away even if I do get a Linux box anytime soon!

[vaughan]

I've joined but don't have too many Linux boxes at the moment. On the project's forum they say a Windows application is on the "to do" list. Also the current tasks are testing previously known / tested numbers.

[AMDave]

Bok has it in the Free-DC stats already.
Bobcat13 is kicking it ;)

[Nflight]

Psst its Windows Time :blob3:

[liuqyn]

heads up, NOT download friendly. around 3.5Mb per wu.

[AMDave]

Yeah. That was a nasty surprise last month when we kicked off.
I posted about it but they said that is the way it is.
It is not going to change.
So I have gone into trickle mode -> manually let in 3 wu's before I go to bed and they 'should' upload during my off-peak hours.

/ed - hmm. I could use my VMs to my advantage here. Got a couple of milestones to hit first though -ed/

[liuqyn]

is it just the new app that reduced to file size, or is the linux one still in the 5Mb range?

[AMDave]

For the linux client it is 3.5MB d/l + 3.5MB u/l per wu (ie per core) per 15mins
On a 6 core machine 7MB per core per 15mins
so 168MB per hour
or 4 GB per day
and about 120GB per month
and that's just for 1 machine which would hit my max d/l limit in 8 days
its. um. unfortunate.

I completed my 10K, and that is it for this monstrosity, That is a lot of uploads and downloads, and if you have limits and I don't at this time, BEWARE! :sad5:

Thought I would give this a try with the new windows app so signed up. Initially got 1 task which was waiting its turn to run as I am also running Androinc. Over night mersenneathome sent me 360 more tasks...Ka-Boom!!! I think I'll do about 10k and stop. The project has already sent me over 6k worth in one night!!!

[AMDave]

Slippery little sucker isn't it!

[AMDave]

I have arrived at a somewhat convoluted solution that I hope will net me about 120 work units per day
I split-off the CPU work from the host boinc client so it is now running GPU only except for the geez-its-hot-here window from 12:00 - 17:30
I raised a VM to run only mersenne on all cores from 00:00 until 07:00 but with network limited to 00:00 - 06:00 to suit my off-peak D/L times from my ISP and the fact that someone else starts using the internet connection at 06:00
I raised another VM to run Androinc from 07:00 until the start of the geez-its-hot-here window at 12:00
Then I raised another VM to run Androinc from the end of the geez-its-hot-here window at 17:30 until 00:00

Then I replicated that solution to another machine.

The VMs are x686 so both mersenne and Androinc are completing slower than before

After 24 hours it is all fitting together ok.

But hey, I should get about 2000 per day on mersenne!!! =O

Maybe next week, just to cement the idea that I really do not have any prospect of 'getting a life', I'll upgrade the VMs to 64-bit and look for performance improvements.

No LOLs please.

[liuqyn]

good news, new work units take 4x crunch time and grant 4x credit, upload/download is still 3.5mb each way just not as often.

[liuqyn]

BTW, project seams fairly stable, should we open this up to the general forum?

[AMDave]

you are right, it is stable at this point
Although the d/l u/l situation is bad compared to other projects it is not erratic.
They are continuing to make incremental improvements and they are still producing work
so I'd second that.

[NeoGen]

Is this project on the public threads by now as liuqyn asked a while ago?

I just started running it a few days ago, put 2 cores on it and it runs good so far, but on the flipside I have already over 50 pending tasks... seems like it takes a while until someone comes by and does your workunit.

[AMDave]

Ahh, well done.
That was nice recovery there Vaughan.
I didn't quite catch you napping in spite of my misdirection.
I'll have to try harder next time. :biggrin:

[vaughan]

Yikes I got a scare. It took some time to turn the "battle fleet" around. Still want some GHz to play with over at BURP Renderfarming. As a team we can grab world #2 soon on that project.
