DHEP future

[michaelgarvie]

Dear contributors,

Due to the fact I will soon be leaving the lab I'm at, and will have no permanent abode for quite a while, DHEP will have to be shut down. This is UNLESS someone would like to host it. I am willing to cooperate with this person to set it up and keep it running.

Miguel

[IronBits]

You have PM :D
We can work something out I'm sure.

[IronBits]

^ Bump ;)

Hi IronBits,

If you want to look at being the primary, I think I can act as an emergency/secondary backup if needed. Would need much hand-holding in order to get the thing setup etc. Have sent a PM to Miguel regarding the situation.

Cheers,

prok

[ace_dent]

Miguel,

I hope the hosting problem can be resolved soon so that this worth-while DC project can continue... however, in the mean time could you please update the main website and News section (and maybe take stats offline), to reflect that the project is down until further notice. (Purely for the sake of public relations!)

Regards,
Andrew

[IronBits]

He finally responded... let's see what develops ;) :cheers:

[prokaryote]

:cool:

[nickbrownsfan]

:drums: :thumbs:

[prokaryote]

IronBits, any news on this yet?

[IronBits]

He asked if we could load up the Java Server software for him.
I asked Bok if he would handle it ...
I haven't heard back from Bok yet.

He has not sent me anything yet...

[Bok]

You did ?

I haven't seen anything from you on that????

Bok

[IronBits]

I hope it wasn't from the mail problems :rotfl:
I'll see if I can dig it up... actually, can you install the Java Server stuff IF he gets back to me?

DJ

[Bok]

Sure.

Bok

[prokaryote]

Hi Bok, IronBits;

So what's shaking in the DHEP world? Noticed that the stats page is back up and the project appears to be running. Will it be transfered to another site?

[IronBits]

I have no clue what is going on.
He never responded to my last email message.

[ace_dent]

Any chance of an official update? :confused:

[IronBits]

He just sent me another email, asking the same thing, so evidently, my last response never made it to him.
I responded to him again, asking that he expidite making up a .tar file and any instructions, send it to me, or provide linkage, so we can get it up and running asap for you guys.

DJ

[prokaryote]

:|party|: Cool!. Thanks for doing this IronBits.

[IronBits]

Progress!
I just recieved a large chunck of it.
Bok is busy installing on the new server as I type this.

He didn't mention which Java was needed, so Bok is going to start with Sun ...

I don't know how many more pieces he needs to send me before the project is up and running once again...

I hope the new Dual Xeon 3.6GHz Nocona CPUs are up to the task. :rotfl:

And thanks to Dyyryath when he put Gentoo 64 on it.
He gave me a backup routine that mounts a 2nd spare drive, then copies all the important stuff to it, then unmounts it to keep it protected. :thumbs:
It's on a large UPS, and my DSL service has been very reliable for the past 4 years.

Hopefully we'll be good to go soon. :)

[Bok]

Update

installed the db + tables and users no problem.

configured the software no problem

sun jdk is masked for Gentoo right now so instead of forcing it I tried

1. blackdown 1.4.2, no go, many many errors on starting the server

2. ibm 1.4.2, less errors but still many

I'm presuming it's not compatible with anything but Sun but will wait on a response before going any further?

Miguel?

IB, can you email miguel too and let him know

:cheers:

Bok

[ace_dent]

Excellent news! Can't wait to get my computers evolving :bouncy:

[IronBits]

email sent.

[vaughan]

Great work, thanks for your efforts and the nice server box. :cheers:

The project was down last night my time - was that the server being swapped over?

[IronBits]

Bok has been busy installing the java server part, and there are some problems.
I don't know how long it will take to get it working yet...
I think Bok said he has to install the X server stuff...
why java needs X is beyond me.

Hang in there...

[IronBits]

Dyyryath stopped by and did some 'stuff' on the Server today.

Waiting on Bok to take a look to see if it's good to go now :)

so we are getting closer...

[nickbrownsfan]

Thanks for the update. You guys rock :drums:

[Bok]

I'll get on when I get to the hotel in a couple of hours :)

Bok

[IronBits]

Master Dyyryath to the rescue!
Jeff has taken more time out of his busy schedule to put his back into it.
He spent a good deal of time on the Server last night and sent me an email.

I've got the server updating all of the installed packages. I'll check
on it's progress tomorrow. Once that's done, I'll install the necessary
X libs to make your DHEP server work correctly.

:allhail:

[IronBits]

Testing of the Server will begin shortly, by Miguel :)

[ace_dent]

Any news? Twitching to get evolving...

[IronBits]

Not a word, since his last message saying he was in a motel room and on dial up, and he would check out the server part and get back to me.
He did say the client was able to fetch and send results tho :thumbs:

[HitchHiker]

And?

Any news? :Pokes:

I just found this subject and am amazed that no email was sent. Is Miguel so fed up with this project that he didn't bother to tell some 2000-3000 contributors to his project what going on? :bonk:

Is this project dead? :stretcher:

is Miguel gone hiding? :sofa:

Or has this all been a joke? :stomp:

[ace_dent]

Well~ as I understand it Miguel has finished his PhD, so officially the project (at Surrey University) has finished. However, I think Miguel wants to carry this on- but remember: it's in his own personal time, and the objective of the project are his own. I wish Surrey Uni had gone to a postdoc, or another PhD at least to continue this excellent work. I have decided to switch to BOINC- which now has many worthwhile projects.

Andrew

[HitchHiker]

All very nice, why didn't he tell us? :bang:

Is this too much to ask, from an academic, these days?

[ace_dent]

'HitchHiker'- before you get too frustrated, remember this is just my understanding (I could be wrong). However, the info I presented is based on postings from this forum so Miguel did tell you (in the vaguest sense).

See here (http://www.free-dc.org/forum/showthread.php?s=&threadid=7761) and the first post of this thread!

Andrew

[IronBits]

I know he's on the road, and rarely has access to the internet...

He sent me all the files to install the Server on Jan. 18th.
We (Bok + Dyyryath) just got it working (we think) about a week ago.

Waiting on miguel garvie to let us know if we done well ...

From his 1st original post

and will have no permanent abode for quite a while

Hang in there ... :cheers:

[IronBits]

News update! :)


Hi Ironbits,
I've been away recently, just moved to New York for 4 months. Unfortunately I can't access my web mail at the place I'm working at but I should be able to log into servers and try and get dhep running on your servers.

[IronBits]

More news

Great, it's working now. I started the server on stats and ran a client in england and it works. I'll prepare the packages for the next stage of installation!

[IronBits]

Hi guys,

The dhep server is working!! :|party|: :elephant:
What was needed was the mysql jdbc library in /jre/lib/ext and now its working on blackdown.


He uploaded stage2 files, Bok should be able to get that done soon, or I'll attempt it tonight when I get home.

Only 1 more step to go after this! :cheers:

[Bok]

Ok,

just read the messages. Seems simple enough. I'll have to create a virtual address for now in apache, perhaps dhep.dbestern.com ?

IB, do you have DNS set up for all xxxxx.dbestern.com ?

Anyway, it'll have to wait until I get to the hotel tonight :)

Bok

[IronBits]

I'll get dhep.dbestern.com setup on DNS tonight when I get home.
You going to do the Vhosts ? ;)

He put a vague note up, in a supermarket on the other side of town you mean. The supermarket I only visit once every 3 months or so. Many people probably don't even know of it's existense.

Miguel promised us, when we give him our email-addresses, that mass mailing would be kept to a minimum. Well, how low can you go? As far as I can remember there never was a mass mailing. This would have been the perfect opportunity to have one.

[ace_dent]

Great to hear some progress!
- Good luck with it all.

:elephant:

[HitchHiker]

Things seem to be happening.
One of my machines even did some work yesterday according to the stats, the others needed a kick to start and now seem to be crunching happily again.

[IronBits]

Finally - we have something to show ! :D

http://dhep.dbestern.com/

Be patient as we continue to find bugs and/or fix features ;)

Just showing all of you, that are intrested in this project, that we are getting very close ...

Everything works except the stats now. (I think)

Will have to wait on Bok to figure it out, or Miguel to tell me what I need to do.
Email was just sent...

[IronBits]

Bok doesn't make the stats your boxen create...
Bok makes the stats your boxen create look better. :D
:rotfl:

Thanks Bok! :notworthy

[Bok]

It was a simple fix :)

I just have the mysql users set up for localhost only, not IP driven....

I'll almost certainly get the final pieces done today too

Bok :D

Yey!! :|party|:

Well done chaps. Let the fun begin...

[IronBits]

Feb 22 2005: Beta test of the new DHEP server has begun and will finish on Monday 28th. To migrate to the new server you must change the following in your scripts: every time it says 139.184.166.27 should be changed for stats.dbestern.com. This includes the java.policy file and the launching scripts. Statistics will not be logged for this week to incur no disadvantage to those joining in the beta test. Beta test result will be announced on Monday 28th. If successful all users should migrate and stats collection will be resumed on Tuesday from the new server. If unsuccessful stats collection will be resumed on Tuesday from the old server.. Progress of the new server can be checked here. http://dhep.dbestern.com 66.51.209.121

[IronBits]

I see results from rshepard ! :elephant:

[rshepard]

Looks like we're back in business. :rock:

[ace_dent]

Not sure if it's useful to point out observations in this thread, but currently the 'Fitness Graph' for the current goal is not being displayed.

Cheers,
Andrew.

[Bok]

Yes,

that's because I haven't done a piece on the server I promised to do yesterday :(

My bad

:haddock: Bok :crazy:

[ace_dent]

Again, not sure how useful this...
I've noticed that it seems client connections are often being lost (maybe it's always been this way?). My main machine 'zero' has reconnected twice in as many days, and my 'ace_dent' laptop reconnected half a dozen times when left crunching overnight- now unplugged. This is based on multiple entries appearing for a single client on the Topology page; last night when I checked ~1/2 were actually 'dead' entries.

Cheers,
Andrew

[rshepard]

Looking at the daily stats, it appears that the running total didn't reset at midnight.
The dates changed OK, but the totals labeled as the 23rd are actually from the 22nd, and today's numbers contain the totals from yesterday.

Note to ace_dent: the "dead entries" have always been a part of the topology map--I don't remember the details, but I don't think they hurt anything.

[ace_dent]

@rshepard

Ok- thanks for the info. It might be my memory, but it seems these dead entries are more common on the new server?... Could be network issues at my end though.

[rshepard]

Woohoo!!! The fitness graph and the daily stats are working correctly now!!

:allhail:

[ace_dent]

Great stuff... To celebrate I think I'll start powering up some more boxes... :D

[DrkNexus]

I just noticed the project was back up, so I re-joined it. However manually configuring all my boxes to use the new server is going to take effort I don't really want to expend. Is there anyway somebody could automate this process? Second I just thought I should point out that when downloading the client from the server it still points to the old 139.?.?.? address rather than the new dhep.dbestern.com address (at least for the GUI version), if that is the case for other versions as well it is going to extremely limit new participants.

[Bok]

We are working on fixing the download. Unfortunately the addresses and such are embedded in a windows .msi install project and someone needs to work out how to use the relevant applications to fix this.

Stay tuned!

Bok

[DrkNexus]

That part is understandable, but since I noticed the issue with the GUI download version, which isn't encapsulated in anyway - and so should be an easy fix. It might be a good thing to temporarily disable the downloads so we don't get people attemping the project - finding no results - and being upset as a result.

[Bok]

The Island_NT.zip right ?

ok, I've fixed that one.

I'll see where we stand on the .msi.

Bok

[DrkNexus]

I might be wrong in my basic assumption, but it seemed to me that circuts with fewer gates evolve more quickly to their 'optimal' solution. I was thinking that since the project right now is suffering from limited computational power because of the switch in servers etc if it might be a good idea to evolve smaller circuts until we regain some more users. It looks odd that our final results page indicates that we were steadily churning out results until November and then stopped cold.

[michaelgarvie]

Thanks for your comments. However finishing the RD53 run would be a very strong result to complete a series of experiments.

[HitchHiker]

Maybe now the time has come to send that email and notify others that things have changed? I suppose we gain more than a little bit of processing power that way. :cheers:
