You're welcome! :)

I've been running this for about 10 days and no issues so far. Short wu's for the HMMPFam type -- est by BOINC at 26 min. Haven't seen the GARLI type yet. The HMMPFam wu's are running without a checkpoint and show no "progress" as this is a legacy science app adapted to BOINC. Very short deadlines though (72 hours?), so it may take a day or two for BOINC to adjust as you work this project into your queue. Apps for WIN, LINUX and MAC.

Pretty good communication from project manager via message boards.

[russkris]

Thanks for the update mate

[mewbysea]

The GARLI wu's are longer - ranging from 4-6 hours up to 9-10. The project extended the deadlines on these to 5 days, but they also run without checkpointing. I haven't seen any problems with that as I have BOINC set to retain all wu's in memory. Some team members using BOINC 5.10.13 have noticed that when they get one of the GARLI wu's it runs to completion rather than the usual 1-2 hour "rotation" stretch. I am still running BOINC 5.8.16 and these wu's behave normally for me, i.e. pause after an hour or two to let another project run.

The project has had occasional stretches of a a day or so without work, but in addition to the messages in the BOINC manager, the website keeps good track of this. Some of the lack of work is platform specific (Intel/Windows) as the project wants to ensure cross-platform validation. Work should increase as more types of the computations run under Lattice are ported to BOINC.

Continued strong interaction with the project on the forums. All in all, a good solid project -- recommend for the Vault.

[russkris]

We have the offical nod from the site admin to add the project to the Vault.

Post away people's, let us know how it runs etc

[russkris]

I really would like to get this project added...

Work is in batches, so there may be a bit of downtime from time-to-time

[mewbysea]

Just wanted to add an update. Both of the primary wu's for this project (HMMPfam and GARLI) now support checkpointing and show percent completed. Other wu types expected to be added to the mix this fall.


Anyone else out there in "Vault-land" tried this project? Seems like a very one-sided conversation here...:whistle:

[umccullough]

Team Haiku ran a few WUs a while back - it seemed pretty solid when I ran it.

I'll try to throw another machine or two at it this week.

[russkris]

Awesome...

[umccullough]

Solid project so far - the new GARLI application is a bit memory hungry, however - requires 300-400mb per unit.

I've noticed on my 1gb P4HT machine it will only do one at a time most often because there isn't enough memory for two simultaneously (get "Waiting for memory" status)

[vaio]

Only done a handful of units but seems perfectly stable and work availability/stats updating seems fine. :)

[russkris]

What project cat' would this fall into

[umccullough]

It runs various applications, but it appears they all revolve around DNA and protein research - so I would guess it's mostly Biological.

[cswchan]

Have run several WUs on this project... would like to see more WUs though... So far, it seems to be very stable. Might be a good addition to The Vault...

[fractal]

I have run a half dozen wu's through this project and it seems stable enough. I do have two concerns.

First is (from their project page)

Status - The project currently has no work available!second is from their system requirements thread

GARLI
Disk - 5M
RAM - 300-400M
CPU - several hourswhich can be a shock for people running 256 or 512 meg dualies.

All in all, it looks a good project though it would be better if it had regular work.

[glennpat]

It's sending out work units again. I have only done a few so far. Three were on a Linux box and it went fine, but did need to add some memory for the GARLI wu since I only had 512 meg on that box and it got bogged down. I just looked and the hmmpfam work unit peaked at 38 meg for it's use.

[fractal]

Work indeed is flowing as glennpat has reported. I have been running it over the weekend on several machines and it has been keeping my machines mostly busy.

I also found that they allow participants to limit the WU's they will accept permitting you to not take the 400 meg units if your hardware can not handle it.

All in all, it looks good.

December 19, 2007 Latest HMMPfam Runs
1534 batches of 276 jobs (workunits) x2 results/WU = a whopping 846,768 results to crunch! This should keep us all busy for a while. For more information on HMMPfam, look here (http://boinc.umiacs.umd.edu/research.php#protein).
December 18, 2007 The Lattice Project Makes The A-List
We are listed under Biology and Medicine, here: http://boinc.berkeley.edu/projects.php Also, see the news item on BOINC's front page (http://boinc.berkeley.edu/).

So, Biology and Medical it is. Plus lots of work as well.

I should add........got this email a couple of days ago:

Dear project participants:

We have recently made our code signing procedure more secure, but in so doing have needed to regenerate our code signing keys. Thus, if you had BOINC client(s) previously attached to the project, it seems you will need to detach/re-attach to the Lattice BOINC Project (http://boinc.umiacs.umd.edu/) in order to receive the new public key and successfully process new work. If I discover an easier mechanism, I will let you know. Until then, sorry for the inconvenience!

Sincerely,
Adam Bazinet

To opt out of future emails from Test Project, please edit your project preferences at http://boinc.umiacs.umd.edu/<wbr>/prefs.php?subset=project (http://boinc.umiacs.umd.edu//prefs.php?subset=project)

[fractal]

It seems to have fixed itself. I just checked the logs of one machine that has been on lattice for a while. It gave me "signature verification failure" on 12/19 followed by a bunch of "You may have an outdated code verification key" but it fixed itself on/by 12/21.

So, I don't know what he did, but I did not have to do anything to the machine and it is doing work.

[vaio]

So we're good to go at the vault Rusty..........sign it up :).........when the vault is back that is :p:D
