KLDIO broken
(this is a quick repost from Number Crunching)

A few hours ago Dave GPU returned the plaintext of KLDIO 90.
More info was posted in this forum thread

Please abort all the g3_kldio* workunits that haven't started yet, as they're not needed anymore.

New app: "Enigma Test", OpenCL and Linux tests
I'm going to add a new application which will be used to test new app versions and platforms/plan classes.

It will run it's own mini batches of test work and once the tests are done and finished with success, the test app / app version / platform will be reassigned to standard workunits.

Test app will have it's own checkbox in project preferences and it will be reset to off for everyone on each app version change.

First app versions that will be tested soon are:
- OpenCL/ATI version of GPU app.
- Linux version of CUDA app.

I'm not sure when it will be released but my early estimate is somewhere around end of this week.

Enigma Cuda 1.07
CUDA app version changed to 1.07 for both Windows x86 and x86_64.
I have removed the plan_classes "cuda" and "cuda23" because the app required compute capability 2.1+ cards & I haven't seen even a single task completed with success on "cuda23" plan_class.

The new version was recompiled to allow compute capability 2.0 cards:
GeForce GTX 590, GeForce GTX 580, GeForce GTX 570, GeForce GTX 480, GeForce GTX 470, GeForce GTX 465, GeForce GTX 480M (source: https://en.wikipedia.org/wiki/CUDA)
so in theory anything from Fermi up should work.

The CUDA app requires Visual Studio 2015 c++ redistributable package installed to run.

GPU app
As some of you may have already noticed, there is a GPU version of Enigma software available for testing. It requires nvidia GPU, and probably will run on anything that supports CUDA, I have tested it myself on a couple of low end cards and it ran just fine, except that the system was lagging and WU runtime was very long.

Until yesterday it required app_info to run, this was changed and currently it will be sent to any host that has 'beta work' allowed in preferences. I have reset the beta flag to off for everyone.

The app is marked as "beta" because there are still some issues both on the client and server side. Also, currently the GPU app runs via wrapper and that causes some issues, for example, this page says that interrupting GPU app while it is running the kerney may cause system crash. This is worst case scenario and so far I haven't seen it myself, but I assume it's possible.

Other than that, if left untouched, the app runs smoothly. At this moment it'll only run on CUDA device #0.

Progress bar does not work with the current version of the wrapper, but it's not a high priority thing at this moment, as tasks are relativery short: from ~20 minutes on GTX1050 to around 3m30s on 1080Ti. The app uses internal checkpoints and will automatically resume from the last checkpoint if restarted.

Scheduled upgrades
The server requires BOINC server code upgrade to support GPU app,
Per-app credits, application selection and a couple of other things.

I have scheduled the upgrade for this weekend, the server will be stopped on saturday, in worst case it might even go completely offline for a couple of hours.

Web server moved to new location
Since May 1st my VPS (which is running the web server) was unreachable almost half of the time and it eventually died. The tech support was unable to fix the problem so I decided to move somewhere else.

The server now runs on Amazon Lightsail with a new IP address - 34.203.18.49

The reason why work generator is stopped
I have stopped the work generator because IMO it does not make sense to continue the batch that runs with the original ("naval") dictionary set, where upgraded dictionary sets have already failed with similar number of target restarts.

IMO it's better to try with another dictionary set and tweaked app.
Both cases, however, require major upgrades on the server side - for performance reasons, I have removed some of the functionalities it originally had and now I have to add them back. It's going to take 2-4 weeks because my job leaves me very little spare time. I'm also going to clean the database from any leftovers, there are still over 20k workunits in the db, probably most of them are broken WUs that accumulated over time (at some point there was a sudden failure of SSD drive where the database filesystem is located, it was replaced by RAID5 setup with the data restored from backup, but ~4500 workunits/results ended in messed up state). I'll wait a few days and then all the orphaned workunits / results will be removed.

Also, all future (larger) batches will be split into a group of smaller sub-batches. While the batch is running, the server requires access to all the results that were returned and if the database gets to big, performance suffers. It also makes creating 'offline' backups harder due to the amount of data in the db dump.

In a few days I'll post downloadable results from the previous batches in case anyone wants to take a look.

Recent changes in account creation
As everyone may have already noticed, the project has been heavily hit by spammers. For the last weeks I've been fighting with up to 10k registrations per day, mostly just empty accounts which were created for unknown reasons (very few of them actually posted anything on forums or created profile/spam team).
I've been looking into possible ways to filter out the spammers right where they start (registration) and after looking at a few of possible solutions, I made a patch for the BOINC server to use StopForumSpam databases. For now, the server does not allow access to registration script from any IP listed in SFS db and it also refuses to create account with email address which is blacklisted there. This immediately filtered out more than 99,9% of new accounts, the rest is reviewed manually and eventually spammers that slipped through registration are reported back to the SFS.

There is also a daemon scriptwhich runs in background, randomly picking account and checking it against the blacklists, all accounts registered with blacklisted email address will be gone sooner or later together with any team and/or profile they have created (the script works very slowly, checking one account every few minutes, as I dont want to stress the SFS API which is a great free service).
The script won't touch anyone who has any credits or even hosts attached, so legitimate accounts should be safe even if someone has their email blacklisted.

Work generator paused
Recently the work generator has been paused because the server needs extended database maintenance (there is a significant amount of workunits stuck in unknown state, which affect performance).
I'm also running data analysis on all the results returned so far, the process eats a lot of resources so probably the work generator will remain stopped until the data analysis is done.

Planned maintenance on April 18th
The company which is hosting part of my server (download mirror, domain and a few other things) announced that my VPS will be moved to another location (datacenter) on 18th of April.
The IP address is going to be changed so I think the server will be unavailable for at least couple of hours, maybe up to a day.

Server maintenance
Tomorrow (04.03.2013) around 08:00 GMT the server will go offline for 12-24 hours.
The reason for this is hardware replacement, the old server barely keeps up running under load and has serious performance issues.
The swap is going to take a while because I need to copy data from both old drives, I hope that 'dd' image will do the trick.

New M4 batch - U-534 P1030680
The work generator will be restarted today, running a new M4 batch on VROL NMKA naval message.
At first there will be only a short test batch to check the server backend, after the tests the server will resume in auto mode with lots of work.

It's also possible that the server will go down for a couple of hours during the next days; as the system hard drive needs to be replaced.

No work available
As probably everyone noticed, there is no work available for a long period of time.
Unfortunately it's not going to change soon, because I have to find a replacement server.
The old machine is not reliable anymore, it passes stress tests yet freezes randomly after couple of days (or even weeks sometimes) during normal operation, which is not acceptable.
The worst part however are the HDDs, only two still alive, one is damaged already while the other starts to suffer from old age (was online for over 3,5 years).

In current state the server barely keeps the website up, so any work has to wait until I'll get the new hardware setup, which is going to take a while.

Updated apps
Yesterday I released new app versions for Linux and Windows.
On Windows, very little was changed, mostly minor fixes around BOINC API code and checkpointing/progress calculations.
Linux version fixes all known/reported wrapper bugs (and hopefully didn't introduce new).

There is also a new platform supported by the server - armv5tel, however the platform-id returned by the client varies on those machines, so if the server says the platform is not supported, you need to submit the platform name (as returned by core client), preferably after veryfiying that the app works.

P.S. I'm looking for someone to build the updated wrapper for Mac.

Server issues
On 24 Dec one of the server's hard drives failed, as a result I had to set up a fresh system so I decided to switch to new OS version as well as the latest BOINC trunk, since the amount of work to do didn't change by much.
It took almost 2 days to get most of the things working again, but there are still some things broken/not working at all. Please report all anomalies, I'm trying to get rid of all bugs/glitches but it will definitely take some time, as the list is still long.

Enigma badges
Few months ago one of the participants proposed a set of graphical badges for the project, since then a couple of designs (which can be viewed here: http://www.boincatpoland.org/smf/enigmahome-78/propozycje-odznak-dla-enigmahome/) were made by BOINC@Poland members.
I'm going to implement the badges before the end of this year (or early 2012 in the worst case), next week I'll make a poll which will decide which one of the sets will be used, so there is still some time if anyone else would like to submit another set of icons.

Also I'd be glad to hear opinions on the amount of credits needed for badges, considering the fact that (at least for now) it's a project with with just one app.

Server down - power issues
Today morning the server went down unexpectedly most probably due to power failure. A bit later it was automatically restarted in disabled mode because at least one of the database tables needs to be repaired.
The server will be up again today, however it has to wait a couple of hours because I do not have access at this moment.

Server downtime
The server is back up after it's longest outage. Unfortunately I had no money to pay the hosting bills so after a while my account got disabled and the server became unreachable.

I also had hardware problems with the local part of the server, as a result minor part of the database was recovered after critical failure, it's not yet entirely fixed so most probably validator will mark some of the results as invalid. Since it's already late night here, I'll fix that tomorrow, together with the WUs marked as timeouts.
It's also possible that I'll be changing the server location, I'll post more info tomorrow.

Server down
The server is down since yesterday due to very bad weather conditions and local flood.

Around 17:30 local time the water level was extremely high, no one ever has seen it higher or even close.
As a result there are random and unexpected power outages, so I'll keep the server down for a while to prevent database damage.

Server downtime
During this weekend the server will be taken down for O/S upgrade.
The old distro (Debian 4) will be replaced by Debian 5 amd64, since the older version has a limited support and probably slows down the hardware a bit.
It's hard to estimate how long the upgrade process will take, but I'd say that 8-12 hours minimum, because I have to do a complete backup first, so in the worst case I'll be able to rollback everything to the previous state.

Temporarily out of work
The server is out of work, for two reasons: the M4 server is out of work, because the awgly keyspace is finished. Also, I was going to run one of the other known unbroken messages while waiting for Stefan Krah to update the M4 server, but unfortunately during the last few hours one of the BOINC server's hard drives failed. Luckily nothing seems to be damaged except one table which contains unimportant log data, but until I'll fully diagnose and fix the problem, I'm taking all the daemons offline. It's also possible that later today I'll shutdown the server to replace the drive.
