Message 5259 - Posted: 17 Jun 2017, 23:38:25 UTC - in response to Message 5258.  

Hmm. Forcing to gpu only or to enigma cuda only resulted no tasks downloaded at all: "No tasks are available for Enigma Cuda". Same time other hosts that had enigma cuda disabled got message "Tasks for NVIDIA GPU are available, but your preferences are set to not accept them". And server status showed tasks available. Interesting, just telling my observations, not meaning anything negative.

That's because "results ready to send" counts all the results while the feeder queue size is much smaller (around 200 tasks) and at this moment tasks are picked up at random.
I will change the feeder settings tomorrow, it's already late night here and I'd prefer not to break anything before going to sleep.

EDIT: I have changed the way the feeder works, now it should always have some tasks when they're available.

Another test batch will be released today.
Old application won't work, I'll post links to the updated files before releasing workunits.

EDIT: I have updated links in the post above.
To run new tasks you have to download both the new wrapper and the updated version of the application and rename them to match filenames from app_info.
Running old version will fail all downloaded tasks.

3rd task with new versions failed:
Initialization failed: Error in file: C:\ProgramData\BOINC\slots\8\04unigr.cur
http://www.enigmaathome.net/result.php?resultid=269092513

Edit:
All g4-test72-2_* seem to fail run.
All g4-test72-1_* seem to fail validatation.

Edit2:
Not sure about failed validations. Might be because computation was paused.

Looks like the app can't read bigram dictionary (in the template it's called unigr but that's just logical name, it is replaced by the client with the file assigned to workunit).

I have disabled the batch that does not work (the one with scores set to 023), two others are still running.

Not sure why validator don't pass tasks even they are not paused. Only one of mine has passed validator so far.

Edit: Even that task was changed to invalid.
Edit2: I removed gpu version from app_info to not get more invalided tasks for this night.

I ran the new validator from command line manually.
The results that were initially validated and then suddenly changed to invalid, were marked as invalid by assimilator which does additional stages of validation. Everything should be fixed now.

I don't seem to be able get gpu tasks from server currently, so don't know if things work.

g4-test72-2 is broken for now. There are just a couple of leftovers in the queue, the entire batch is suspended.

EDIT: it seems that the latest update loads bigram but fails when loading unigram. I'm trying to find what's wrong.

app_info is not needed anymore, as both the x86 and x86-64 GPU apps are installed on the server.

Can app_info be used stillto allow compiler optimization of cpu only apps? I have updated to latest cuda binary from github.

Actually without app_info I didn't manage get tasks from server. Yes I am opted in to Run test applications.

Also latest cuda app from github resulted computation errors "Initialization failed: Error in file: C:\ProgramData\BOINC\slots\8\04unigr.cur" g4-test72-5_1 task. Switching to earlier "1.05" app seems to work.

There were some unexpected server problems, everything seems to be fixed now.
Large scale batch of workunits is coming soon.

You can use app info as long as you want, just take a look at this thread every now and then to eventually update files as needed.

Looks like the wrapper is unable to start the app.
Try to run the main executable from command line and check for any error messages.

There are some of the test tasks available every now and then.
Large batch was scheduled for today but since I had some issues with the server, it has to wait until tomorrow morning (which is just a couple of hours from now, as it's already late here).
