Hopefully this is going in the right place.
I'm not sure what's going on here.
This computer, from boinc's perspective, seems to be doing just fine. There are currently two Tasks that have been running for days and don't seem to be stalling. Did it just take CPD a while to figure out what would work with my machine?

In reading the faq I'm being told that the machine can be disconnected from the internet for prolonged periods. So this is confusing to me.
upload failure: <file_xfer_error>

I have it set to 3 cpus to prevent excessive ram usage. It does have 6 gb which in theory should be enough for the smaller tasks.

I just Want to make sure I'm actually contributing rather than wasting CPU cycles.
any help appreciated here. Is this normal?
thanks

The "Signal 11 received: Segment violation" is the key part of the error message, and just says that something went wrong, probably in the software. The "upload failure: <file_xfer_error>" usually just means that an expected file was absent (probably because the work unit failed).

So I don't see anything wrong with your machine. We all see error messages like that. Keep crunching. If you don't get success in three or four more work units, come back for help.

Some batches have higher frequency of Signal 11 errors, and some of those SAM25 batches in particular It's doubtful that it was due to a problem with your computer.

As an aside, what should I be looking for to know what batch and what length of wu I'm crunching out of curiosity?
I'm assuming for instance that sam50 is South America 50 km, but I just want to make sure.

Using the model name that you mentioned:
wah2_sam25_s3hj_200312_13_719_011512003_2_r1565019525_1.zip

200312 is the start year/month
13 is the number of months that it's intended to run
719 is the batch number, useful for quickly identifying a model type
2 is the number of attempts, starting with zero (0) (So the one that you had was on it's last chance.)

The 1 just before the ".zip" is the data file number that's trying to get back to the researchers.
Or, in this case, NOT.

That long list of file failures is just BOINC saying that it can't find them to upload them.
Which is because that model failed after 7 minutes, long before any useful amount of data could be created, and zipped up ready to return.

That's correct.

Some times here, just lots of people not being able to get a batch of models to run is "useful" information for the researchers.

There's a bunch of region map images that Iain Inglis posted in this thread.

Thank you! This is exactly what I was looking for.
I've actually written all of this down in case it happens again.

What WUs tend to run the longest, out of curiosity? Especially under Windows, since that is my primary.
thanks!

Usually anything with a 25 km resolution and the more model months, the longer it will take so a 25 month SAM25 or EU25 would take longer than a SAM50 or EU50 for the same number of model months.

Thanks! Much appreciated.
Getting a Lenovo x1 Extreme with the i7-8750H. That should be able to do some pretty nice work, hopefully. Pretty excited for it to arrive next week.
