It took me very little time to get all the files for the one work unit I just got.
I have a 75 Megabit/sec Internet connection with Verizon FiOS.

Yeah, it's better now...

Yesterday, when all the WUs hit, and all the starving Linux servers were fetching everything they could, it was pretty bad.

I think everyone's fed now, to within the bounds of the initial slug of work. And based on how long some people keep returning credit, probably plenty of extra days of WUs. Though if you're going to do that, benchmark first - otherwise it thinks the machine will take 100+ days to get WUs done on the default performance, and you won't get more than a full CPU set.

I've got my pair of 3900Xs up and running and loaded down, with my eDRAM 5775C finishing out some other stuff before it chews into the new stuff (I had it loaded down with Einstein WUs).

IIRC, a couple other people here have similar 3000 series Ryzens - I've handwavingly limited to 12 tasks, under the logic that even with 64MB of L3, they're still pretty cache hungry. But I don't have a good way to tell, on AMD, if I'm managing more throughout with 24 (at least on the machine with enough RAM for it). On Intel, the there's a performance counter utility that lets me monitor total instructions retired per unit time, which is throughput, so I can tune for that. But I've not found a good way to measure that on AMD/Linux yet.

//EDIT: Oh hey. Modprobe msr, have msr-tools installed, then 'rdmsr -a -x 0xC00000E9' should get you the retired instruction counts per core. I'll write a little wrapper for it here and I can benchmark throughput.

I got only one task, but I did not benchmark first. I last booted my machine about 8 days ago, so I surely did one then, but OTOH, no ClimatePrediction tasks were running.

My one task I got estimated a little over 8 days to run, which is what it normally takes.

I am now up to 2 hours executed and 8 days 3 hours estimated time to go.

I just ran the benchmarks and the estimated times to completion did not change, but maybe that is looked at that only once, when the process first begins.

That's about right. My new builds are showing "100 days" to completion. Far as I can tell, "performance stats" only get processed into estimated time at the task start - it doesn't update once they've been created. Not a problem, it doesn't impact actual performance, only estimates.

Mine are estimating just under 12 days each.
My estimate is: Who cares, I've got some more work at last. :)

And some good news.

@dave18874629 as @suzannerosier1 says we hope to have some windows work released soon for the new NZ25 region and we also have work in the pipeline to develop an EAS25 region that will also have work coming.

However I am willing to bet that the servers get emptied pretty quickly once these appear.

Aw yeah. Make the machines work for their pay! :D

I got my AMD instruction counter working, will clean it up a bit and stick it on Github soon. I'd like to figure out how to get DRAM read/write bandwidth while I'm in here...

They haven't updated the 32bit windows Boinc for 3.5+ years and the 32bit linux version for 7.5+ years. I guess they think if you are running older operating systems, you can download older versions of boinc and make do. The problem came about last fall due to the certificates being installed with older version of Windows boinc expiring. They came out with a new 64 bit version with a newer certificates list, but no new 32 bit version. They do have a certificates file to download at the top of this page: https://boinc.berkeley.edu/download_all.php if one is still running the older Windows versions.
I remember where I got this from now, I got the impression Boinc is (at least partially) still 32 bit because it fails to detect a GPU is over 4GB. The 64 bit projects that use the GPU can see all the VRAM though.

Cool! I have 90 CPU cores waiting here, they're all checking for work, but I don't know how often, I think it's once an hour unless they're busy with other projects, which is always. I have a small buffer though. [Engaging tickle mechanism]

And some good news.
And the bad news is that the three testing tasks have completed but the zips are not uploading. I have informed the project but still waiting for a reply. Most likely Andy just needs to kick something to restart it. Unlikely to delay the as yet unknown date of the main site Windows tasks by more than a day or two at the most.

Do you know the rough date of Windows tasks? Are we talking a week or a month?

Also, is the server status page accurate? It claims there are only 4 Linux users doing 4186 tasks!

That means only 4 Linux users have returned results in the last 24 hours (or something like that); it is not the number of (Linux) users working on work units.
My machine at the moment is working on three ClimatePrediction work units at the moment, 2 MilkyWay work units (one of which uses 4 processor cores),

But surely if there are 4186 in progress, more than 4 of you have contacted the server in the last day? Does it not include downloading and trickle ups?

That bit, at least, has been corrected in the forthcoming v7.20 release (preview available for testing - see BOINC message board).

There were earlier problems associated with the 64-bit SSL security libraries failing to run on some low-power Intel processors - that was corrected two or three years ago. I wonder if the WINE error could have been related to that one?

Previous practice was to upload the zips to a server located in the region under investigation - NZ, in this case. The kick might be better directed there...

Have you checked <http_debug> log flags to see what the exact problem is?

Not 100% sure but I am fairly certain it is only the number who have reported completed tasks. That is based on the dev site which uses the same server code and the numbers are low enough that I can be sure trickle ups and zips don't count in that number.

Edit: so none of the two most recent batches which will take about 9 days on my Ryzen will be near showing yet on that metric.

Usually Andy then has to contact them to tell them it needs kicking.

upload4 I posted on Trello board for batch a long extract from event log with http_debug, http_transfer_debug and file_xfer_debug all checked. Though Andy probably won't see that unless Sarah or the batch owner point him to it.

Edit: Have short circuited that bit and emailed Andy.

Edit3: Right now 05:45 in NZ. Might have to wait a bit before the machine gets kicked.

Edit2: Andy has emailed sysadmin for the relevant machine.

I now have three N216 work units running. IIRC, they trickle every 1/8 of the time through. This would mean that my first trickle should come about 24 hours after it started. In this case, the oldest of my three work units is about 16 hours in and is about 9% complete. It has been so long that I do not remember if this counts on the server page.
