Min and the CPDN teams have designed weather@home East Asia experiments at 25 km resolution. weather@home = work for Windows hosts According to the "New work discussion - 2" thread at the CPDN message board, there is currently an issue with high failure rate of the w@h application under investigati...

Bump.

Thumbs up to Eric Driver.

The only reason for doing this is to keep the WUs consistent for the BOINC Pentathlon

One other admin could certainly have done the same, but did not, for whatever reason.
Edit half a day later: Or maybe he did after all.

The "click here" link reveals the secret how this was made possible with respect to PrimeGrid's server capacity: Note that we are NOT yet doing fast DC on GFN-15, Translation: Different from the bigger GFN subprojects, GFN-15 is not using the combination of normal "main tasks" and small cryptographi...

We are excited to share an update from the Smash Childhood Cancer team about the start of the new phase in their quest for curing cancer. The new target protein is MyoD1 (Myogenic Differentiation 1 protein) and one of its mutations, L122R. MyoD1 is a transcription factor that activates muscle-speci...

In short, ARP was suspended in January but is supposed to be resumed eventually. [Storage quota already exceeded, and data archival to tapes taking time and care] has now all been solved so there is room for continued activity by volunteers in the African Rainfall Project. We now have about 265 days...

See the other recent CPDN related threads in this News section: They are turning to models with much shorter task durations, but with big memory footprint and huge result files. Currently this is Linux only. Longer term they want to offer OS independent vboxwrapper based versions of this. (I.e., wit...

So far they emitted only about 7000 tasks, which are all assigned to hosts already (IOW, 0 tasks ready to send) and of which 1/3rd has already been completed. Their feeble upload server should survive such a small batch easily. But the announcement sounds like a bigger batch than that.

Whoa, about 1/3rd (edit: certainly less than half) of the task duration of the current oifs_43r3_ps batches, but almost the same result data size per task to upload? I should probably check their message board for whether they a) fixed their upload server¹, b) tripled its data throughput or added tw...

On January 19, the upload server filled its disk again. This time the reason is that the tape drive system went down, to which data were streamed off of the upload server. To make matters worse, when the tape drive system will be back up, for some unstated reason, it won't have enough space for the ...

Update from CPDN meeting 16/1/23 Upload http connections will be increased over the next 2 days back to the previous maximum of 300 simultaneous connections as most of the previous uploaded data has now been moved off. The 'grace period' for return of tasks has been changed from 'nothing' to 30 day...

The upload server outage continues — sort of — for another few days. And yes, the server remains seriously undersized. Hello All, Brief update on status. The upload server is back running and we are currently in the process of transferring ~24TB of built up project results from that system to the an...

I realize that the server has to catch up, but as poor as its performance is now, this will take a long while or may even never recover entirely. That's just my own pessimistic opinion, not fact, based on seeing server availability going down (and finally vanishing entirely) during the few hours ye...

It's not. xii5ku could upload some bits a few hours ago, but now 100% of the transfer attempts fail. parsnip could upload, but has an increasing rate of failed transfers too now and therefore shut everything off again (due to disk space constraints). I realize that the server has to catch up, but as...

Remove the dot before /home in the crontab line.

New ETA: Monday.

Based on their progress so far, I am not making any guess which Monday. :-|

The main reason (but not the only one) for this notice is this: If an OpenIFS task (of the current application version and workunit batches) is suspended to disk too often, it will take more disk space for its state files than allowed as per the corresponding workunit property. At that point, the bo...

A proposed fix is still in the making . Just out of a meeting with CPDN. They understand what the problem is. The upload server will be restarted but with reduced max http connections to keep it stable as best as possible. At some point very soon (today/tomorrow) they will move the upload server to ...

No. There certainly is no 3D acceleration hardware in it, and the kernel driver provides just a simple frame buffer device. The AST2510 has got an ARM CPU which runs the BMC firmware. But even if you rewrote that firmware so that you can run your own stuff on this CPU, this embedded computer would c...

Here is a 3.72 W video card: https://www.asrockrack.com/general/productdetail.asp?Model=TOMMY It is based on the ASPEED AST2510 chip, which is normally used as BMC. I am sure that its actual BMC functionality cannot be used via this add-in card, only the functionality as a VGA only video card remain...

Floppy disk drives are examples of block storage devices.
Perhaps they are migrating from 5.25" to 3.5" floppies now.

Glenn Carver wrote:The upload server has about 25Tb of storage,

OK, admittedly that'd be a *lot* of floppies.

According to the CPDN forum, they managed to revive the upload server today… only to have it fail again shortly thereafter. (Again no ssh access possible for the project admin.) Next try happens tomorrow. If it stays up, their network may be bottlenecked for a while when all the backlogged files co...

The upload server is down since >half a day ago. Take care that boinc's disk quota aren't reached. In theory, boinc will stop tasks. But if it doesn't work as designed, tasks would error out.

In this week so far: 88 valid, 0 errors.
Available CPUs/ RAM/ disk/ heating demand of the flat would allow me to do much more, but my Internet uplink doesn't.

Of my 20 + 2 newest completed tasks, the 20 on Epyc all had a peak working set size of 4.8 GB (varies by just a few MB), and the 2 on the Xeon E3 had a peak working set size of 4.4 GB (varying by just a few MB as well). Added in 12 minutes 35 seconds: PS: I watched the running tasks with htop for a ...
