Any help regarding multiple instances under Linode would be appreciated.


I had the same problem running PG from Linode hosts. Even though on the dashboard they have separate IPv4 addresses, PG seemed to see all of them as just 127.0.0.1 (but with varying IPv6 addresses). Some of them were recognized as separate Hosts, but most just rolled up under one instance. There wasn't any pattern that I saw, and it was difficult or impossible to tell which instances were which. I even started only one host per geographical data center, but PG didn't care and still lumped a lot of them together.

Not all of the WUs ended up as abandoned. I'd say less than 20%. And even then I still got credit for the completed task. But it resulted in the WU getting sent out to another PG user as well, so pretty inefficient from a project perspective.

Now, if you meant the PG infrastructure itself (and not the hosts that use it)...

...I think it would actually be best characterized as a traditional multi-tier client-server system. Not an XaaS variant.

As far as security risks, this is a pretty old post, but I haven't found anything else. The BOINC client does literally download binary executables to your local host, so you are implicitly trusting the project to a) not be malicious, b) not be unwittingly compromised themselves and have their binaries secretly infected with malware.

As the link above notes, you can sandbox BOINC using VirtualBox, which adds a security layer. But not every project supports that (PG doesn't, for instance).

Mostly IaaS. I've used Vultr (of course), AWS EC2, Azure, Google Cloud Compute, DigitalOcean, Linode, and (when they were still around) Rackspace Cloud Servers and HP Public Cloud.

The Science Cloud would be considered SaaS.

I think the security risks would be limited to the possible theft or unauthorized use of whatever payment source you've attached to the service. Most, if not all, of the IaaS providers I listed above offer or require 2FA on your account, so someone can't impersonate you and run up a bunch of cloud charges.

I can't really think of any way a potential intruder could leverage your cloud compute nodes to then penetrate back into your own local network. And if they break into your cloud instances, so what? It's literally just a bunch of numbers. I guess the worst possible scenario would be an unscrupulous rival PG User hacks into your cloud compute nodes and switches the UserID to his own so that he gets your credit. But that seems highly unlikely, and also not too terribly damaging.

So I also finally tried to upgrade to Win10, but my ASUS P5Q mobo isn't compatible. I got the OS to install, but it was all kinds of janky. So I'm reverting back to Win7 until I can scrap the whole thing.

Ultimately the new 1.0.3 version also lowered my times to something moderately respectable, so I'll limp along for now.

The 2 people immediately behind me have stopped progressing in the challenge statistics for about 10 hours now. Gelly powered past me in the last day and then just stopped. I am going to be very unimpressed if bunkering is going on.

I think Gelly has been utilizing TSN instances. Would be pretty tough to bunker those. May have just moved on to other projects already?

Time to get a decent board - I knew should have sent this one back the second I saw they'd made it 1cm shorter than standard atx. Anyone want to buy a crappy asrock motherboard?

They don't call is ass rock for nothing.

A quick success!

On 17 Dec 2020, 12:38:09 UTC, PDW found a prime 10841645805132531666786792405311319418846637043199917731150000^16384+1 (at bmin+5920). Congratulations!

As you can see, bmin is very small. If workunit wasn't timed out and aborted twice before PDW grabbed it, the prime could be found on the first day of the search.

Main goal of project is reached, first GFN-14 MEGA Prime found. Project will be active and new work will be loaded for 3 months since day of the start, until 05 March 2021.

Thank you :)

3rd time lucky, 1st and 2nd would be kicking themselves if they knew who they were.

That's also my 2021 goals met a year early :D


I tried to go back and check, but I don't think it was me. I only see one WU in Error state for me, from Dec 5. It was finally completed by Robish, and it was very close to this prime:
10841645805132531666786792405311319418846637043199917731151866^16384+1
