All very good questions that could explain why some people are more susceptible than others. It shows the huge amount of work that has already been done. It will undoubtedly take years to process it all.

Very nice. I hope we can make a contribution, if some researcher can be found to make use of it.

Posted 10 Apr 2020 by Jim1348
Regardless of how it turns out, you have my thanks and, I'm sure, everyone else's.

Yes, certainly. Most projects I have seen get maybe a 15X - 20X speedup with a GPU.
But TN-Grid had better start planning for more work. This will keep them busy.

We just submitted a project to answer a governmental call (COVID-19 related), among other things we asked for a server, hoping to get some money for it.

I was just thinking that this is like Sputnik, where everybody rushed into science and engineering (my masters degree was paid for by the government).
You will have more resources than you know what to do with before long.

How about expanding the 400 proteins involved in SARS-CoV-2 processing and replication???

That is a great article. If expanding the 400 proteins would do them any good, I am all for it and can put more machines on it. (The experts will have to decide if it is relevant.)

I see that Trento is right on the edge of the quarantine zone.

I lived in the Friuli for a couple of years and am familiar with the area.
Best of luck to them all.

Posted 1 Mar 2020 by Jim1348
I've just installed my new AMD Ryzen 9 3950X on my PC. 32 threads ready to run TN-Grid WUs 😁

That could be fun. It looks like they are doing 10,500 seconds on Win10.
On my Ryzen 2700, I am doing about 13,500 seconds on Ubuntu 18.04.

I run the project all the time anyway, so there is not much more to boost. But if they really want a boost, they just need to get listed in the BOINC Manager.

I know, they do not want to exceed their server capacity and run dry, but that is a problem for the crunchers. They will merely complain about it. But it would help the science, would it not?
9) Message boards : Number crunching : Help with invalid tasks and computation errors? (Message 1673)
Posted 21 Jan 2020 by Jim1348
3 failed (and errored) tasks so far on a Ryzen 7 1800x, running Windows 10.

It could be the segfault error. I see them on my Ryzen 1700 occasionally, but not on my Ryzen 2700. (And my Ryzen 1700 is one of the "fixed" versions, produced after they introduced the fix.)

We are here to help. Students can come up with the most creative ideas. Give it a try.
11) Message boards : Number crunching : Processing time: 1 WU vs 16 WU (Message 1635)
Posted 12 Nov 2019 by Jim1348
Running a single WU took 8,151 seconds to be completed.
Running 16 WUs together takes 12,500 seconds to complete a WU.

If that single work unit was the only thing you were running, then it was running effectively on its own core. The 16 WUs were running on virtual cores (two per real core).
So that is the difference you expect between a full core and a virtual core.
12) Message boards : Number crunching : sse2 vs avx (Message 1627)
Posted 30 Oct 2019 by Jim1348
Now, I have a new CPU that would be faster with the avx version but my machine will not get that version, because the old CPU was slower on avx.

If you are referring to your Ryzen 3600, it will probably be faster with the fma version. That is what both my Ryzen 2600s end up with, though they are on Ubuntu.

PS - The difference is very small anyway, almost not worth the selection process.
13) Message boards : Number crunching : [error] no project URL in task state file (Message 1619)

I don't see any other problems. Everything is still running OK. Thanks.

Posted 17 Oct 2019 by Jim1348
I just rebooted my Ubuntu machine, and saw this error message in the log. But everything seems to be running OK (TN-Grid is the only project on this machine).
15) Message boards : Number crunching : Validation inconclusive. (Message 1594)
Posted 10 Jul 2019 by Jim1348
It happens. I currently have one validation inconclusive with an Intel machine (I am on a Ryzen). But we both have a large number of valids, and no invalids.

So I think the validator gets a little particular at times with different chips.

Posted 9 Jun 2019 by Jim1348
Probably the best way to get known is just to list TN-Grid in the BOINC projects list. I hope they have taken care of that for the next BOINC release. Otherwise, it will be an uphill struggle.

A GPU version would do it. There are volunteers around on the various projects who may have the expertise to do it, if they know about it.

Yes, I just picked up a couple more. We are back in business.

I will be out of work shortly. Is this being looked into?

Posted 9 Apr 2019 by Jim1348
I don't understand the science, but you seem to have found one of the better biomedical applications for BOINC.
It appears to have wide applicability, and is the type of thing that no single company would do. It benefits from public volunteer participation.

I think you need to un-hide your computer.
