Are you still seeing upload issues?

Hmmm, looks like something weird was/is going on with our filesystem. I had to create/touch the file upload handler log file for one of our web servers. I'll talk to our sys admin about this to see what might have caused this.

Oh, I'm sorry, this is likely another issue. I'll take a look.

Some daemons crashed unexpectedly sometime this weekend. They are back up and running now. May have been a network glitch. Seems ok so far.

I just announced it to the lab so I'd expect some production jobs soon.

This is a different issue that is probably specific to your computer/boinc client.

I'll have to look into the possible consequences/negative impacts of enabling this feature. We'd prefer not to enable any bias though.

"Which leads to the long history of project struggles."

We've been up since late June with the new server front and back ends without any significant issues (knock on wood). This has been the first significant issue since and may or may not have been related to network and power instability here at the UW recently. The file locking logic in the upload handler started to fail for the majority of upload requests. We rebooted the web servers and filesystem but that didn't fix the issue. We had to modify the source code to comment out the file locking logic and rebuild the upload handler. This appears to have fixed the issue. The file locking logic is not necessary for our system and things appear to be back to normal.

On a positive note, I think our project has a long history of success including research from our lab being runner-up to Science magazine's breakthrough of 2016 for protein design, success in using co-evolution sequence data from meta-genomes to determine new protein structures at a cost significantly less than structural genomics initiatives, and designing/modeling small cyclic peptides with non-canonical amino acids (much of which was modeled on mobile android devices), and more.

I think we've resolved this issue. Please let us know if it persists.

The file locking logic in the upload handler was failing. We don't know what caused this; rebooting the filesystem didn't help. But rebuilding the upload handler after commenting out the locking logic did appear to fix the issue.

Just read this thread. Sorry. I'll alert the researcher.

These are great suggestions. I would post them on the BOINC development group threads from the BOINC web site.

Foldit has it's own code repository. The Rosetta core components are not updated as frequently as UI/game related features because I think it is a large task to merge the code.

The Rosetta Commons repository maintains the main source/scientific code. It is constantly being developed by the commons developers/scientists who are from institutions from all over the world (and the contributor base is growing).

When we update the R@h app, we use the latest commons code. I'm still waiting for our graphics app to be debugged but an update should hopefully come soon. A lot has changed including increased use of C++11 from the commons developers, some of which is not yet supported by Visual C++ and has to be ported, also new dependencies, and a migration away from Boost (related to increased C++11 use). Also, the "rosetta scripts" protocols will not be backwards compatible due to new XML format rules so the next app version will be a new app named "rosetta" which is appropriate :)

On the list of things to do. great idea. I'll remind/alert the lab about the memory issues. thanks.

This is my fault. I was asked by someone in the lab to increase the length limit on Robetta, our publicly available structure prediction server, so I did but since realized the memory issue. I've reverted the length limit until we can figure out a good approach to handle them. Sorry. There may still be some jobs left over. These are medically relevant targets.

I've been out for the past 2 weeks on a vacation without any network access for the last 5 days last week. The researcher has also been out of the lab from conferences and workshops and will be back in communication soon.

We've been waiting for a while for a researcher to fix his protocol for the graphics app. Just waiting on him for the update.

I think this issue is fixed now thanks to our sys admin, Luki.

Here are his notes on the fix:


"Monday 6/26 20:12:06 2017 | | [http] HTTP error: Peer certificate cannot be authenticated with given CA certificates

I've seen this problem when imperfect clients don't like the order of certificates provided by the server. Browsers don't seem to care. I rearranged them and the SSL test passes with flying colors, including the certificate chain verification (click the IP address for details): https://www.ssllabs.com/ssltest/analyze.html?d=boinc.bakerlab.org

OpenSSL is happy too"
