1) Message boards : News : Batch plan (Message 4264) Posted 11 days ago by k29000 Post: I think I saw a small uptick of sf7 DS16x12 recently for a month or two. Curious if that was temporarily some Gerasim happening or if some work units was released in through numberfields
2) Message boards : Number crunching : Gerasim is not working (Message 4238) Posted 18 Feb 2026 by k29000 Post: The schannel certifiicate disabled message is not a server-side setting. It controls client side behaviour to certificate requests if you wish to see how the client behaves with it enabled, you can toggle it on with: curl -I -v --ssl-auto-client-cert https://gerasim.boinc.ru Earlier I agreed that deleting all client certificates works. But it is only a workaround and not the cause of the problem. The server shouldnt be asking the browser to launch the certificate prompt when client certs are available. IIS is sending an optional Certificate Request which is what I show in the video. It should not be doing that. Did you check the IIS setting I mentioned in an earlier message?
3) Message boards : Number crunching : Gerasim is not working (Message 4236) Posted 18 Feb 2026 by k29000 Post: k29000 I have one more request for you: Please show the output of the command: curl -I https://gerasim.boinc.ru (run from cmd, no need to elevate privileges) * Connection #0 to host gerasim.boinc.ru:443 left intact [/code]Phrase at the top: schannel: disabled automatic use of client certificate Seems to refute your last assumption (if I understand correctly). My output is the same as yours. The schannel message means Schannel will not choose a client certificate automatically from the Windows certificate store if it is forced to supply one. It will require manual selection or approval. You can change that setting. Disabled is the default. curl doesn't help us understand whether the server is requesting a certificate or not unfortunately. It also doesnt show us how strict the server is in the cases where one isn't supplied. curl is not verbose enough. Connections in curl will work just fine, like web browsers after the first request or when the client has no certificates, because the server seems to be giving the opportunity for a client certificate to be optionally supplied, not requiring it. I dusted off my Wireshark mental cobwebs because the only way we can see whats happening is to look at the packets for the handshake. At first when I looked, none of the packets showed any Certificate Request as part of the handshake. I then found a very old deleted blog post that explained that the way IIS implements client certificate requests, if it is configured to do so, is an initial handshake establishes an encrypted TLS connection, then the certificate request will happen in an encrypted channel, then the handshake will be renegotiated. For reference, in case I need to dig this up again: https://web.archive.org/web/20160111233743/http://blogs.technet.com/b/nettracer/archive/2013/12/30/how-it-works-on-the-wire-iis-http-client-certificate-authentication.aspx So then I configured wireshark to decrypt the traffic after establishing the first handshake and I was able to find the CertificateRequest. Here is a video. This one I am talking, so make sure to have audio. https://www.dropbox.com/scl/fi/zxg4dh54gpdmt1of12k5t/Gerasim-handshake-traffic.mp4?rlkey=hbls52i8mj8siv7swb4gui6v1&st=r1nzfk52&dl=0
4) Message boards : Number crunching : Gerasim is not working (Message 4229) Posted 17 Feb 2026 by k29000 Post: Yes. I have to delete all such certificates in the popoup not just myphone to get it to work. Browsers only show the certificate selection UI when they have valid candidate client certificates to offer. After seeing that behavior I read up on why this happens. The issue is caused by IIS configured to send a TLS CertificateRequest before the handshake. Once a connection has been established for the first time for a browser, IIS doesn't reissue that request. Also if the browser has no client certificates to offer, it doesn't launch the popup and sends back that it has no certificate to provide. Its likely that under SSL Settings in IIS, client certificate requests are set to "Accept". This is because clicking cancel gives you access to the website and deleting all client certificates also works. If it was set to "Require" it would block access entirely. Most websites would set this to Ignore, unless they have a valid reason to request a client cert, which is usually on corporate intranets with special authentication requirements. That's the most likely suspect causing the issue, but there could in theory be something else causing the server to issue the CertificateRequest
5) Message boards : Number crunching : Gerasim is not working (Message 4214) Posted 14 Feb 2026 by k29000 Post: I did further investigation. If you try to access "gerasim.boinc.ru" for the first time (so use a private window) in the URL it does the certificate prompt. If you cancel instead of selecting a certificate then the website loads fine. Thereafter it always works. The cross-device certificate is irrelevant since its asking the user to fallback on choosing a cert. The question is why is the prompt happening in the first place? Here is a video: https://www.dropbox.com/scl/fi/9xeat5awpgemhhwb6dhh3/gerasim-2.mp4?rlkey=4hastrxoul2au54rlfw255j3d&st=d3bu88gm&dl=0 I was able to replicate this on a few windows computers. Whatever self-signed certs are listed in the prompt seem to be irrelevant. It should not be launching this prompt at all.
6) Message boards : Number crunching : Gerasim is not working (Message 4210) Posted 12 Feb 2026 by k29000 Post: I have a request for k29000: Can you show the image with the certificate (where there's the phrase "Issued by: 72f79e24-a3ee-4b1b-9925-a3bf017745b2"), but the tab titled "Certification Path" ? P.S. Another thought I have: Our server uses a certificate with a 3072-bit key. And it's modern. But not all client programs support it right now. This might be the reason. Sure. https://www.dropbox.com/scl/fi/ouujsc3fsu0btf2k55fbn/certpath.png?rlkey=7h0mtlqce6h3wbjm1azh58n6g&st=s6bkbanp&dl=0

8) Message boards : Number crunching : Reduced credit per work unit (Message 4160) Posted 18 Jan 2026 by k29000 Post: Agreed, I can't contribute to this project any more but I still follow it because it was the only one I kind of got "invested" in because of the threads that would explain the research and the actual activity that happens on these boards. I also learned some things about GPU computation that i ended up applying to my own project while studying my masters degree

I need both of you to have visibility of the same discussion so you can chime in as needed, so the PM system on this forum is not going to work.

14) Message boards : Number crunching : Gerasim is not working (Message 4050) Posted 28 Oct 2025 by k29000 Post: ==== There is no progress on Gerasim's website. And there won't be until we reach some explicit (or implicit) agreements. on cooperation. Guys, without 2-3 qualified volunteers (constantly participating in the restoration). Situations like "Come on, come on, Russian Ivan, we'll help... sometime... later..." will no longer happen. ==== For All: Here's the first suggestion: Find a suitable place and create a topic "Gerasim Restoration" or something similar." That's an illogical pre-condition. Its clear at this point, given the time that's passed and the defensive message to someone simply asking for an update, that the problem can't be solved. No need for smoke and mirrors
15) Message boards : Number crunching : Please disable sending v3.0 (32-bit) app to 64-bit hosts (Message 3711) Posted 12 May 2024 by k29000 Post: I'm not sure why it's doing that. I double checked and I have the following parameter set in the config.xml: <prefer_primary_platform> 0\|1 </prefer_primary_platform> Send hosts app versions for their primary platform if one exists; e.g. if a host is 64-bit, don't send it a 32-bit CPU version if a 64-bit CPU version exists. Use this option only if you're sure that your 64-bit versions are faster than the 32-bit versions. In the past this was once caused by download errors: https://numberfields.asu.edu/NumberFields/forum_thread.php?id=483#3009 But if you suspect a bug turn on debugging and post to the boinc_dev mailinglist with a bug report.

For years I've been just running a spare computer with whatever happens when you run BOINC by default. CPU only, no GPUs. Wondering if there's anything I can do to get more performance out of it.
20) Message boards : News : 2021 Year in Review (Message 3212) Posted 20 Jan 2022 by k29000 Post: If search 6 is an order of magnitude larger than 3. And since 3 will have taken at least 1 year to complete (if we sum the number of days spent working on only field 3). This would imply search 6 will take at least 10 years to complete. Is the above logic correct?
