And the list of applications at https://setiathome.berkeley.edu/apps.php for main shows windows 8.24 to be on main.
I notice there isn't one for Linux there yet.

I don't know if Eric can apply the same command line fix to the executable and strip out the offending math optimization that he did to the Windows executable. Probably means at minimum he would need access to a Linux host which I don't think he has.

But it needs to be done since Linux hosts had the same issues with the 5700XT as the Windows ones. They were just not as visible since the number of Linux hosts is a fraction of the Windows hosts.

yeah I had the same thought. since Eric didn't recompile the app from scratch, he just pulled out the offending flags from the EXE. I'm not sure if it's possible to do that on the linux apps.

it's also possible that it might not even be necessary if the linux apps weren't built with those offending options to begin with. also on the linux side, it doesn't appear that AMD has even released a driver for linux that addresses this issue. their release notes don't even mention it like the Windows driver notes do.

can anyone post a Linux system that is having this problem? or post any linux system running this card? or is it just speculation that the same issue exists on linux? I'd like to see proof of it.

Half a dozen Einstein Linux users said the new drivers fixed the issues with the 5700 cards. They didn't need a new app, just new drivers.

So the new Application requirement looks like just a Seti thing.

it does indeed appear that fredi's system is/was having the problem on linux.

we need confirmation that the app was built with the bad options. it may not have been. but without a linux driver fix we can't know yet, we need to wait for the updated driver there. but the navi cards on Linux are incredibly scarce it seems and AMD might not be aware it's still an issue on Linux.

Since, according to his stats page fredi's Linux computer last contact was 2nd Jan then it is fairly safe to say that any GPU task returned were done on the old (8.22) app.

Looking at his Windows computer I would hazard a guess that it is the same hardware and he may have abandoned Linux (for now) - the Windows one came to life 15th Jan, and has (on the face of it) the same hardware spec as his Linux one (which had been around for less than a month).

well considering there is no 8.24 Linux app, yeah, he couldnt run anything other than the 8.22 app, even now. that's the whole topic at hand, whether the Linux app even needs updating. I was just looking for an example of a Linux host with this issue. We still need confirmation on if the Linux app needs a fix, or just a driver fix, or both. I still think that AMD is likely unaware that the problem is affecting Linux as well.

his windows system, does not appear to be processing any GPU work anyway.

Thanks for all the sleuthing. I ask because I'm planning a GPU purchase soon, though it sounds like the solution is in progress, either way. 5700 XT is of course what is being recommended, though I have my eye out for a Vega 56. I've been running ATi/AMD GPUs for SETI on Linux for about as long as it has been possible. I've had a lot of problems specifically with BOINC and especially SETI in the past several years, but I think we are on the upswing now. I'm *always* willing to test if that is helpful.

It is the same computer just dual booting because gaming turned out to not work very well on linux with 5700XT compared to my old GTX970.
Since Windows is still needed I installed Boinc on it also.. did I get it right that with new drivers and app version the computation should work with 5700XT card now?

Yes, all indications that the problem with the Navi cards and compute have been solved, (for Windows at least), with the new 8.24 AMD app and the latest Adrenalin 2020 Edition 20.1.2 Optional drivers.

+1, if you're staying on Windows, just update to the latest drivers and re-enable the GPU for processing. you should be sent the 8.24 app automatically.

that should be helpful. I was just looking at some of the bad systems and noticed a few were running anonymous platform and was thinking how they would get the new app if they stayed on it.

What about the World Community Grid program, which is just BONIC under a different name. Will this be updated as well?
As I'm using WCG program and not BOINC.

The BOINC platform code itself isn't affected, rather it's the client executable that BOINC (or WCG) downloads. Each project will have to recompile their client for the new drivers to set the required flag. BOINC will then download the new client automatically (unless they have an "anonymous" manually installed client lke the Lunatics one here.)

OK guys, let's make this an open Beta test.

Lunatics Installer v0.46 64-bit is available for testing.

For AMD/ATI: updated all apps to match the v8.24 stock release, with safety patch for RX 5700-series 'NAVI' GPUs. You must also upgrade to the Adrenalin 2020 Edition 20.1.2 Optional driver or later.

For NVidia: includes the 8.16 (opencl_nvidia_sah) application from Beta. This is intended as a temporary workround for drivers above 431.60 on Windows 10. If Microsoft has updated your drivers, or you have updated them yourself for gaming, use the default option 'MB8_win_x86_SSE3_OpenCL_NV_sah_r3486' (the original name for the same file). If you have older drivers, or if you are running a different version of Windows, go ahead and choose the 'SoG' app - with minor update to r3584.

The following link is for a Google Drive folder with two files: the main Installer, and a small configuration file. If you put both files in the same folder, and run the installer, it will run in 'test mode': it will extract the files you request and go through the installation process, but place the results into a separate test folder, leaving your main BOINC installation untouched.

If you want to perform the actual installation for real, simply delete the configuration file.

The installation process (which is unchanged) has proved itself over the years, so you shouldn't have any problems. The installer will locate your BOINC installation, stop it, install the new files, and restart it. The restart process sometimes fails: if that happens, just wait a few seconds after the installer has closed, and restart it manually. Or you may prefer to stop and then restart BOINC manually - either will do.

The installer is designed to preserve all SETI tasks in your cache, and run them with the new applications. This is the potentially difficult part, and I'd like to hear if there are any problems with disappearing caches. Because it's a possibility, and we're likely to go into a long maintenance outage within 24 hours, you may prefer to defer testing until SETI is back up and running.

Download from Lunatics v0.46 installer test, and enjoy.
