Hello,

you have to copy the needed libs into your library folder (for me /lib64).
then create a link:
e.g.:
lrwxrwxrwx 1 root root 21 29. Dez 23:46 libcudart.so.12 -> libcudart.so.12.0.107
lrwxrwxrwx 1 root root 21 29. Dez 23:52 libcudart.so.12.0 -> libcudart.so.12.0.107
-rwxr-xr-x 1 root root 675168 29. Dez 23:45 libcudart.so.12.0.107

after this is done mfactc.exe can execute the self test:

The app must be static not dynamic which I have got.

Iam still trying to optimize the plan_class for cuda apps. There is a backward compatibility in drivers and cuda toolkit, so the latest change for Compute Capability 3.0-7.5 should only getting work with cuda100 apps. cuda110 will be deprecated soon, cant see a difference. Still observing any errors and sending out new work.

Can you change the mfaktc.ini configuration? GPU Sieve Size is set to 64, but the version supports up to 2047. There is quite a bit of performance to be gained with that change.

Not to mention the godawful coil whine my 4090 produces with this low amount.

Thx for the hint, I have updated a new app version with the latest ini file, also used a very old file from yesterday as the wrapper.

And thx for compiling the app, its working without the dll files.

Sweet!

The DLL insanity was a real pain if you did not have the toolkit installed.

Message 8650 - Posted: 15 Jan 2023, 0:28:30 UTC

rebirther, I noticed during the last week that some of my computers are showing a predicted run-time for TF gpu tasks of 1 second. This causes the machines to download large numbers of tasks. Is there a way to adjust the predicted run-time?

This will only happening by new apps while the server needs some results back to calculate the real runtime, anyhow it doesnt use the stored runtimes from an older app version. I have asked the devs if there is another option to avoid this.

./mfaktc.exe: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./mfaktc.exe)

I have already asked the user to recompile the app with an older Glibc version, most of the hosts have still 2.31, for the time being you will get a mix of cuda120 and cuda111 apps, the problem hosts getting some errors with cuda120 but can run cuda111 app.

There is a new v21 app with glibc2.27 to avoid errors on older systems. Thx to DeleteNull for recompiling!

Dear all,

The Trial Factoring application doesn't run well on my GPU (AMD Radeon RX 7900 XTX, Ubuntu 22.04 x86_64). Completion percentage remains stuck at 0,01%, while ETA quickly goes up (several days) before I abort the task.

more stderr.txt 12:31:22 (1840): wrapper (7.16.26016): starting 12:31:22 (1840): wrapper (7.16.26016): starting 12:31:22 (1840): wrapper: running ./mfakto-x64 ()


What am I doing wrong ?

Best regards,

Samuel

Hello,

Sorry for the late reply.

I'm running BOINC headless, so no event log I'm afraid (I'm using boinctui).

I saved the "slot" directory of that failed task to my home directory though. Could there be some useful information in there ?

Best regards,

Samuel

The stderr.txt could help.

Hello @rebirther,

I already provided you with that information on September, 24th:

more stderr.txt 12:31:22 (1840): wrapper (7.16.26016): starting 12:31:22 (1840): wrapper (7.16.26016): starting 12:31:22 (1840): wrapper: running ./mfakto-x64 ()


There's nothing else in that file, I'm sorry.

Best regards,

Samuel

We need to run a selftest, nothing is right.

Copy the content of the mfakto.zip to a separate folder and run

./mfakto --st


or similar to the app name
