Hello Jacob,

I know about this problem, some workunits hang when calculating 10th pole and hang with never ending cycle (100% CPU usage). Now I'm waiting for Visual Studio 2013 to debug nvidia code. I have one workunit prepared for debug with this problem. This bug is very often on RTX cards.

My new RTX2080 is somewhere between me and eshop. I will inspect optimal coverage and setup for blocks/cores next week.

AMD powered miracles, nothing less :-D


So it's ok :-)

Compiler never brings any speedup except 32->64 bit version without SSE,AVX,FMA.

Might have to wait for some more WUs to complete, but so far it doesn't seem like an improvement over SSE3.


And what do you expect in terms of speed of an app?

New NVidia card brings new Compute capability (CC=6.1) so we need upgrade our application.

I will look into this problem today.

Go to your accoount home on website, then click on Asteroids@home preferences, click on Edit preferences and uncheck Use NVIDIA GPU - click Update preferences.

Wait or do project update in boinc manager on your pc.

I have focused on FMA4 app for new intel CPU's.

I will look on GPU apps with 9xx cards, but I have no timeline for now.

Happy crunching.

Not now. I will check grid dimensions for 9xx cards. Actual CUDA app was built before 9xxx had been released.

Sorry guys. No free time.

There is absolutely no difference in speed between sse2 and ss3 apps.

Could be correct say that highly optimized (double precision) apps do not benefit by the HT, while less optimized benefit more by the HT ?


For double precision: yes.

Did you restart boinc client?

or

Did you place app_info in correct location?

or

Is the real name of file app_info.xml or app_info.xml.txt (win nightmare)?

Posted 6 May 2015 by Profile HA-SOFT, s.r.o.

why HT off, performs better with avx ?


Because number of double precision units match number of physical cores.

No problem with periodic outage every day, I think.

Work buffer in boinc should be enough to live with it.

If it's option 2 is there a way to force a 1.1 CUDA card to run units?

That should have said "1.1 CC card" but can't edit/delete the message.


We need double precision floating point instructions and CC 1.1 do not support them.

As I know our database is constantly overloaded. Kyong is planing second server for mysql db, but this may take a time (and money).

Stay tuned and happy crunching

I think it's one raid5 volume with 7 disks.

First, we are very sorry for this situation.

Admin of Asteroids@home (Kyong) went on vacation. He will be back on Sunday 17.8.

Big thanks for your patience.

We have now two volunteers who try to make OpenCL app for AMD cards. Next I'm so busy at work for now. If both of them failed to do OpenCL app, I will do one.

Any progress in sight?


Sorry guys ... I'm still very busy at work. Meanwhile I made success at court of law and I can finally spent my free time with my son.
