This code tries running an .exe on Linux! Can be done under WINE (emulator), but not native.

Please see the FAQ, you're missing the CUDA 10.1 toolkit and you need this specific version in order for it to work.

I'll upgrade the system to Ubuntu 19.10 and install the latest Nvidia, OpenCL and CUDA files

That's not something I can choose, it is an error that the code comes up with

What card do you have?

Error comes up using various AMD APUs (Athlon 5350 Radeon R3, Athlon A12-9800E Radeon R7)

no, not anymore, if I enable on server side you will see an option for this.

I just checked again, but it still shows what I pasted a few minutes ago

I think that is, in the prefs

No, GPU72 can be chosen, and you can choose to have other than the preferred apps when there is none of those you checked. The is NO option to run test apps.

How can I get those tasks?

You must enable "Run test applications"

That is NOT a setting on the account page

Same for Linux/NV.

18:37:48 (3505): wrapper (7.2.26012): starting
application ./mfaktc.exe missing

Seems to be running on the R VII in Windows.

Edit: FP16/32/64 calculations?

First 2 have completed in 549 and 559 seconds.

Trying to have an *.exe running under Linux? Are you even serious?

Posted 29 Feb 2020 by Dirk Broer

Everything on the server status page shows Ubuntu as the OS, why is there a Windows point of failure at all? Windows 10, is it a LTS build? I don't like running Win10 on my desktop, but I also play games that will not run on Linux.

How much work was lost? What was the cost of trusting MS?
Giving the hardware a pass may be wrong, but I'm assuming we're running on enterprise gear, that may be a false assumption on my part.

Ubuntu is the Guest (running in VMware under windows10) I need both systems. A VM can be moved to another place too.

Could you do it the other way around, make Windows the guest of the Ubuntu system?

I would hope Bok at Free-DC would be able to give you the delta values from the last good stats to what was lost.

Mine was 351,000 all on Riesel Base - short...

I have all values from the last export but dont know how to import.

Update:
missing credits updated manually

Any chance of getting the lost SRBase data restored too?
And please note that our subproject credits are still not re-adjusted, hopefully Bok has those too.

If I find a solution to import then yes otherwise no.

The total scores that you corrected are given in user.gz,
the sub-project scores that hopefully can be corrected too are given in user_work.gz. Bok of FreeDC has the data you need, I hope. He can show today what you lost yesterday per subproject on your usersubprojects page.

Posted 18 Apr 2016 by Dirk Broer

RaspberryPi has this http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0301h/index.html (section 1.5.9)

And the RaspberryPi just has to do with a ARMv6 CPU. BananaPi and others based upon the Allwinner A20 SOC do it with an ARMv7, which is more powerful.

In the meantime the Raspberry Pi 2 has come out, using an ARM Cortex-A7 with ARMv7 architecture/instruction set and that has been followed by the Raspberry Pi 3, using an ARM Cortex-A53 with ARMv8 architecture/instruction set. Biggest problem for the Raspberry as a crunching platform is the small amount of RAM: 1 GB.

Ever watched in the debugger whether an AMD CPU actually uses the AVX part of the code? the Intel compiler-made Assembly seeks a when running on a non-Intel CPU.

oh no - not again that ancient story. :(
even if this still would be the case - but of course you seem to be sure that intels compiler has been used for the app in use here...

Well, Mr. Frankhagen, just for you: the same Motherboard (ASUS AM1I-A), SOC (AMD Athlon 5350) and amount of memory (16GB), plain install of OS and BOINC, nothing further:
Under Windows 10
Under Linux
Look especially at the given integer performance....
How do you explain that, other than with AMD systems being artificially crippled by compilers and/or libraries favouring Intel?
An Intel CPU or SOC does no give this dramatical differences -in fact almost none at all.
