Where exactly did the 'no benchmark' idea come from?

Yes, 1548438 is almost for sure a VM. I looked at it and the values for both speeds were 1 billion ops/sec (which I think refers to GFLOPS, not GHz?) which from past experience I knew were the default (which you also found to be the case by looking at code). So I posted about it. Dark Angel ran the benchmarks (msg 71188) presumably after seeing my post, so now the speed values are what they are.

I also have a discrepancy in speeds on the same system but not as extreme. Floating point values on WIndows10: 5.23, WSL2 Ubuntu22.04: 6.66, not sure why either.

Hang on a moment - this thread is getting very muddled. Where did we get the idea that benchmarks hadn't run from? And whose account, which host, were we talking about at the time?

It seems to have started with AndreyOR's message 71185 - but that wasn't replying to a specific prior post, and the reference to 'you' is ambiguous.

I'm assuming that the reference was to Dark Angel, who is showing two computers on his account:

Linux host 1534740
Windows host 1548438 - further assumed to be running in a VM on the Linux machine, per message 71172

As I type now, both hosts are showing a normal 'measured speed' - Linux 3.14GHz, Windows 5.73GHz (*)

Where exactly did the 'no benchmark' idea come from?

* the difference in speed between the two instances is itself interesting, but for another thread.

No need to assume I have said plainly, my Windows 10 host is running in a VM. It has 16GB of RAM allocated and 4 CPU cores.
The host machine is my Linux box.
Further, I have manually elevated the CPDN tasks in the Windows VM to run at "high" priority. The VM itself is running with a nice of 0 while native Linux tasks will get a nice of 19 the same as any other Boinc task.

I don't know where that 5.73GHz figure came from, the Windows machine reads that it is running at 3.7GHz, the base clock of the CPU, and while I have adaptive clocking enabled I do not overclock my hardware. It just wears things out too fast for my liking.

My understanding is the benchmarks are the old Whetstone (floating point) and Dhrystone (integer) benchmarks. The units of measure aren't GHz, just number of operations per second, in modern CPUs it'd be billions. If you look at your system on the website, it'll just say 5.73 billion ops/sec. Those values aren't related to CPU speed, 3.7GHz in your case. The use of GHz was likely by mistake and it's caused some confusion.

Yes, that was me over-simplifying things when trying to cram too much into one post.

Hardware and operating system tools - chip specs, motherboard, BIOS, thermal limits etc. - will probably work in GHz: applications like BOINC are more likely to report in GFlops.
