Usually people test against lower-end CPU/IO, not high-end.
What are you wanting to see or prove by running your code on a higher end CPU ?
I'd rather be phishing!

The key thing for me is to calibrate a C snippet for modern CPU, e.g. Haswell.
I want to see what boost e.g. the Haswell's 4 ALUs can deliver in internal loops where every shift/rotate/multiplication matters.
My old Core 2 cannot give me the real picture.

Well I've got a 4770K right here. Maybe we can work something out.

Shift/rot still have a throughput of 2/cycle at best. Shifts by cl have become worse than they used to be, consider using "shlx" and friends.

Many thanks for your readiness to help.
One of the things that interests me is how FNV1A_farolito fares on i7 4th generation:
http://www.sanmayce.com/Fastest_Hash/index.html#farolito[^]
It has been a while (6 months) since my last play with FNV1A_farolito and I didn't put it in a bench package as other functions. Grrr, I'm not ready at the moment.
The other is my MEMMEM function, however I won't bother you with either, again I am not ready.
I will be happy if you are still willing to run my MEMMEM after I write Railgun_Swampshine package.
I am not in a hurry at all, I have been asking for half a year for such benchmarking and nobody cared, thanks again.

Now stop and think for a moment about throughput on that PC.
If you want an accurate benchmark, then you need to be the only active application on the machine. So once you are finished, the machine has to be cleared completely and reset back to a clean install condition before the next guy can start installing the stuff he (and he alone) needs to run his app.
Remotely. Which means he has to upload everything needed to the computer, slowing things more, and adding the fun of potential illegal software installation to the operators risk list...
It doesn't make a lot of sense economically for the PC owners, unless they charge a considerable amount for the service - which means they aren't going to get many users, because a small number of runs will equal the cost of purchase of the equipment in the first place!

You discouraged me ... a bit.
Speaking of profits I admit my dumminess.

That's right.
>which means they aren't going to get many users
No problema, there is no race for amounting users, few of them would suffice as long as they achieve their goals.
As for the fee, if a serious coder needs feedback he willingly would pay the tax instead of buying such PC, but it is not about money, rather for the idea.

I was listening to talk radio this morning and the monologue hit a sore point with me. They were talking about the words to songs like "Impossible dream" and "I did it my way". They were talking about making a difference and chasing the impossible dream.
This got me to thinking. I realized I've spent the last 25 or so years trying to find a company to work for that was willing to take risks and shoot for the moon. I realize that I haven't been able to find any. I haven't found a company like Edison that was willing to fail numerous times for that chance at one success. Willing to take a chance at shooting the moon, because it is too risky. We have no one that would be willing to try to land on the moon today.
And I realized that the reason there is no companies like this anymore, is that they only worry about the bottom line. They no longer care to challenge or make a real difference. Only make more money.
Am I wrong here? Are there companies that are willing to take these kind of risks? Maybe I'm just too cynical in my years.

Interesting, I never thought frogs had the intelligence to go insane or to get angry. They do have enough to sense danger and try to get away from it. (One will NOT sit quietly in a pot of water while you heat it up, instead it gets some urgency in its attempts to leave the pot.) Wow, I'd forgotten how cruel I could be in the name of science when I was a kid.
By the way, when they get out of the box, do they retain their insanity?

Heh? Just because he invented a cheap and safe(r) way to transport electricity than Edison's extremely expensive & dangerous method? I.e. AC current instead of Editon's DC requiring the "commutator" (basically what we now refer to as an inverter)? Or because he used fluorescent bulbs instead of incandescent (much more efficient & longer lasting)? Or perhaps because he thought up ways to produce all the different wavelengths of light - making things like medical x-rays possible? Or because he invented radio, wireless message transmission, etc. even before Marconi thought of sending a message without using wires? Or because he used radio to control a boat's electric motor and actuators for the steering (note the only thing he didn't invent in that sentence was the boat - even starting a whole new concept: robotics)? Or because he even had the audacity to invent a means to produce coherent light - Lasers? Or was it perhaps that he envisioned cheap limitless energy from the very bonds of matter - fission / fusion anyone?
So not that "mad" after-all ... just so far ahead of the rest of his peers that they assumed he styled himself some sort of wizard in comparison to them.
But this is truly the shape of things: Edison was BLAND in comparison to Tesla. Tesla was reaching for the moon, Edison hardly ventured out his door.

no mad as in his best friend was a talking piegeon who shot light beams from its eyes!
he was everything you said plus more a whole lot more, but he was also a few cents short of a dollar

It's always amusing to see people want to "change" history. I had a professor who seems to enjoy teaching that everything we learned as children was all wrong because now HE knew the real truth.
There are only 10 types of people in the world, those who understand binary and those who don't.
