As most will have probably be aware 2018 has brought about new security risks with our CPU's.
Operating systems are getting patches, cpu's will be getting new microcode etc to mitigate against the deviant behavior of some. To most user's this will be routine maintenance and will see no/little difference once patched.
However there are reports of certain specialist workloads appear to be heavily effected by these security fix's. It appears mostly applications that have many small writes & context switching such as compiling, databases and some image manipulation. Real-time applications and regular rendering appear to take a very small/insignificant hit if any. It's early stages, and will take a while for hardware vendors to release the patches.
I'm curious if and to what extent if any the performance impact of these patches may effect capturing reality.
Now a Shameless Bump.
If you wish to benchmark a data set before & after patching. It would be interesting if you can share your results and the status of your patching. As far as I am aware the OS patches will likely be forced upon us soon, however the bios/microcode may need to be manually applied when available. Each may have a different impact. (as of the time of this post few vendors have released the microcode patches, and maybe a few weeks until so.)
2) Choose your images and place them inside the newly created /CapturingRealityBenchmark/Images folder
For now I'd suggest a smaller collection that you know work. - None are currently included.
3) Run the benchmark.bat file
You will be asked to enter a identifier/nickname at the start, asked for a note if you wish, and to select the drive you use as the cache disk.
4) Sit back and relax
5) Once the benchmark has run it's course you can review the results in the results.txt file which should pop up automatically. And look similar to this.
Feedback on the benchmark tool itself is also appreciated. If you have any, positive or negative please post in this thread.
