The literal Chinese name says it all: "Fake Mountain". The stones evoke the feeling of the beautiful rock mountains of China.
The term "奇石假山" (qi2 shi2 jia3 shan1, lit. "weird shaped stone fake mountain") is also used, almost as a synonym by many people, since the stones are often chose in interesting shapes. Choosing the right stone is basically an art form in itself.
The stones used are generally limestone, which as a sedimentary rock is weaker, and more likely to be eroded into interesting shapes.

Had hardware acceleration in mind from the very start, and for a long time that has meant GPU acceleration.

The interface is a bit annoying, but the tool is really cool.
100 cycles of matrixprod:
stress-ng -c1 --cpu-ops 100 --cpu-method matrixprod
man stress-ng gives the list of possible --cpu-method. It documents matrixprod as:
matrix product of two 128 × 128 matrices of double floats. Testing on 64 bit x86 hardware shows that this is provides a good mix of memory, cache and floating point operations and is probably the best CPU method to use to make a CPU run hot.
If you don't specify the --cpu-method it apparently loops through every method one by one.
Limit time to 1s instead of limiting cycles:
stress-ng -c1 -t1 --cpu-method matrixprod
