AOGenMark 1.3.0: Simple Multi-Core CPU Benchmark



AOGenMark



1 – AOGenMark: Overview

AOGenMark is a CPU benchmark with multi-core support. Multi-core support simply means the benchmark is multi-threaded. AOGenMark is not a new CPU benchmark: the first version has been released in 2006. AOGenMark is derived from a tool I used several years ago to compute per vertex ambient occlusion factor. I recently updated this benchmark utility for the HP Mini 210 review.

That said, AOGenMark is a command line tool with few parameters. In short, you can specify the number of threads (-t), the number of samples (-s) which are related to the heaviness of computations (the more the samples, the heavier the computations) and the thread affinity (-a). Thread affinity allows to stick a thread with a CPU (logical) core. For example, if you have two cores and you launch AOGenMark with 4 threads, thread 1 with run on core 1, thread 2 on core 2, thread 3 on core 1 and thread 4 on core 2.

Examples:

AOGenMark.exe -t 4 -s 8

Starts AOGenMark with 4 threads, 8 samples and no thread affinity.

AOGenMark.exe -t 8 -s 16 -a

Starts AOGenMark with 8 threads, 16 samples and thread affinity enabled.

How to bench a CPU with AOGenMark? It’s simple: the smaller the elapsed time to finish the bench, the faster the CPU. For recent multicore CPUs, the number of samples should be at least 16, the number of threads depending on the CPU: 8 threads for a Core i7 with HT enabled is a good idea.

AOGenMark and a 8-core CPU
Core i7 960 with hyperthreading running AOGenMark (params: 8 threads and 16 samples, no affinity)



That’s all for the parameters. I added in the zip file six .bat files for launching AOGenMark with 1, 2, 4, 8, 16 and 24 threads, 16 samples and no thread affinity. From my tests, it’s better to let the thread management to Windows.

3 – AOGenMark: Scores

Here are some scores. And recall that the smaller the elapsed time to finish the bench, the faster the CPU.

Parameters: 8 threads, 16 samples, thread affinity OFF

97.104 ms – Core X9650 @ 3.0GHz
51.184 ms – Core i7 960 @ 3.2GHz

Parameters: 4 threads, 16 samples, thread affinity OFF

96.261 ms – Core X9650 @ 3.0GHz
74.366 ms – Core i7 960 @ 3.2GHz

Parameters: 4 threads, 8 samples, thread affinity OFF

270.676 ms – N550 @ 1.5GHz
47.961 ms – Core X9650 @ 3.0GHz


4 – AOGenMark: Under the hood

And for the curious, here is the algorithm behing AOGenMark:

// Part 1: Slowest part of the algorithm.
for each face in a mesh do
  for each non-normalized vector in the pool
    Do a dot product between the vector and the normal face
      if dot >= 0.0 then
        Normalize vector and form the ray to cast
	for each face in a mesh do
	  Do a triangle-ray intersection test
	  if intersection then
	    store intersection data in a buffer
	    break;

// Part 2: Fastest part of the algorithm. 
// It's like computing mesh normals.
compute occlusion data for each vertex of the mesh

    Q6600 3.0 (4 threads ,16 samples) 4 cores , win7 x64 sp1
    result : 143708 ms

    thank´s

    8 threads 16 samples = 42.440
    4 threads 16 samples = 59.771

    Intel i2600.

    So this does use the HT parts of the cores, saving about 17 seconds.

    @Stefan: very curious! I’ll check how the number of cores are read, it’s an old piece of code…

    I tried running this on my 3 core Phenom II system and it keeps stopping at the same point after doing 2.5 lines of dots. It says it’s having a problem in the .dll file.

    so my Q9550 clocked to 3.8 performs the same as a I7 3.2ghz

    One problem with the benchmark it doesn’t run on triple or 6-cores. Program crashes.
