Running Lumibench benchmarks for --width and --height greater than 128 #18

Closed anaitha2 closed 10 months ago

Hi, I wanted to run the benchmarks for scene 1, 18, and 21 with width and height high enough (512 maybe) to see the effects of Reflections, Shadows, and AO. However, I was not able to run the scene because the execution gets 'Killed' prematurely in the middle of 'Bind miss... ' execution. The benchmark seems to running perfectly fine for all scenes with 128, 128 dimensions though.

Hi! The program could possibly be prematurely killed due to memory constraints on your system.

If you're only looking for the output PPM to view the images, you can change the gpgpusim.config file to run a functional simulation only. This would be faster and require less RAM without the full performance simulation but still provide the PPM. You can do this by updating the -gpgpu_ptx_sim_mode flag to 1.

If this option does not work for you, I can also run the simulation on your behalf and provide you with the images. Thanks!
