1 year ago Hi @Jmedelli,
together with the graphics window a second console window will open in the background. Click to free the mouse, then Alt+Tab to the console window. This will show you error messages if something does not work. I strongly assume that your GT 210 1GB GPU has not enough VRAM for most of the sample setups as-is. But you can reduce resolution in the sample setups. If there is a line
const uint3 lbm_N = resolution(float3(..., ..., ...), 2000u);then the 2000u is how much VRAM the setup will use in MB. Reduce this to maybe 700MB; your operating system might occupy ~300MB already. You see this in the standard Benchmark already: Even though it only needs 880MB VRAM and your GPU has 1GB, it fails to run the kernel as the OS has some overhead, and reports an unphysically quick runtime, because the kernel is not executed at all.
So try with lower resolution.
Kind regards, Moritz

Hi Dr. Moritz, thank you for sharing your work. When I run the sample programs, it goes through compiling, opens the window, but it stays black, or it would sometimes show a picture which comes out frozen. The right lower area with Fps however runs, but it seems something is off with my computer not being able to show the picture. Do you know what could it be?
Not sure if it helps, but this is what I got for my benchmark test.
