Hi,
ich programmiere eine Ameisensimulation mit OpenCL und OpenGL (+SFML).
Jetzt komme ich nicht weiter, OpenCL gibt mir auf meiner Nvidia Karte den OpenCl Fehler -6 (CL_OUT_OF_HOST_MEMORY) und auf meinem Intel Laptop -4 (CL_MEM_OBJECT_ALLOCATION_FAILURE ).
Es liegt an OpenCL. Wenn ich die Ameisen ca. 3 Sekunden simuliere kommt nur noch je nach System die oben genannten Fehler.
Danke für eure Hilfe !
