我一直在尝试使用此GPU库Rootbeer,我已经运行了演示,并且运行良好,然后我尝试运行我的代码,并且在此代码段的第二行(Rootbeer rootbeer = new Rootbeer();)中,我得到了错误(请参阅最后一节)。

    // This sesction is within a JSlider change event.
    int val = sldBrightness.getValue();
    List<Kernel> jobs = new ArrayList<Kernel>();
    jobs.add(new Brightness(val));
    Rootbeer rootbeer = new Rootbeer();
    rootbeer.runAll(jobs);


这是我正在运行的课程:

package pocketshop.graphics.adjustments;

import edu.syr.pcpratts.rootbeer.runtime.Kernel;
import java.awt.image.BufferedImage;
import pocketshop.Canvas;
import pocketshop.graphics.Colors;
import pocketshop.graphics.Preview;

public class Brightness implements Kernel {

    protected int amount = 0;
    protected int width, height;
    int[] pixels; // = new int[width * height];

    public void amount(int amount) {
        this.amount = amount;
    }

    public Brightness(int amount) {
        this.amount = amount;
        width = Canvas.image.getWidth();
        height = Canvas.image.getHeight();
        pixels = new int[width * height];
        Canvas.image.getRGB(0, 0, width, height, pixels, 0, width);
    }

    public void setImage() {
        BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
        img.setRGB(0, 0, width, height, pixels, 0, width);
        Preview.setImage(img);
    }

    @Override
    public void gpuMethod() {
        int[] pixels = this.pixels;
        for (int i = 0; i < pixels.length; i++) {
            int pixel = pixels[i];
            int red = Colors.red(pixel);
            int green = Colors.green(pixel);
            int blue = Colors.blue(pixel);

            red += amount;
            if (red > 255) {
                red = 255;
            } else if (red < 0) {
                red = 0;
            }

            green += amount;
            if (green > 255) {
                green = 255;
            } else if (green < 0) {
                green = 0;
            }

            blue += amount;
            if (blue > 255) {
                blue = 255;
            } else if (blue < 0) {
                blue = 0;
            }
            pixels[i] = Colors.rgba(red, green, blue);
        }
    }
}


这是输出错误。我真的很困惑为什么它显示Caused by: edu.syr.pcpratts.rootbeer.runtime2.cuda.CudaErrorException: CUDA_ERROR_OUT_OF_MEMORY: gpuHandlesMemory memory allocation failed

最佳答案

尝试编辑文件:/.rootbeer/config

将reserve_mem值更改为更大的数字。

然后可以通过电子邮件将以下命令的结果发送给我:
$ java -jar Rootbeer.jar -printdeviceinfo
