我一直在嘗試使用這個GPU庫Rootbeer我已經運行了演示程序，並且它們運行正常，然後嘗試運行我的代碼，並在此代碼段的第二行到最後一行（Rootbeer rootbeer = new Rootbeer();）上，我收到一個錯誤（參見上一節）。Rootbeer GPU CUDA_ERROR_OUT_OF_MEMORY
// 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);
這裏是我運行類：
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);
}
}
}
這裏是輸出錯誤。我真的難倒，爲什麼這正顯示出編輯的文件Caused by: edu.syr.pcpratts.rootbeer.runtime2.cuda.CudaErrorException: CUDA_ERROR_OUT_OF_MEMORY: gpuHandlesMemory memory allocation failed

什麼是你的GPU？你的代碼在GPU上分配了多少內存？ – ahmad
我有一個evga GeForce 9500 GT。有了rootbeer，我不知道如何在GPU上分配內存，但沒有顯示如何。這裏是一個例子：https：//github.com/pcpratts/rootbeer1/tree/master/examples/ArraySumApp/src/rootbeer/examples/arraysum –
嗨，你可以看看下面的URL有關rootbeer ，並給我一些支持？ - http://stackoverflow.com/questions/22597183/unable-to-cast-a-class-error –
