Я собираюсь использоватьrootbeer1 в первый раз. Я в Windows 7 машина, 32-битная система с графическим процессором GForce 610. Я успешно установил CUDA 5.5 и выполнил примеры, чтобы убедиться, что он тоже работает нормально. Затем я установилrootbeer1 в соответствии с руководством, приведенным на странице GitHub.

Затем я загрузилRootbeer.jar в IDE NetBeans в качестве внешнего jar, скопировал и вставил пример кодаrootbeer который указан вВот, Одно изменение, которое я сделал, - это изменение импорта, при котором код в импорте страницы github

import edu.syr.pcpratts.rootbeer.runtime.Rootbeer;
import edu.syr.pcpratts.rootbeer.runtime.Kernel;

и мой код импортирует

import org.trifort.rootbeer.runtime.Rootbeer;
import org.trifort.rootbeer.runtime.Kernel;

Помимо этого я изменилсяrootbeer.runAll(jobs); вrootbeer.run(jobs); так какrootbeer.runAll(); не существует

Это потому, что NetBeans говоритpackage edu.syr.pcpratts.rootbeer.runtime.Rootbeer does not exists.

Ниже мой код

KeepMainTest.java

import java.util.ArrayList;
import java.util.List;
import org.trifort.rootbeer.runtime.Kernel;
import org.trifort.rootbeer.runtime.Rootbeer;

public class KeepMainTest {

  public static void main(String[] args){
    KeepMainTest app = new KeepMainTest();
    int[] array = new int[10];

    for(int i = 0; i < array.length; ++i){
      array[i] = i;
    }

    for(int i = 0; i < array.length; ++i){
      System.out.println("array["+i+"] = " + array[i]);
    }

    app.MultiplyArray(array, 5);

    for(int i = 0; i < array.length; ++i){
      System.out.println("array["+i+"] * 5 = " + array[i]);
    }
  }

  public void MultiplyArray(int[] array, int width){
    List<Kernel> jobs = new ArrayList<Kernel>();
    for(int i = 0; i < array.length; ++i){
      jobs.add(new Multiply(array, i, width));
    }

    Rootbeer rootbeer = new Rootbeer();
    rootbeer.runAll(jobs);
  }
}

Multiply.java

import org.trifort.rootbeer.runtime.Kernel;

public class Multiply implements Kernel {

  private int[] m_array;
  private int m_index;
  private int m_width;

  public Multiply(int[] array, int index, int width){
    m_array = array;
    m_index = index;
    m_width = width;
  }

  public void gpuMethod(){
    m_array[m_index] *= m_width;
  }
}

Когда я запускаю этот код, я получаю следующий вывод с ошибкой

array[0] = 0
array[1] = 1
array[2] = 2
array[3] = 3
array[4] = 4
array[5] = 5
array[6] = 6
array[7] = 7
array[8] = 8
array[9] = 9

Что здесь пошло не так?

Обновить

Я сделал это способом, предложенным 2 пользователями. Ниже приведены команды, которые я использовал для вывода.

C:\Users\Dev\Documents\NetBeansProjects\GPU\dist>java -Xmx512m -jar Rootbeer.jar GPU.jar GPU1.jar
C:\Users\Dev\Documents\NetBeansProjects\GPU\dist>java -jar GPU1.jar

Первая команда работала нормально, не стоит беспокоиться. Но второй, когда я пытаюсь запустить Jar под названиемGPU1.JAR это дало мне следующую ошибку.

array[0] = 0
array[1] = 1
array[2] = 2
array[3] = 3
array[4] = 4
array[5] = 5
array[6] = 6
array[7] = 7
array[8] = 8
array[9] = 9
