Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.I want to write to 2 or 3 program with aparapi , I don't know anything about 
Opencl, so I ask how i learn aparapi?!!
2.My first program that i want to read is Breadth first search on graph , i 
write serial code and openmp code!my serial code is here :
do{
         stop=false;

            for (i = 0; i < noOfNodes ; i++)
            {
                if (mask[i] && curLevel == nodesArray[i].curIndex ){//if mask node true and cureIndex equal with current level cand be find neighbours
                    for (j = 0; j < nodesArray[i].numNeighbours; j++){
                        tempIndex = nodesArray[i].neighbours[j];
                        if (!visited[tempIndex]){//if visited=true then before find neighbours
                            mask[tempIndex] = true;
                            visited[tempIndex] = true;//go to true
                            parent[tempIndex] = i;
                            stop = true;
                            nodesArray[tempIndex].curIndex=curLevel+1;
                            distance[tempIndex] = distance[i] + 1;
                        }// end  if
                    }//end for j
                }
            }//end parallel for

}while(stop);
3.I use intellijidea and it was help to me to write this code but not working , 
i don't know how to write this program correctly!

 do{
            stop[0] = false;

            //for (i = 0; i < vectFirst.zie(); i++)

            Kernel kernel = new Kernel() {
                @Override
                public void run() {
                    int i=getGlobalId();
                        if (mask[i] && curLevel[0] == nodesArray[i].curIndex ){//if mask node true and cureIndex equal with current level cand be find neighbours
                            for (j[0] = 0; j[0] < nodesArray[i].numNeighbours; j[0]++){
                                tempIndex[0] = nodesArray[i].neighbours[j[0]];
                                if (!visited[tempIndex[0]]){//if visited=true then before find neighbours
                                    mask[tempIndex[0]] = true;
                                    visited[tempIndex[0]] = true;//go to true
                                    parent[tempIndex[0]] = i;
                                    stop[0] = true;
                                    System.out.println("!visited["+i+"] so Node "+tempIndex[0]+" Are neighbour");
                                    nodesArray[tempIndex[0]].curIndex=curLevel[0]+1;
                                    distance[tempIndex[0]] = distance[i] + 1;
                                }// end  if
                            }//end for j
                        }
                }
            };
            Range range = Range.create(noOfNodes);
            kernel.execute(range);
    curLevel[0]++;
        } while (stop[0]);

What is the expected output? What do you see instead?
** No compile error , output is some error after run it!:

i read this link i think that i have to change my data structure and i can not 
use class objects like graph

So Aparapi will not let you use 'new'.  You cannot allocate on the GPU

Looking at your code, I suspect the 'new' is coming from your use of 
System.out.println(....) which is creating a 'new' StringBuilder behind the 
scenes.

Comment this line out and see what happens
