EXCEPTION_ACCESS_VIOLATION (0xc0000005)

Hello,

I’ve tried setting up JCuda and are attempting to implement an example of graph traversal from the nvgraph library. Whenever I attempt to execute the code I get a fatal error.
The error is caused by attempting to initialize the traversal parameters using nvgraphTraversalParameterInit.

 public static void main(String[] args)
{
	JCuda.setExceptionsEnabled(true);
    JNvgraph.setExceptionsEnabled(true);
    // Graph CSR format
    int n = 7, nnz = 12, vertex_numsets = 2, edge_numsets = 0;
    int source_offsets_h[] = {0, 1, 3, 4, 6, 8, 10, 12};
    int destination_indices_h[] = {5, 0, 2, 0, 4, 5, 2, 3, 3, 4, 1, 5};
    // Result storage
    int bfs_distances_h[] = new int[n];
    int bfs_predesseors_h[] = new int[n];
    // nvgraph variables
    nvgraphStatus status;
    nvgraphHandle handle = new nvgraphHandle();
    nvgraphGraphDescr graph = new nvgraphGraphDescr();
    nvgraphCSRTopology32I CSR_input = new nvgraphCSRTopology32I(); 
    nvgraphTraversalParameter traversal_param = new nvgraphTraversalParameter();
    int vertex_dimT[] = new int[vertex_numsets];
    int distances_index = 0;
    int predecessors_index = 1;
    vertex_dimT[distances_index] = cudaDataType.CUDA_R_32I;
    vertex_dimT[predecessors_index] = cudaDataType.CUDA_R_32I;
    
    check_status(nvgraphCreate(handle));
    check_status(nvgraphCreateGraphDescr(handle, graph));
    
    CSR_input.nvertices = n;
    CSR_input.nedges = nnz;
    Pointer s_o_h_p = Pointer.to(source_offsets_h);
    Pointer d_i_h_p = Pointer.to(destination_indices_h);
    
    CSR_input.source_offsets = s_o_h_p;
    CSR_input.destination_indices = d_i_h_p;
    
   nvgraphSetGraphStructure(
    		handle, graph, CSR_input, NVGRAPH_CSR_32);
   nvgraphAllocateVertexData(
    		handle, graph, vertex_numsets, Pointer.to(vertex_dimT));
    int source_vert = 1;
    JCuda.cudaMalloc(s_o_h_p, n*Sizeof.INT);
    JCuda.cudaMalloc(d_i_h_p, n*Sizeof.INT);
    
    System.out.println("hej");
    nvgraphTraversalParameterInit(traversal_param);
    nvgraphTraversalSetDistancesIndex(traversal_param, distances_index);
    nvgraphTraversalSetPredecessorsIndex(traversal_param, predecessors_index);
    nvgraphTraversalSetUndirectedFlag(traversal_param, 0);
    
    check_status(nvgraphTraversal(handle, graph, NVGRAPH_TRAVERSAL_BFS, Pointer.to(new int[] {source_vert}),traversal_param));
    check_status(nvgraphGetVertexData(handle, graph, Pointer.to(bfs_distances_h), distances_index));
    check_status(nvgraphGetVertexData(handle, graph, Pointer.to(bfs_predesseors_h), predecessors_index));
    //expect bfs distances_h = (1 0 1 3 3 2 2147483647)
    for(int i = 0; i<n; i++) System.out.print("Distance to vertex: " + i + " is: " + bfs_distances_h[i]);
    System.out.println();
    // expect bfs predecessors = (1 -1 1 5 5 0 -1)
    for(int i = 0; i<n; i++) System.out.print("Predecessor of vertex: " + i + " is: " + bfs_predesseors_h[i]);
    System.out.println("Done");
    check_status(nvgraphDestroyGraphDescr(handle, graph));
    check_status(nvgraphDestroy(handle));

}

When I run the JCuda samples the code runs perfectly fine.

Hello,

Sorry about that. There indeed was a bug in the initialization of the traversal helper structures. Admittedly, JNvgraph has not been tested extensively: I only ported the examples from the manual, to make them available as samples, and as a very basic test, but obviously, this was not sufficient to spot this error. The bug is now fixed via this commit: https://github.com/jcuda/jnvgraph/commit/5a615b46298dfd58c44e7681f1e2e987fa0c16e2

With this change, the following standalone version of your test passes and prints the expected results:

But it may be important to point out: According to the release notes of the latest CUDA release, section “CUDA libraries”:

The nvGRAPH library is deprecated. The library will no longer be shipped in future releases of the CUDA toolkit.

However, regarding the fix: I could schedule a bugfix release for that. But even though it is “critical” (in that it simply does not work, and there is no workaround), it is a very narrow and specific issue, and the library is about to be deprecated, so I’m not entirely sure about that.

If you want to do some experiments despite the deprecation, it’s possible to compile the latest version of the native library (including the fix), and just drop the resulting native library as a file in the project directory. The library loader will then pick up the fixed file. (If you’re on Windows, I could also upload the fixed library).

Again, sorry for the hassle
Marco

Thanks for the reply.

I would like to experiment a bit with nvgraph even though it’s deprecated.
Right now I’m just testing out wheter it’s worth it to move to some sort of GPU based graph traversal for a project I’m working on.

I’m restricted to windows at the moment so if you could upload the fixed library that would be cool.

Again, thanks for the help man!
