  1. POclSetKernelArg returning error code -49
    text
    copied!<p>I have written the following C++ code. At <code>clSetKernelArg( kernel, 8, sizeof( cl_mem ), (void *) &amp;mob_whdis );</code>, it returns <code>error code -49</code>, and I don't understand why. Everything else runs properly. Can anyone help me?</p> <pre><code>cl_mem mob_X = NULL; cl_mem mob_Y = NULL; cl_mem mob_Z = NULL; cl_mem mob_WAT = NULL; cl_mem mob_POL = NULL; cl_mem mob_FSW = NULL; cl_mem mob_nop = NULL; cl_mem mob_nofsw = NULL; cl_mem mob_whdis = NULL; cl_mem mob_watwp = NULL; cl_mem mob_watp = NULL; cl_mem mob_distp = NULL; cl_mem mob_watww = NULL; cl_mem mob_watw = NULL; cl_mem mob_distw = NULL; cl_program program = NULL; cl_kernel kernel = NULL; cl_uint ret_num_devices; cl_uint ret_num_platforms; cl_int err; float whdis=3.5; mob_X = clCreateBuffer( context, CL_MEM_READ_WRITE, na * sizeof(float), NULL, &amp;err ); mob_Y = clCreateBuffer( context, CL_MEM_READ_WRITE, na * sizeof(float), NULL, &amp;err ); mob_Z = clCreateBuffer( context, CL_MEM_READ_WRITE, na * sizeof(float), NULL, &amp;err ); mob_WAT = clCreateBuffer( context, CL_MEM_READ_WRITE, now * sizeof(int), NULL, &amp;err ); mob_POL = clCreateBuffer( context, CL_MEM_READ_WRITE, nop * sizeof(int), NULL, &amp;err ); mob_FSW = clCreateBuffer( context, CL_MEM_READ_WRITE, now * sizeof(int), NULL, &amp;err ); mob_nop = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int), NULL, &amp;err ); mob_nofsw = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int), NULL, &amp;err ); mob_whdis = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(float), NULL, &amp;err ); mob_watwp = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int) * now * 40, NULL, &amp;err ); mob_watp = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int) * now * 40, NULL, &amp;err ); mob_distp = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(float) * now * 40, NULL, &amp;err ); mob_watww = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int) * now * 40, NULL, &amp;err ); mob_watw = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(int) * now * 40, NULL, &amp;err ); mob_distw = clCreateBuffer( context, CL_MEM_READ_WRITE, sizeof(float) * now * 40, NULL, &amp;err ); err = clEnqueueWriteBuffer( command_queue, mob_X, CL_TRUE, 0, na * sizeof(float), X, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_Y, CL_TRUE, 0, na * sizeof(float), Y, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_Z, CL_TRUE, 0, na * sizeof(float), Z, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_WAT, CL_TRUE, 0, now * sizeof(int), wat, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_POL, CL_TRUE, 0, nop * sizeof(int), pol, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_FSW, CL_TRUE, 0, now * sizeof(int), fsw, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_nop, CL_TRUE, 0, sizeof(int), &amp;nop, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_nofsw, CL_TRUE, 0, sizeof(int), &amp;nofsw, 0, NULL, NULL ); err = clEnqueueWriteBuffer( command_queue, mob_whdis, CL_TRUE, 0, sizeof(float), &amp;whdis, 0, NULL, NULL ); err_check( err, "clSetKernelArg" ); err = clSetKernelArg( kernel, 0, sizeof( cl_mem ), (void *) &amp;mob_X ); err = clSetKernelArg( kernel, 1, sizeof( cl_mem ), (void *) &amp;mob_Y ); err = clSetKernelArg( kernel, 2, sizeof( cl_mem ), (void *) &amp;mob_Z ); err = clSetKernelArg( kernel, 3, sizeof( cl_mem ), (void *) &amp;mob_WAT ); err = clSetKernelArg( kernel, 4, sizeof( cl_mem ), (void *) &amp;mob_POL ); err = clSetKernelArg( kernel, 5, sizeof( cl_mem ), (void *) &amp;mob_FSW ); err = clSetKernelArg( kernel, 6, sizeof( cl_mem ), (void *) &amp;mob_nop ); err = clSetKernelArg( kernel, 7, sizeof( cl_mem ), (void *) &amp;mob_nofsw ); err = clSetKernelArg( kernel, 8, sizeof( cl_mem ), (void *) &amp;mob_whdis ); // Step 11: Execute OpenCL kernel in data parallel size_t worksize[] = { now, 1, 1 }; clEnqueueNDRangeKernel( command_queue, kernel, 1, NULL, worksize, 0, 0, 0, 0 ); err_check( err, "clEnqueueNDRangeKernel" ); // Step 12: Read (Transfer result) from the memory buffer </code></pre>
