Hi,

I am facing a problem of “Cuda error: freeSegmentedScanStorage”. Anyone have idea why i get this error?

Here is a part of source code, it is doing the segmented Scan.


        CUDPPConfiguration config3 = new CUDPPConfiguration();
        config3.op = CUDPP_ADD;
        config3.datatype = CUDPP_INT;
        config3.algorithm = CUDPP_SEGMENTED_SCAN;
        config3.options = CUDPP_OPTION_FORWARD | CUDPP_OPTION_INCLUSIVE;
        CUDPPHandle handle3 = new CUDPPHandle();
        cudppPlan(handle3, config3, length, 1, 0);
        cudppSegmentedScan(handle3, segmentScan_odata, segmentScan_idata, segmentFlag, length);
        cudaThreadSynchronize();  

        cudppDestroyPlan(handle3);            //->got exception here
        cuMemFree(segmentScan_idata);
        cuMemFree(segmentFlag);
       



Cuda error: freeSegmentedScanStorage in file '/home/kashif/c++/RIPS/C/cudpp/src/app/segmented_scan_app.cu' in line 358 : unspecified launch failure.

I found in the segmented_scan_app.cu, the line 358 is:

CUT_CHECK_ERROR(“freeSegmentedScanStorage”)

Thanks.

Regards,
Lemon

Hello

A small, self-contained (compileable) example where it is possible to reproduce the error might be helpful, then I can have a look at this ASAP.
