I have been trying to use the inclusive prefix scan, but I keep getting an “Unhandled Exception” error. The code is as follows:
n = 4
key = [2,1,0,1];
thrust::inclusive_scan(key, key + n, key);
I tried to follow the example given here:
I usually associate “Unhandled Exception” with trying to access a point outside an array, but I have also tried key+n-1 as well as key+1 in the middle term, both of which gave me the same “Unhandled Exception”.
Thanks for any help you guys can provide.
Even I am getting the same problem…
I am using windows 7 enterprise edition (32 bit), GTX 580, CUDA 4.1, Visual Studio 2010, with code Generation set to compute_20,sm_20;
the same code is working fine with code Generation set to compute_10,sm_10;
Thanks in advance.
My guess is that you are compiling in Debug mode.
Unfortunately, nvcc 4.1 -G doesn’t support Thrust. To workaround the problem, switch to release mode or use sm_1X if you can.
