    streamScatterOp

    bayoumi
      Hi,
      I understand that streamScatterOp is still not fully supported, but I read on the forum people using it. I decided to give it a try under Windows XP x64, and latest SDK.

      I tried to run brcc & C/C++ cl/link on the scatter_gather.br which comes under Brook+ samples with the SDK.
      I always get an error complaining from undefined variable corresponding to the reduce function. For example:
      ....
      ...
      reduce void sub(float a<>, reduce float b<>)
      {
      b = a - 1;
      }
      ...
      ...
      streamScatterOp(soutput1D, sindices1D, input1D, sub);
      ....

      I always get : undefined __sub_inner_cpu from the C/C++

      Thanks
      Amr
