about multi-streaming

[weijizhen]

I want to know how to modify to multi-stream, where can I see if it is multi-stream?
The following code can only be 0, because config.get_stream() is NULL.

in libcuda/cuda_runtime_api.cc:941
struct CUstream_st *stream = config.get_stream();

I'm not sure I fully understand your question. If you have an application with multi-stream support (e.g., Huffman: https://github.com/accel-sim/gpu-app-collection/blob/release/src/cuda/rodinia/3.1/cuda/huffman/hist.cu#L89) it should run in GPGPU-Sim today. The line of code you point to would return 0 in an application that only has 1 stream though, because the default stream is stream 0.

So, are you running an application that has multiple streams?
