Code Project For Course ECE408

This is code project for ECE408(Applied Parallel Programming). And you can use this project as a good start for your own lab implementation. Here's how you finish your own project. You can get all slices here.

1. Compile & Run

First make sure that CMake and development tools are installed in your machine, then enter the following command:

mkdir build
cd build
cmake ..
make 

2. Finish your own code based on template code

./templates/mpx_template.cu are template codes and you need to full fill these code files. For me, I add these implementations in ./imp/mpx.cu.

3. Add your code to CmakeLists.txt

Once you finish your new implementation code, you need to add it to CmakeLists.txt so it can be compiled.

// mpx_implement.cu is your implementation code file name.
CUDA_ADD_EXECUTABLE(MPX_Implement /path/to/your/mpx_implement.cu ${wbhdr} ${wbsrc})

Executable files will be generated in under ./build/bin, and any time when you update your implementation you just need to rerun make under ./build. But if you update your CmakeLists.txt, you should run cmake .. first and then run make to compile all codes.

Test Dataset

datasets for code test are under ./test_data, you can use them to test your implementation with

# suppose you are in ./build directory

./bin/program -e <expected_output_file> -i <input_file_1>,<input_file_2> -o <output_file> -t <type>

The <expected_output_file> and <input_file_n> are the input and output files provided in the dataset. The <output_file> is the location you’d like to place the output from your program. The<type> is the output file type: vector, matrix, or image. If an MP does not expect an input or output, then pass none as the parameter.

For example, if you want test mp3_implementatiton, you can run

# suppose you are in ./build directory

./bin/MP3_Implement -e ../test_data/mp03/0/output.raw \
-i ../test_data/mp03/0/input0.raw,../test_data/mp03/0/input1.raw \
-o ../test_data/mp03/0/res.raw \
-t matrix

# or you can just enter in one line
./bin/MP3_Implement -e ../test_data/mp03/0/output.raw -i ../test_data/mp03/0/input0.raw,../test_data/mp03/0/input1.raw -o ../test_data/mp03/0/res.raw -t matrix

NOTE: If there are one more inputs which have different types, see source code to get correct order of these inputs!

For example, in MP6

// file mp6.cu
inputImageFile = wbArg_getInputFile(arg, 0);    // 1st input
inputMaskFile = wbArg_getInputFile(arg, 1);     // 2nd input
// and so on...

And if you see logs like this, then congratulations, you have passed the test!

"solution_exists": true,
"solution":{
"correctq": true,
"message": "Solution is correct."
}

Generate your own dataset

You can generate your own dataset if you want more test. For example, you can use MP2_Dataset to generate dataset.

MP2_Dataset -d /data/directory -ra 100 -ca 128 -rb 128 -cb 256

NOTE: /data/directory must exist.
