I tried to do the homework assignments of udacity's famous parallel programming(cs344) course. I found a repository in github that using google colab platform did it. udacity-cs344-colab

I tried to run that reposiotory in colab but I got errors.

When I run the cell

# make the cuda project
!make HW1
print("\n====== RESULT OF HW1 =======\n")
!bin/HW1 ../src/HW1/cinque_terre.gold

I get an error like this:

[ 20%] Building NVCC (Device) object HW1/CMakeFiles/HW1.dir/HW1_generated_student_func.cu.o
nvcc fatal   : Unsupported gpu architecture 'compute_30'
CMake Error at HW1_generated_student_func.cu.o.cmake:222

    CUDA 11.x will not allow builds that include [this line](https://github.com/depctg/udacity-cs344-colab/blob/master/src/CMakeLists.txt#L24). So remove that line. That is what is being indicated in the linked duplicate. – Robert Crovella Mar 22 '21 at 19:56

    For example, after starting the first (HW1) notebook, in the very first cell, before the last line of that cell which is `!cmake ../src`, insert this line: `!sed -i '24d' ../src/CMakeLists.txt` then execute that cell and proceed with the notebook. – Robert Crovella Mar 22 '21 at 20:26
  • Yes, this is a duplicate and your edit removed the exact source of your problem, wich is trying to build for an unsupported GPU architecture – talonmies Mar 22 '21 at 20:27
  • Thanks a lot @RobertCrovella, it worked for me. – Cavidan Mar 23 '21 at 15:53
