Vectoradd build error

Hi,

On my first attempt, I wasn't able to build the vector add example. Please see the following output:

So, how can I fix the shared library error?

Hi,

Good day to you.

Thank you for posting in Intel Communities.

Please follow the steps to build and run the Base: Vector Add Sample in Intel® DevCloud :

Note: Since Intel® DevCloud for oneAPI includes the appropriate development environment already configured, you do not need to set environment variables.

1. Change to the sample directory:

cd oneAPI-samples/DirectProgramming/C++SYCL/DenseLinearAlgebra/vector-add

2. In that build.sh script please add the below commands:

     a) Configure the build system with these commands:

mkdir build
cd build
cmake ..

  b) Build the program using this command:

 make all

3. You can specify a GPU node and run the script file using a single-line script:

qsub -l nodes=1:gpu:ppn=2 -d . build.sh

4. Run the program with the below command:

./vector-add-buffers

To get a detailed understanding of running the vector-add sample please follow this link: https://github.com/oneapi-src/oneAPI-samples/tree/master/DirectProgramming/C%2B%2BSYCL/DenseLinearAlgebra/vector-add

If this resolves your issue, make sure to accept this as a solution. 

This would help others with similar issue. Thank you!

Thanks and Regards,

Diya

Hi, 

Note : The above solution is for running a build.sh script(batch mode)for CPU/GPU/FPGA nodes.

              The error was coming because you were trying to run in a login node, we should request a node and then do the rest of the job.

Please follow the steps to build and run the Base: Vector Add Sample in Intel® DevCloud using interactive mode in FPGA Node:

1.  When you are requesting an FPGA Node explicitly please give the below command:

 qsub -I -l nodes=1:arria10:ppn=2

2. Change to the sample directory by giving this command:

cd oneAPI-samples/DirectProgramming/C++SYCL/DenseLinearAlgebra/vector-add

3. Configure the project to use the buffer-based implementation by giving this command:

mkdir build
cd build
cmake ..

4. Build and run the program using the below command: 

make fpga_emu
./vector-add-buffers.fpga_emu

Please have a look at the above screenshot to get a clear picture of how it is happening.

To get a detailed understanding of running the vector-add sample please follow this link : https://github.com/oneapi-src/oneAPI-samples/tree/master/DirectProgramming/C%2B%2BSYCL/DenseLinearAlgebra/vector-add

If this resolves your issue, make sure to accept this as a solution.

Hi ,

Glad to know that your issue is resolved. If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.

Regards,

I've managed to resolve the same issue following the solution doing the exercise without FPGA support, that is by requesting a GPU node using the following command:

qsub -I -l nodes=1:gpu:ppn=2

and running all `cmake` and `make` commands from within the interactive mode. However, I'd like to be able to build the application without the interactive mode (as initially described) using the following command:

qsub -l nodes=1:gpu:ppn=2 -d . build.sh

where all `cmake` and `make` commands are run from the `build.sh` script. I get the same error about the same shared library error which makes me think that some module needs to be loaded, doesn't it? If yes, which module needs to be loaded? Otherwise, why isn't it working exactly as it is described initially?

Hi Diya,

How to run this vector-add project on fpga using "qsub -I -l nodes=1:arria10:ppn=2"?

I followed this tutorial.

However, I met this following mistake. Any help would be appreciate! 

Thank you,

Wan
