Error in running DAAL examples on devloud

[RAror6]

Hello,

I am getting this error when I tried to run the oneDAL example codes in the install directory in DevCloud

/opt/intel/inteloneapi/daal/2021.1-2021beta06/include/oneapi/internal/kernel_scheduler_sycl.h:30:22: fatal error: 'level_zero/ze_api.h' file not found
            #include <level_zero/ze_api.h>

The command I ran was: make sointel64 mode=build

Could I get some help fixing this?

I am also having difficulties with linkers. I tried following the manual in the developers guide, but for some reason it is not working. Could i please get some help with this as well?

Thank you!

Hi,
Sad to inform, but  this is know limitation with Beta06 release. There are 2 workarounds available.
https://oneapi-src.github.io/oneDAL/notes/issues/2021.1-beta06/level-zero-not-found.html

This problem will be permanently fixed in next release.

Thank you for the speedy reply!

Two questions:
1) How do I update my driver? OR
2) Where do insert the command 'export SYCL_BE=PI_OPENCL'

Thank you!

[Nikolay_P_Intel1]

I think that second option should be easier

Most important part would be setting define - #define DAAL_DISABLE_LEVEL_ZERO
SYCL_BE - just have to be exported in your current env - i.e. in shell

Thank you for the helpful reply!

1. The 'SYCL_BE' is missing in the define statement in the linked page on the developer's guide. I was a little confused about that, but now it is sorted out! Thank you

2. Unfortunately, it still gives me the same error. I have tried it multiple times. If i try in the default intallation directory, i get an error of 'recipe for sointel64 failed' but if i copy it to my home directory i get the level_zero error. I am running the command: make sointel64 example=cor_dense_batch

Could I please get some help with this?

Thank you!

Hi,

Please follow the below steps:

1.  cd examples/cpp_sycl
2.  vi ./source/covariance/cor_dense_batch.cpp
      Add and save the below command in the above file

   #define DAAL_DISABLE_LEVEL_ZERO

3. export SYCL_BE=PI_OPENCL

4. vi makefile

    Remove or comment the below command from the Makefile

     LEVEL0_LIB := -lze_loader

5. make sointel64 example=cor_dense_batch
 

Hope this helps. If you have any issue please let us know

Thanks

Thank you for your help!

Still not working :/

I found the line LOPTS := -Wl,--start-group -Wl,$(DAAL_LIB),$(EXT_LIB) $(DAAL_PATH)/libdaal_sycl.a $(LEVEL0_LIB) -Wl,--end-group in the makefile and removed the $(LEVEL0_LIB) part from it (in addition to the other line). Still nothing.

What else could be causing this error?

[Nikolay_P_Intel1]

Do you still getting 'level_zero/ze_api.h' file not found ?

The important action is to add "#define DAAL_DISABLE_LEVEL_ZERO

Hi,

Please follow the complete steps:

1. Copy the daal folder to the home directory:

     cp -r /opt/intel/inteloneapi/daal /home/uxxxxx

2.  cd /home/uxxxxx/daal/<version>

3. Setting up oneDAL environment via vars.sh script
    Run the following command:

      source ./env/vars.sh

4. To build and run DPC++ examples:

      cd examples/cpp_sycl

5. Compile your application without Level Zero support:

      vi /home/uxxxxx/daal/<version>/include/oneapi/internal/kernel_scheduler_sycl.h

   Add and save the below command to the file 

      #define DAAL_DISABLE_LEVEL_ZERO

6. Disable Level Zero runtime:

      export SYCL_BE=PI_OPENCL

7. vi makefile
    
   Remove or comment the below command from the Makefile

      LEVEL0_LIB := -lze_loader

8. make sointel64 example=cor_dense_batch

Hope this helps. If you face any issue please let us know.

Thank you so much! This fixed the error.

My mistake was not adding the define statement in the kernel_scheduler.h file. I was adding it in the source code for _cor_dense.

Thank you again!
