DevCloud OneAPI for ESIMD: No device of requested type available

[Hongbo_R_Intel]

Hello,

I tried to compile and run SYCL with ESIMD extension on Intel FPGA DevCloud with its pre-installed OneAPI tools. Here is the procedure and an error I got:

1. ssh devcloud

2. devcloud_login  (choose 2, 4, or 5)

3. git clone https://github.com/intel/llvm-test-suite.git

4. cd llvm-test-suite/SYCL/ESIMD

5. dpcpp stencil2.cpp -O0 -g
6. ./a.out
     width = 64 height = 64
    terminate called after throwing an instance of 'cl::sycl::runtime_error' 
    what(): No device of requested type available. Please check https://software.intel.com/content/www/us/en/develop/articles/intel-oneapi-dpcpp-system-requirements.html -1 (CL_DEVICE_NOT_FOUND)
Aborted

I did a little debugging: 

      gdb-oneapi a.out

Here is the stack:

(gdb) bt

Additional info: the machine I used is s001-n056, and

$ dpcpp --version

Thanks!

Hi @Hongbo_R_Intel,

Thank you for posting in Intel community forum and hope all is well.
We are trying to run the similar steps to further understand the situation.
At the time being do notice that the node mention 's001-n056' are not listed as a valid node. (which might explain the device not found error)

Hence can you try to select with A10 oneAPI and see if that solve the problem.
Hope to hear from you soon.

Thanks for the reply, BB. You may "devcloud_login", and choose 2, 4 or 5 for any machine with oneapi, not necessarily s001-n056. They all have the same issue.

Hi @HongboRong,

Yes you are right, all the nodes for 2, 4 and 5 are having the same issues.
My guess is that those nodes does not comes with required gpu.
To request for a GPU node, you would be able to so do with the command below:
qsub -I -l nodes=1:gpu:ppn=2 -d .

Once in the node level and you should be able to run the executable result accordingly.
Please do let us know if that helps.

Note: More details on the job submission in Intel Devcloud can be found here.

Thanks, BB. That works!
