Exception in running vector-add on FPGA device on arria10 devcloud

[amaltaha]

Hello, 

I am trying to run vector-add of fpga_compile example on Intel oneAPI devcloud on hardware FPGA by ./fpga_compile.fpga 

I have connected through ssh on MobaXterm and I have specified the node to be s001-n083 which runs fpga and its state was free, but now it shows job-execlusive,  I have walked through the steps one by one and the fpga emulation works normally, I do the steps (in the build file):

1- cmake ..

2- make fpga

then I wait for 2 hours for the queue, then:

3- ./fpga_compile.fpga

and I receive this error:

Running on device: pac_a10 : Intel PAC Platform (pac_ee00000)
Caught a SYCL host exception:
Native API failed. Native API returns: -42 (CL_INVALID_BINARY) -42 (CL_INVALID_BINARY)

what(): Native API failed. Native API returns: -42 (CL_INVALID_BINARY) -42 (CL_INVALID_BINARY)

I get a different error when I try to run it on Stratix 10. which is:

 Caught a SYCL host exception:

Hi amaltaha,

I have tried to run the vector add example:

https://github.com/oneapi-src/oneAPI-samples/tree/master/DirectProgramming/DPC%2B%2B/DenseLinearAlgebra/vector-add

It was ok from my side where I was able to run the whole program following the document without errors.

Sometimes the nodes may encounter issues and is better to retry again or on other nodes.

Thanks.

[amaltaha · Accepted solution]

using the command 

dpcpp -fintelfpga -Xshardware <source_file>.cpp 

Solved the problem, make fpga didn't work on any node. probably the problem is in my side.

Thank you!
