OpenCL application hangs FPGA

Hello:

I am trying to run a multithreaded OpenCL + OpenMP (host side) application on Devcloud that targets FPGA. It worked fine around 2 weeks ago. However, it is now hanging after a call to clFlush that follows a call to clEnqueueWriteBuffer. Has anything changed in the Devcloud environment that explains this issue? Could you tell me how to address this?

Thanks.

    Can you tell us whether you are using FPGA emulator or FPGA device.Also please share the job submission command.

      I'm launching it from interactive mode with:
      qsub -I -l nodes=1:fpga_runtime:ppn=2 -d.

      The application works well with the emulator. It only hangs with the FPGA device.

      Thank you
