    Hi @adarsh_m,

    Thank you for posting in Intel community forum and hope all is well.
    Mind if I ask on which node that you are facing the error? As well as which example design are you compiling with which command?
    Hope to hear from you soon.

    Best Wishes

    Thanks for responding @BoonBengT_Altera

    hello ,
    i am submitting Jobs on FPGA nodes available on Devcloud . i am compiling using Makefile and submitting using qsub as shown below part of Makefile and submission steps
    Makefile part
    _________________________________________________________________________________
    fpga : CXXFLAGS += -DFPGA
    fpga : cleanfpga \
    $(TARGET_DIR)/$(TARGETHfpga)
    aoc -v ${CLFILENAME}.cl -o bin/${CLFILENAME}.aocx
    d=$$(date +%s%N)\
    ; cd $(TARGET_DIR) && ./$(TARGETHfpga) \
    && echo " ______________________$@ Build took $$(($$(($$(date +%s%N)-d))/1000000)) mili seconds____________________"

    _____________________________________________________________________________________
    Submission using :
    _______________________________________________________________________________________
    " qsub -l walltime=24:00:00 -l nodes=1:fpga:ppn=2 -d . fpga "

    Hi @adarsh_m,

    Thanks for the details, is it correct to say that you are trying to execute a Opencl kernel design on an FPGA?
    I am still trying to understand the situation or to simulate the issues, will it be possible for you to share the example design you are building and makefile that you using to compile.

    PFA ,Makefile and kernel file nbody.cl also can you tell why only one job gets to run previously 3-5 jobs would start running .These days except one all remain in queue waiting.

      Hi @adarsh_m,

      Apologies for the hold up, if above qsub command are run in the headnode, sometimes it might cause error such as missing files/dependencies.
      Hence, recommended steps for that is to use the devcloud_login command to access the desire nodes with kits, and run the batch command.
      Please do try and let us know if that helps.
