NVBit consistently is stuck

[Rajat Khandelwal]

On experimenting with NVBit to collect traces, whenever I run the tool, its just stuck on the initial dump and doesn't proceed further.

Can someone help in this matter? Maybe its a very trivial problem, but couldn't get my head around to make the tool finish.

Below is the dump after running the tracer_tool. It doesn't proceed further.

LD_PRELOAD=./tracer_tool/tracer_tool.so ./nvbit_release/test-apps/vectoradd/vectoradd
------------- NVBit (NVidia Binary Instrumentation Tool v1.5.3) Loaded --------------
NVBit core environment variables (mostly for nvbit-devs):
            NVDISASM = nvdisasm - override default nvdisasm found in PATH
            NOBANNER = 0 - if set, does not print this banner
---------------------------------------------------------------------------------
         INSTR_BEGIN = 0 - Beginning of the instruction interval where to apply instrumentation
           INSTR_END = 4294967295 - End of the instruction interval where to apply instrumentation
    EXCLUDE_PRED_OFF = 1 - Exclude predicated off instruction from count
DYNAMIC_KERNEL_LIMIT_END = 0 - Limit of the number kernel to be printed, 0 means no limit
DYNAMIC_KERNEL_LIMIT_START = 0 - start to report kernel from this kernel id, 0 means starts from the beginning, i.e. first kernel
   ACTIVE_FROM_START = 1 - Start instruction tracing from start or wait for cuProfilerStart and cuProfilerStop. If set to 0, DYNAMIC_KERNEL_LIMIT options have no effect
        TOOL_VERBOSE = 1 - Enable verbosity inside the tool
       TOOL_COMPRESS = 1 - Enable traces compression
     TOOL_TRACE_CORE = 0 - write the core id in the traces
TERMINATE_UPON_LIMIT = 0 - Stop the process once the current kernel > DYNAMIC_KERNEL_LIMIT_END
USER_DEFINED_FOLDERS = 0 - Uses the user defined folder TRACES_FOLDER path environment
