Some applications launch many tiny kernels, making them prone to very large (100s of megabytes or larger) nvprof timeline dumps, even for application runs of only a handful of seconds. Such nvprof files may fail to even load when you try to import them into the NVIDIA Visual Profiler (NVVP). One symptom of this problem…

On at least some platforms, these options can also be triggered via the JAVA_TOOL_OPTIONS environment variable . This is in particular useful where you don't have root privileges.

For example, for 200gb memory, in a bash shell, you would use:

$ export JAVA_TOOL_OPTIONS=" -Xmx200g"

Or alternatively, set a temporary environment variable:

$ nvvp JAVA_TOOL_OPTIONS=" -Xmx200g"

Hi, Jacob:

I suggest you take your issue to the NVIDIA developer forums at devtalk.nvidia.com.
