+When oversampling data, the default value of an empty bin is 0. That said, the default empty
 value can be overridden by an option named parameter, e.g., `empty_bin_val=100`.
 This is often useful when the default value is part of the data range, and setting
 the empty bin value to something known, allows the user to filter out empty bins

+Using ROCm-SMI on AMD GPUs
+--------------------------
+ROCm-SMI stands for ROCm System Management Interface and provides an interfaces for applications and users to monitor and control GPU applicatoins. 
+
+ROCm-SMI can be used to verify GPU usage. 
+This is done by launching your application and then using ROCm-SMI on the same node to monitor the running job.

 Using RocProf on AMD GPUs
 -------------------------
 RocProf is a command line tool provided by ROCm that is implemented on top of the rocProfiler and rocTracer APIs.
