CosineSimilarity code Explain

[mtsol]

Hello team, I need to know the function call at line 34 in https://github.com/NVIDIA/spark-rapids-examples/blob/branch-22.12/examples/UDF-Examples/RAPIDS-accelerated-UDFs/src/main/java/com/nvidia/spark/rapids/udf/java/CosineSimilarity.java executes on GPU or CPU? And if it executes on CPU then where is the GPU code?
