Q:-1 Difference between GPU Kernels and TPC Kernels
eg: GPUTPCCFDecodeZS 
GPUTPCCFCheckPadBaseline 
GPUTPCCFPeakFinder
 
eg: TPC Sector Tracking
TPC Track Merging and Fit
 
Q:-2 GPU.out and CPU.out are different. 
 
Q:-3 When we enable -DGPUCA_DETERMINISTIC_MODE Cmake setting or
--PROCdeterministicGPUReconstruction
GPU.out is same but --RTCdeterministic command line option
GPU.out is not same.
 
Google Doc with timings of different kernels for the deterministic mode.
