News from GPU parameter tuning

• Started performance study on standalone-benchmark on different GPUs
• Selected datasets:
  • Real PbPb data (lhc24_ar)
  • Simulated PbPb 47kHz data
  • Real pp data?
• Fixed O2 release
• For each GPU
  • For each dataset
    • Tune parameters for that release
    • Measure sync wall time with RTC
    • Measure async wall time without RTC
      
      

• json GPU params ready ✅
• Generation triggered by changes on json
• Defaults header generated into ${CMAKE_BINARY_DIR}/GPU/GPUTracking/GPUDefParametersDefaults.h
• MI100, VEGA, AMPERE, TURING headers generated along .par files
  DEBUG:O2:O2:0: [5/11] Generating GPU parameter header for AMPERE

• Todo:
  • Correctness tests
  • CSVtoJSON script
