Formulas:
PCI read bandwidth [MBytes/s] = 1.0E-06*(BUS_READ_TOTAL_PCI)*256.0/runtime
PCI read data volume [GBytes] = 1.0E-09*(BUS_READ_TOTAL_PCI)*256.0
PCI write bandwidth [MBytes/s] = 1.0E-06*(BUS_WRITE_TOTAL_PCI)*256.0/runtime
PCI write data volume [GBytes] = 1.0E-09*(BUS_WRITE_TOTAL_PCI)*256.0
PCI bandwidth [MBytes/s] = 1.0E-06*(BUS_READ_TOTAL_PCI+BUS_WRITE_TOTAL_PCI)*256.0/runtime
PCI data volume [GBytes] = 1.0E-09*(BUS_READ_TOTAL_PCI+BUS_WRITE_TOTAL_PCI)*256.0
