How to profile PCI transfer with aocl report?

[Altera_Forum]

With the IntelFPGA SDK 17.0, the Dynamic Profiler for OpenCL GUI (report) is showing me only the kernel execution time but not the PCI transfers. 

However, I remember seeing the PCI transfer with an older SDK version and another board,  Does somebody know how to show it, if it was removed or if it depends from board to board?

Generally you would set the environment variable ACL_PROFILE_TIMER to 1 before profiling your code if you wanted to show the memory transfers in the report. 

 The best practices guide has a small brief of it https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/opencl-sdk/aocl-best-practices-guide.pdf#_opentopic_toc_processing_d116e11390

Can you please tell me how to set that variable because when I tried I am not able to see PCIE transfer time ?
