Trace starting from high cycle count

[Nikhil Bhave]

Hello 

While trying to generate a trace file from Sniper in order to feed it to NVMain, we modified the sniper source code slightly(in the file dram_cntrl.cc) to back-calculate the number of cycles from time elapsed. Here is the code we used: 

double second = now.getFS() / pow(10, 15);

double cycle = second * pow(10, 9) * 2.6;

Here, cycle is the variable that should ideally give us the cycle count. However, when we compiled and ran sniper with parsec benchmark, we got a very high starting cycle count, approximately 340,000. What could be the reason for this?

Hello, I have the same problem. Have you had a solution for this?

Thank you!
