Hello
I am using OpenCL on Gen9.5 architecture and I am using i7-7700k processor. I want to have something similar to clock function inside my kernel. What I want to do is something similar to
__kernel void TimeMeasurementKernel(){
//get current clock value
t0 = clock();
//someoperations
t1 = clock();
time_elapsed_to_execute_operations = t1 - t0;
}But it seems that intel doesn't provide any means to get the clock value from inside the OpenCL kernel. But there is a timestamp architecture register tm0 as mentioned in here. My goal is to query this timestamp register from inside the kernel. So one of the way that I thought of, if possible, then to generate the .gen assembly file first by using ioc64 offline compiler using the -asm option, modify the assembly file by introducing the timestamp register opcode and then generate the binary from the modified assembly. I would be able to load the modified binary through the clCreateProgramWithBinary. I am not sure if this is possible. But if it is doable then I would very much appreciate if someone could provide some sort of working example as to how I can do this, specially introducing the timestamp register by modifying the generated assembly from ioc64 and then creating the binary file from the modified assembly.
Also as I have stated my goal is to read the timestamp register, if this similar thing can be achieved by any other method then that would do as well. All I want to gather is the execution time of a portion of my code during runtime. Please let me know if any further information is required. Thank you.
