Intel® Memory Latency Checker v2 with buffer option

Jump to solution

Hello,

the documentation of the Intel Memory Latency Checker states that with the option -bXXX you can specify the buffer size. For example to measure caches instead of DRAM. But this option will not considered for execution. The print message "Using buffer size of" as well as the measures values indicate that it not works. For example mlc --idle_latency –b3000 –c0 –t3 out of the documentation will not work. Is there a workaround?

 

Kind regards,
Steffen

Steffen,

the minus in front of the "b" looks different than the minus in front of the "idle_latency" or the "v". Might this be some artifact of copy-and-paste that screwed up your command line? In other words, is the character before the "b3000" really a minus sign?

Kind regards

That should work and I can't reproduce the problem. Can you please send a screen shot of the output

Hello please find attached the screenshot. The message says: Using buffer size of 200.000MB instead of the specified 3 MB (-b3000)

 

Thanks,

Steffen
