Is it possible to collect statistics about L1/L2 TLB Miss on an Intel Haswell processor with amplxe-cl?

If yes, what is the correct syntax to do so with amplxe-cl?

There are events and metrics around ITLB and DTLB misses.  Please see the tuning guides.  You didn't say desktop or server, so you need to pick the appropriate guide.

General Exploration ('-c general-exploration' command line option) collects all relevant metrics referenced in the tuning guide.

For memory specific information, you might check out the memory-access analysis type.  

In both cases, you can review the metric formulas and create a custom analysis type to collect only those events - though you will have to calculate the formulas yourself, in that case.

Ok that worked, thanks.

Would you be able to give examples of metrics concerning DTLB?
