How to get ALU per invocation of OpenCL kernel in MALI-immortalis g715 MC 11 from streamline?

Yash Agrawal 7 months ago

To get ALU/invocation:

ALU Count: CVT + SFU + FMA instructions * 11 (11 cores)

invocations: $MaliCoreNonFragmentWarps * 16

Is the above calculation Right?

Don't need the x 11 - it cancels out with the same x11 you need for the warp count. This should do it:

((CVT + SFU + FMA) * 4) / ($MaliCoreNonFragmentWarps * 16)

Thanks Peter for replying.

1. Why we are multiplying by 4 the total instructions?

2. Are the CVT instructions count for all warps or all threads executed over the cores?

Mali-G715 contains 4 processing units per core, the performance counters only count instructions in PU0.

All the instruction issues counters count per warp.
