How to profile memory allocation?

[Neil_Henderson]

Hi,

Can anyone recommend the best way to use VTune to profile an application and find out whether memory allocation is a bottleneck please? Are there certain counters to use?

Thanks,

Neil

Hi Neil,

I suppose there is no event counter in VTune Analyzer to support "memory allocation" measurement.

We have "memory bandwidth" measurementfrom event counters -

1. Intel Core 2 Duo processor:

Memory Bandwidth =
(64 * BUS_TRANS_MEM.ALL_AGENTS * CPU Frequency) / CPU_CLK_UNHALTED.CORE

2. Intel Core i7 processors:

Please see this article

Neil,

there are two blogs on ISN related to your question: "Memory management challenges in parallel applications" (Windows-specific) and "Is your memory management multi-core ready?" (Linux-specific).

I hope this info helps you.
