Allocating a large multidimensional vector causes memory "overshoot"

OpenCL clCreateContextFromType function results in memory leaks

QUESTION

Allocating a large multidimensional vector causes memory "overshoot"

Asked 2021-Aug-19 at 17:56

I observed an unexpected behavior when using a large multidmensional std::vector variable. In particular, when I allocate a 4-dimensional vector of large size, it can be seen, using a memory profiler, that my task shortly uses more memory than it would require for the variable.

An MWE to reproduce this behavior is the following:

This could be caused for different reasons, like returning without using smart-pointer (which could cause a copy).

But in your particular case, you pass something to F variable's constructor (no matter what), which takes additional memory till constructor returns.

Oh! yet another possible cause, an (un)intelligent vector implementation should reserve more than required (just in case, to speed up later appending).

QUESTION

OpenCL clCreateContextFromType function results in memory leaks

Asked 2020-Apr-11 at 20:11

I ran valgrind to one of my open-source OpenCL codes (https://github.com/fangq/mmc), and it detected a lot of memory leaks in the OpenCL host code. Most of those pointed back to the line where I created the context object using clCreateContextFromType.

I double checked all my OpenCL variables, command queues, kernels and programs, and made sure that they are all properly released, but still, when testing on sample programs, every call to the mmc_run_cl() function bumps up memory by 300MB-400MB and won't release at return.

you can reproduce the valgrind report by running the below commands in a terminal:

Well I still found one (tiny) memory leak in mmc code:
