IPP memory functions

zxs — Wed, 07 Jul 2004 23:24:17 GMT

Can you give some details about IPP dynamic memory allocation functions? Do you have your own optimized heap implementation, or it is just a wrapper for existing Operating System's malloc() that ensures proper alignment?

It's well known that, for example, default Visual C++ heap manager is not any good in multithreaded environment, especially on SMP systems.

Looks at the following benchmarks:
http://www.microquill.com/smartheapsmp/index.html
http://www.winheap.com/winheap_info/benchmarks.php

It would be great if IPP provided decent heap manager of its own.

You could base it on one of the free libraries (not sure on license terms) such as:
http://www.cs.umass.edu/~emery/hoard/
http://gee.cs.oswego.edu/dl/html/malloc.html
And make it configurable so that the IPP users could select the best heap implementation for their application.

Hi,

currently we have just wrappers for C run time malloc/free, with adding allocation of aligned memory blocks. Thank you for information and suggestion, we will consider that.

Regards,

Vladimir

I request thatyou also consider including a memory pooling policy in addition or as an adjunt to a more optimal allocation approach. Memory poolingis a requirement when doing continuousimage processing on video.

Thanks,

Phil

Hi, what do you mean under pooling of memory?
