How to avoid heap fragmentation?

Question

I\'m currently working on a project for medical image processing, that needs a huge amount of memory. Is there anything I can do to avoid heap fragmentation and to speed up

Answer 1

Without much more information about the problem (for example language), one thing you can do is to avoid allocation churn by reusing allocations and not allocate, operate and free. Allocator such as dlmalloc handles fragmentation better than Win32 heaps.
