Our product has a couple of new requirements that I have not come across before. 1) The first is the ability to completely segregate control data from allocated data. This makes the allocator more like a resource manager in that you allocate and mange the resource but have no access to it. The data structure design of jemalloc lends itself fairly well to meeting this requirement. 2) The second requirement is focused on multi-node NUMA systems. Consider the requirement to allocate memory on a specified node. A buffer is returned to the application on the requested node but the application then migrates the data to another node for processing. When the app frees the buffer, it is returned to the allocator’s free pool. The problem is the memory is now located on the wrong node. Subsequent allocations can result in misplaced data and performance anomalies. This behavior is true for any allocator; libc malloc(3), etc. Have these types of requirements been considered or solved by other systems? ThanksTerrell Convey Computer Systems</div></body></html>
