Dynamic Shared memory NVIDIA Developer Forums
Memory-mapped files can be shared across multiple processes. Processes can map to the same memory-mapped file by using a common name that is assigned by the process that created the file. Processes can map to the same memory-mapped file by using a common name that is assigned by the process that created the file....

Load file into shared memory using IPC C / C++
Shared memory is the fastest interprocess communication mechanism. The operating system maps a memory segment in the address space of several processes, so that several processes can read and write in that memory segment without calling operating system functions.... It is trivial to make a C++ server that creates the shared memory. It is more interesting to make a Java server. Let's still call it JServer. In your JServer, you need someway similar to the following, to cache the raw pointers return from the native code.
Patterns for Programming Shared Memory
Memory-mapped files are accessed through the operating system’s memory manager, so the file is automatically partitioned into a number of pages and accessed as needed. You do not have to handle the memory management yourself. how to find history on computer 9/03/2010 · I think very little of your problem has to do with shared memory, per se, just some missing understanding of the use of arrays and pointers in the C language.
