A technique for managing an object in memory is disclosed. The technique comprises: assigning the object to an assigned frame wherein the object can be released when the assigned frame is released; detecting an attempt to place a reference to the object in an older frame, the older frame being older than the assigned frame; and reassigning the object to a reassignment frame that is at least as old as the older frame.

A method, system, and computer program product for managing a heap of memory allocated to a program being executed on a data processing system is disclosed. A limited amount of memory is allocated to a program being executed by a mutator on a data processing system. The memory comprises memory objects. The disclosed method identifies memory objects, which are allocated to the program but are not referenced anymore. These dead memory objects are freed and made available for further allocation in the program. The memory objects that are still referenced are organized in compact contiguous blocks. Thus, the disclosed method recycles memory allocated to the program. The disclosed method is executed iteratively and concurrently with the execution of the program. The disclosed method does not interfere with program execution. Amount of memory required is specified before the commencement of the disclosed method and the same amount is freed without any surplus.

Providing data to an application running on a segmented virtual machine (VM) is disclosed. Providing data includes opening an interface between the segmented VM and an external data source, transferring data from the external data source to an interface buffer, transferring a first selected amount of data from the interface buffer to a shell VM buffer, transferring a second selected amount of data from the shell VM buffer to a core VM buffer, and providing portions of the data from the core VM buffer to the application in response to read requests from the application.

A computer system includes a memory and a processor coupled with the memory, configured to assign to each of a plurality of processes a corresponding amount of committed memory from a memory pool, the memory pool including committed memory and uncommitted memory; and dynamically allocate an additional amount of memory required by one of the plurality of processes from the uncommitted memory in the memory pool. Managing memory includes assigning to each of a plurality of processes a corresponding amount of committed memory from a memory pool, the memory pool including committed memory and uncommitted memory; and dynamically allocating an additional amount of memory required by one of the plurality of processes from the uncommitted memory in the memory pool.

A technique is disclosed for redirecting information in a segmented virtual machine. The technique includes sending information to a shell VM and redirecting the information to bypass the shell VM. A technique for evaluating whether to redirect information may include sending a discovery packet, receiving a reply to the discovery packet; and determining whether a switch is capable of stitching based on the reply. A technique for responding to a discovery packet may include receiving the discovery packet at a switch and sending a response indicating a capability of the switch.

Managing memory comprises execute a mutator comprising a plurality of mutator threads, and concurrently execute a garbage collector. Each of the plurality of mutator threads is separately stopped and notified, and is interrupted at a respective safepoint. In some cases executing the garbage collector includes remapping one or more references to one or more objects in an existing from-space, releasing the existing from-space, relocating one or more live objects that currently reside in a new from-space to one or more corresponding new locations, and identifying a set of one or more candidate pages suitable for forming next from-space during next garbage collection iteration.
