Abstract: The present disclosure relates to systems, methods, and computer-readable media for utilizing a new memory allocation function library called PmemMalloc. For example, the PmemMalloc library allocates pre-allocated, partitioned, and fixed shared memory blocks. In addition, by utilizing the PmemMalloc library, the memory allocation system described herein overcomes problems with persistence and enumeration that encumber existing malloc libraries. Indeed, the PmemMalloc library enables the memory allocation system to perform servicing computation in parallel across multiple CPU cores/threads, distribute computation equally among threads, prioritize servicing, among other improvements. Notably, the PmemMalloc library provides major constructs (e.g., persistence, enumeration, and debuggability) not available existing malloc libraries.

Abstract: Described herein is a system and method for overlapping migration to another host node with a customer request to stop or reboot a virtual machine. A customer request is intercepted. Determination whether or not migration of the virtual machine on the source host node is capable of being performed. When the migration of the virtual machine on the source host node is capable of being performed, the virtual machine is stopped on the source host node, and, the virtual machine is migrated to an updated host node. When the customer request is a stop of the virtual machine, the virtual machine is stopped on the updated host node. When the customer request is a reboot of the virtual machine, the virtual machine is rebooted on the updated host node.
