CRAK: Linux Checkpoint/Restart As a Kernel Module
Process checkpoint/restart is a very useful technology for process migration, load balancing, crash recovery, rollback transaction, job controlling and many other purposes. Although process migration has not yet been widely used and is not widely available commercial systems, the growing shift of computing facilities from supercomputers to networked workstations and distributed systems is incre...
متن کاملUnix to LinUx Migration
This paper aims to show the benefits of choosing Linux and migrating existing UNIX environments to the Linux platform. This applies in particular to migrations from RISC-based platforms. It also shows the extent to which Linux is now a trusted, mainstream platform and how any technical risks associated with migrations can be mitigated. This paper addresses a technical audience.
متن کاملMPVM: A Migration Transparent Version of PVM
Parallel Virtual Machine (PVM) is a widely-used software system that allows a heterogeneous set of parallel and serial UNIX-based computers to be programmed as a single message-passing parallel machine. In this paper, an extension to PVM to support dynamic process migration is presented. Support for migration is important in general-purpose workstation environments since it allows parallel comp...
متن کاملProcess vs. Task Migration
This paper describes task and process migration for the OSFII AD Operating System (OS) server for massively parullel processors and clusters of workstations. OSFII AD runs in user space, on top of the Mach microkernel. A process in the OSFII AD server is composed of a Mach task state (memory, capabilities, threads, etc.) and of the UNIX-related state (open file descriptors, signal masks, etc.)....
متن کاملUsenix Winter Conference San Francisco, California. 1992 SUPPORTING CHECKPOINTING AND PROCESS MIGRATION OUTSIDE THE UNIX KERNEL
We have implemented both checkpointing and migration of processes under UNIX as a part of the Condor package. Checkpointing, remote execution, and process migration are different, but closely related ideas; the relationship between these ideas is explored. A unique feature of the Condor implementation of these items is that they are accomplished entirely at user level. Costs and benefits of imp...
