摘要： Embodiments of the invention provide techniques for scheduling jobs on a multi-node computing system based on the predicted environmental impact of executing the jobs. In one embodiment, a plurality of job plans may be generated for processing a requested job on the multi-node computing system. The environmental impacts resulting from executing each job plan may be estimated by matching the job plans to stored data based on standardized executions of job plans. Further, environmental impacts may be estimated by matching the job plans to stored data based on actual environmental measurements obtained during prior executions of the job plan on the multi-node computer system. The job may be executed using a job plan selected based on predicted environmental impacts and time performance.

摘要： Techniques are disclosed for backing up and/or restoring data. In one embodiment, a request is received to back up at least a first unit of data stored in a database. Upon determining that the first unit of data is at least partially derived from a second unit of data stored in the database, a backup may be generated that includes less than all of the first unit of data. Subsequently, the first unit of data may be fully restored from the backup.

摘要： A method and apparatus creates and manages persistent memory (PM) in a multi-node computing system. A PM Manager in the service node creates and manages pools of nodes with various sizes of PM. A node manager uses the pools of nodes to load applications to the nodes according to the size of the available PM. The PM Manager can dynamically adjust the size of the PM according to the needs of the applications based on historical use or as determined by a system administrator. The PM Manager works with an operating system kernel on the nodes to provide persistent memory for application data and system metadata. The PM Manager uses the persistent memory to load applications to preserve data from one application to the next. Also, the data preserved in persistent memory may be system metadata such as file system data that will be available to subsequent applications.

摘要： A method and apparatus optimizes job and data distribution on a multi-node computing system. A job scheduler distributes jobs and data to compute nodes according to priority and other resource attributes to ensure the most critical work is done on the nodes that are quickest to access and with less possibility of node communication failure. In a tree network configuration, the job scheduler distributes critical jobs and data to compute nodes that are located closest to the I/O nodes. Other resource attributes include network utilization, constant data state, and class routing.

摘要： Embodiments off the invention provide a mechanism for process migration on a massively parallel computer system. In particular, embodiments of the invention may be used to update process state data for a migrated compute node, such as MPI (or other communication library) state data, across a full collection of compute nodes present in a given parallel system executing a parallel task. Migrating a process form one compute node to another may be useful to address a variety of sub-optimal operating conditions. For example, one or more processes may be migrated to cure network congestion resulting from a poorly mapped task or when a compute node is predicted to experience a hardware failure.

摘要： Methods, systems, and products are disclosed for executing a distributed Java application on a plurality of compute nodes. The Java application includes a plurality of jobs distributed among the plurality of compute nodes. The plurality of compute nodes are connected together for data communications through a data communication network. Each of the plurality of compute nodes has installed upon it a Java Virtual Machine (‘JVM’) capable of supporting at least one job of the Java application. Executing a distributed Java application on a plurality of compute nodes includes: tracking, by an application manager, a just-in-time (‘JIT’) compilation history for the JVMs installed on the plurality of compute nodes; and configuring, by the application manager, the plurality of jobs for execution on the plurality of compute nodes in dependence upon the JIT compilation history for the JVMs installed on the plurality of compute nodes.

摘要： A process is disclosed for identifying and recovering from resource leaks on compute nodes of a parallel computing system. A resource monitor stores information about system resources available on a compute node in a clean state. After the compute node runs a job, the resource monitor compares the current resource availability to the clean state. If a resource leak is found, the resource monitor contacts a global resource manger to remove the resource leak.

摘要： The disclosure herein provides data security on a parallel computer system using virtual private networks connecting the nodes of the system. A mechanism sets up access control data in the nodes that describes a number of security classes. Each security class is associated with a virtual network. Each user on the system is associated with one of the security classes. Each database object to be protected is given an attribute of a security class. Database objects are loaded into the system nodes that match the security class of the database object. When a query executes on the system, the query is sent to a particular class or set of classes such that the query is only seen by those nodes that are authorized by the equivalent security class. In this way, the network is used to isolate data from users that do not have proper authorization to access the data.
