摘要： A system for managing storage of data units includes a data storage system configured to store multiple data blocks, at least some of the data blocks containing multiple data units, with at least a group of the data blocks being stored contiguously, thereby supporting a first read operation that retrieves data units from at least two adjacent data blocks in the group. The system is configured to perform one or more operations with respect to data units, the operations including a delete operation that replaces a first data block containing a data unit to be deleted with a second data block that does not contain the deleted data unit, with the second data block having the same size as the first data block.

摘要： A method for performing a distributed computation on a computing system using computational resources dynamically allocated using a computational resource manager includes storing information specifying quantities of computational resources associated with respective ones of a number of program portions of the program, where the program portions perform successive transformations of data and each program portion uses computational resources granted by the computational resource manager enabling computation associated with that program portion to be performed in the computing system, requesting a first quantity of computational resources associated with a first program portion of the number of program portions from the computational resource manager, receiving a second quantity of computational resources from the computational resource manager, less than the requested first quantity of computational resources, performing computation associated with the first portion of the program using the second quantity of computational resources, while performing the computation associated with the first portion of the program using the second quantity of computational resources, receiving an additional quantity of computational resources from the computational resource manager, and performing an additional computation associated with the first portion of the program using the additional quantity of computational resources while performing the computation associated with the first portion using the second quantity of computational resources.

The system is configured to perform two or more operations with respect to data units. The operations include: a second read operation, different from the first read operation, that retrieves a data unit to be read based at least in part on an address of a data block containing the data unit to be read, and a delete operation that replaces a first data block containing a data unit to be deleted with a second data block that does not contain the deleted data unit.

摘要： A system for managing storage of data units includes a data storage system configured to store multiple data blocks, at least some of the data blocks containing multiple data units, and configured to store, for at least some of the data blocks, corresponding historical information about prior removal of one or more data units from that data block, the removal affecting at least some addresses of data units in that data block. The system is configured to perform at least one operation that accesses at least a first data unit stored in a first data block according to address information interpreted based on any stored historical information corresponding to the first data block.

摘要： Requesting computational resources for executing a program including a number of program portions includes computing sets of requests. Each set, except an initial set, is processed by a computational resource manager only if the previously submitted sets were granted. One or more additional sets are formed for processing by the manager after the initial set. A request of the additional sets includes a partial request for a program portion that is in a least-fulfilled set of program portions. Each program portion is associated with a respective fulfillment ratio of its quantity of previously requested resources divided by an associated target quantity. The partial request requests a quantity of resources that is small enough so that, after the partial request is granted, each program portion in the least-fulfilled set will have a fulfillment ratio that is greater than its fulfillment ratio had been, and is still smaller than one.
