Abstract: Persistent data storage is provided by a method that includes receiving a low latency store command that includes write data. The write data is written to a first memory device that is implemented by a nonvolatile solid-state memory technology characterized by a first access speed. It is acknowledged that the write data has been successfully written to the first memory device. The write data is written to a second memory device that is implemented by a volatile memory technology. At least a portion of the data in the first memory device is written to a third memory device when a predetermined amount of data has been accumulated in the first memory device. The third memory device is implemented by a nonvolatile solid-state memory technology characterized by a second access speed that is slower than the first access speed.

Abstract: Disclosed are a method of and system for creating a load balanced spatial partitioning of a structured, diffusing system of particles with pairwise interactions that is scalable to a very large number of nodes and has favorable communications characteristics including well defined bounds on the number of hops and the number of nodes to which a particle's position must be sent. To deal with structural imbalance, we can assign a weight corresponding to the computational cost for a particular pair interaction of particles or locally clustered groups of particles to simulation space at the midpoint of the distance between the particles or centers of the clusters. We then carry out a spatial partitioning of the simulation volume using a k-d tree or optimal recursive bisection (ORB) to divide the volume into sections that have approximately equal total weights. To deal with local degradation of the load balance caused by changes in the distribution of particles from that used to determine the original spatial decomposition one can assign the actual computation of the pair interaction between two particles to any node that has the positions of both particles.

Abstract: Method and system for managing process scheduling among multiple control contexts within a data processing environment. A given control context, comprising one of multiple control contexts, is assumed to be executing at a processing node within the environment. The approach includes processing a scheduling event; evaluating process scheduling from within the executing control context to determine a restart control context, which also comprises one of the multiple control contexts; and restarting executing data within the restart control context in response to the process scheduling occurring within the given control context. Context switching is employed only if process scheduling determines that the restart control context is other than the given control context. The technique is particularly useful in nonpreemptive parallel data processing environments.
