Abstract: In various embodiments, methods and systems for implementing hash-based partitioning in distributed computing systems are provided. At a high level, a distributed computing system having an underlying range-based partitioning architecture for storage may be configured as a hash-based partitioning system, for example, a hybrid range-hash table storage. An operations engine of the hash-based partitioning system receives a tenant request to provision input/output operations per second (IOPS). The tenant request comprises a requested number of IOPS. Based on the tenant request, a provisioning operation to provision IOPS in a hybrid range-hash table storage with hash-based partitioning is determined. The provisioning operation is selected from one of the following: a table creation provisioning operation, an IOPS increase provisioning operation, and an IOPS decrease provisioning operation. The selected provisioning operation is executed for a corresponding table.

Abstract: A method prepares a computer program for operation in a computer supply system that supplies portions, or program units, of program code or program data of the computer program as the program needs the portions. The method includes defining a program unit of the program and removing the program unit from the program, thereby producing a program skeleton that is missing the program unit. The method further includes inserting instructions in place of the program unit in the program skeleton. The instructions are operative to request the program unit when the program skeleton encounters the instructions. An information structure includes a program skeleton of a program. The program skeleton is missing a funclet of the program, but includes a placeholder in place of the funclet. The program skeleton additionally includes instructions in place of the funclet. The instructions are operative to request the funclet when the program skeleton encounters the instructions.

Abstract: A method for providing energy to a building using utility-compatible distributed generation equipment. In accordance with the method, a building owner leases space in a building to an energy provider. The energy provider installs or has installed utility-compatible distributed generation equipment in the leased space at no capital cost to the building owner, wherein the distributed generation equipment is capable of providing electric energy or both electric and thermal energy to the building. The energy provider also installs or has installed a gas delivery system that is capable of delivering natural gas from a gas utility interface to the distributed generation equipment in a manner that meets the gas pressure and volume requirements of the distributed generation equipment. The building owner uses the energy provided by the distributed generation equipment on a first use basis.

Abstract: A method of supplying program units of a computer program as the program needs the program units includes running a program skeleton. The program skeleton is derived from the program, but has a program stub where a program unit associated with the program stub may be inserted. Upon encountering the program stub, the method includes getting the program unit associated with the program stub and inserting the program unit at the program stub. A method of supplying funclets of a computer program from a server computer system to a client computer system includes receiving a plurality of requests for funclets during a test period. If a tested probability of requests for a first funclet being followed by requests for a second funclet is at least a predetermined probability, then the method also includes sending the first funclet and the second funclet to the client computer system in response to a request from the client computer system for the first funclet after the test period.

Abstract: Each component binary in a heterogeneous program is translated from a platform-specific instruction set into a set of intermediate representation (IR) instructions that are platform-neutral. The IR instructions are grouped into IR code blocks, the IR code blocks into IR procedures, and the IR procedures into IR components to create an intermediate representation hierarchy for the program. An application program interface is provided that permits user access to the IR hierarchy for instrumentation, optimization, navigation, and manipulation of the IR hierarchy. The transformed IR hierarchy is then translated into platform-specific instructions and output as a modified binary. The user can designate a different platform for the output translation of a code block than the platform for which the code block was originally written. Prologue and epilog code is added to contiguous blocks that are translated into different architectures.

Abstract: Described is a system and method for dynamically modifying an executing heterogeneous program in a heterogeneous distributed computing environment. A system reference is obtained to a target system on which the heterogeneous program is executing. The target system may be a local or a remote system. Based on the system reference, a program reference associated with the program is obtained which is used to locate a component of the program. An executable code associated with the component is modified to create a modified executable code based on a modification of an internal representation of the component. The modified code is inserted into the target system memory without requiring the target system to go offline. The code is inserted either by patching over an original memory area or injecting into a new memory location. The code may be inserted when the target program is operating in user mode or kernel mode.
