摘要： Illustrative embodiments include a method, system, and computer program product for estimating boot-time memory requirement of a data processing system. A data processing system identifies, using system configuration information associated with the data processing system, a set of components needed for booting up the data processing system. The data processing system determines a dependency of a component identified in the set of components, the component including a memory estimator program. The data processing system determines an ancestry of the component identified in the set of components. The data processing system receives, using the memory estimator program of the component, a boot-time memory requirement of the component. The data processing system calculates a total boot-time memory requirement. The data processing system determines whether an amount of real memory of the data processing system satisfies the total boot-time memory requirement.

摘要： An I/O request to store a file in a file-system is received. A determination is made whether the size of the file does not exceed a threshold size. Exceeding the threshold results in storing at least a portion of the file in a block of the file-system devoid of sub-blocks. A determination is made whether the size of the file does not exceed a size of unallocated space within a single block in the file-system. The single block includes a set of sub-blocks. Responsive to the size of the file not exceeding the threshold size and the size of unallocated space within the single block, the file is stored, at an address, in a first subset of the set of the sub-blocks of the single block. The address identifies the single block and a position of a sub-block in the subset.

摘要： A computer identifies a relationship among a subset of a set of data blocks, a basis of the relationship forming a context shared by the subset of data blocks. The computer selects a code data structure from a set of code data structures using the context. The context is associated with the code data structure, and the code data structure includes a set of codes. The computer computes, for a first data block in the subset of data blocks, a first code corresponding to a content of the first data block. The computer determines whether the first code matches a stored code in the code data structure. The computer replaces, responsive to the first code matching the stored code, the first data block with a reference to an instance of the first data block. The computer causes the reference to be stored in a target data processing system.

摘要： A system and method for extending the use of the cross-memory descriptor in a server partition environment such that it may be used to describe another partition's memory, e.g., a client partition's memory (referred to hereafter as a “remote” memory), are provided. With the system and method, when an operating system in a logically partitioned computing system is initialized, operating system kernel services are invoked that examine a device tree of the computing system and generate an extended cross-memory descriptor that describes the local memory of another logical partition, which is a remote memory to the present logical partition. When an access to a remote memory is required to perform an operation, the operating system of the server partition uses the stored extended cross-memory descriptor to perform the remote memory access.

摘要： Provided are techniques for the tracing of computer processes and, more specifically, to techniques that enable a work unit to be traced across multiple processing components. A data structure is created and associated with a work unit. The first time a unit of work is processed a tracing context is retrieved form a pool and associated with the data structure. As the unit of work is passed from component to component, the data structure is passed so that each component has access and is able to augment the same tracing context associated with the unit of work.

摘要： A method, system, and computer program product for fast cancellation of an I/O request in a data processing system are provided in the illustrative embodiments. A first component in a stack comprising a plurality of components determines whether a memory buffer associated with the I/O request is valid, the memory buffer being an addressable area in a memory in the data processing system. The first component, responsive to the memory buffer being valid, creates a first request data structure corresponding to the I/O request, wherein the first request data structure includes a reference to the memory buffer. The first component passes the first request data structure to a second component in the stack.
