Abstract: Systems, methods, and software described herein facilitate accelerated input and output operations with respect to virtualized environments. In an implementation, a computing system passes a process identifier to a kernel driver for a host environment, wherein the process identifier identifies a guest process spawned in a virtual machine and wherein the kernel driver uses the process identifier to determine an allocation of host memory corresponding to guest memory for the guest process and returns the allocation of host memory. Additionally, the computing system performs a mapping of the allocation of host memory to an allocation of guest memory for the guest element.

Abstract: The technology disclosed herein enables optimized managing of cluster deployment on a plurality of host nodes. In a particular embodiment, a method includes defining parameters of a cluster for executing a process that will execute in a plurality of containers distributed across one or more of the plurality of host nodes. The method further provides adding a first container portion of the plurality of containers to a first host node portion of the plurality of host nodes. After adding the first container portion, the method includes determining that a remaining host node portion of the plurality of host nodes will not support more of the plurality of containers and adjusting the parameters of the cluster to allow the process to execute on the first host node portion.

Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media for managing data consumption rate in a virtual data processing environment. In a particular embodiment, a method provides, in a cache node of a host system, identifying read completions for one or more virtual machines instantiated in the host system, with the one or more virtual machines processing one or more processing jobs. The method further provides allocating the read completions to individual processing jobs of the one or more processing jobs and accumulating the read completions on a per-job basis, with the cache node determining a data consumption rate for each processing job of the one or more processing jobs.

Abstract: Systems, methods, and software described herein to provide data to large-scale processing framework (LSPF) nodes in LSPF clusters. In one example, a method to provide data includes receiving an access request from a LSPF node to access data in accordance with a version of a distributed file system. The method further includes, responsive to the access request, accessing the data for the LSPF node in accordance with a different version of the distributed file system, and presenting the data to the LSPF node in accordance with the version of the distributed file system used by the LSPF node.

Abstract: Systems, methods, and software described herein facilitate the allocation of large scale processing jobs to host computing systems. In one example, a method of operating an administration node to allocate processes to a plurality of host computing systems includes identifying a job process for a large scale processing environment (LSPE), and identifying a data repository associated with the job process. The method further includes obtaining data retrieval performance information related to the data repository and the host systems in the LSPE. The method also provides identifying a host system in the host systems for the job process based on the data retrieval performance information, and initiating a virtual node for the job process on the identified host system.

Abstract: Systems, methods, and software described herein facilitate interfacing between processing nodes and a plurality of data repositories. In one example, a method of interfacing between a processing node and a plurality of data repositories includes identifying, for the processing node, a data access request using a first data access format, wherein the data access request includes a data connector identifier. The method further includes translating the access request to a second data access format based on the data connector identifier, and identifying a data repository in the plurality of data repositories to service the data access request based on the data connector identifier. The method also provides accessing data for the data access request in the data repository via the second data access format.

Abstract: Described herein are systems, methods, and software to enhance the allocation of cache resources to virtual nodes. In one implementation, a configuration system in large-scale processing environment is configured to identify a request to initiate a large-scale processing framework (LSPF) cluster, wherein the LSPF cluster comprises a plurality of virtual nodes, and identify host computing resources of a host computing system allocated to each virtual node of the LSPF cluster. The configuration system further allocates cache memory of a cache service to each of the virtual nodes based on the host computing resources, and initiate the LSPF cluster in the computing environment.
