    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: 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: Systems, methods, and software described herein provide accelerated input and output of data in a work process. In one example, a method of operating a support process within a computing system for providing accelerated input and output for a work process includes monitoring for a file mapping attempt initiated by the work process. The method further includes, in response to the file mapping attempt, identifying a first region in memory already allocated to a cache service, and associating the first region in memory with the work process.

    Abstract: Systems, methods, and software described herein allocate cache memory to job processes executing on a processing node. In one example, a method of allocating cache memory to a plurality of job process includes identifying the plurality of job processes executing on a processing node, and identifying a data object to be accessed by the plurality of job processes. The method further provides allocating a portion of the cache memory to each job process in the plurality of job processes and, for each job process in the plurality of job processes, identifying a segment of data from the data object, wherein the segment of data comprises a requested portion of data and a predicted portion of data. The method also includes providing the segments of data to the allocated portions of the cache memory.
