Mapping memory allocation requests using various memory attributes

A computer program product comprising a non-transitory computer readable storage device having program instructions embodied therewith, the program instructions readable and executable by a computer to perform a method comprising:

• receiving requested memory buffer attributes that describe memory buffer attributes needed for various processes, wherein the requested memory buffer attributes are received from a kernel of an operating system, wherein the requested memory buffer attributes describe bandwidth, density, probable rate of memory failure, and logic within the memory buffer for performing logic processing on the device without use of a central processing unit;
• storing the requested memory buffer attributes in a virtual memory representation, wherein the virtual memory representation describes various types of memories used by a system;
• storing data on an appropriate memory device used by the system based on a standing memory policy that identifies a type of memory that is used with a certain type of application, wherein the appropriate memory device is a memory device that is used with the certain type of application;
• finding, by the kernel of the operating system, the appropriate memory device, wherein the appropriate memory device has the requested memory buffer attributes;
• receiving a page fault, wherein the page fault is based on the data being called by a process but not being currently mapped by a memory management unit (MMU) into a virtual address space of the process;
• and
• in response to receiving the page fault, retrieving and returning the data stored on the appropriate memory device in order to address the page fault.

A computer system comprising one or more processors, one or more computer readable memories, and one or more computer readable non-transitory storage mediums, and program instructions stored on at least one of the one or more computer readable non-transitory storage mediums for execution by at least one of the one or more processors via at least one of the one or more computer readable memories, the stored program instructions executed to perform a method comprising:

• receiving user requested memory buffer attributes that describe memory buffer attributes needed for various processes, wherein the user requested memory buffer attributes are received from a kernel of an operating system, and wherein the user requested memory buffer attributes describe bandwidth, density, probable rate of memory failure, and logic within the memory buffer for performing logic processing on the device without use of a central processing unit;
• storing the user requested memory buffer attributes in a virtual memory representation, wherein the virtual memory representation describes various types of memories used by a system;
• storing data on an appropriate memory device used by the system based on standing memory policy that identifies a type of memory that is used with a certain type of application, wherein the appropriate memory device is a memory device that is used with the certain type of application;
• finding, by the kernel of the operating system, the appropriate memory device, wherein the appropriate memory device has the user requested memory buffer attributes;
• receiving a page fault, wherein the page fault is based on the data being called by a process but not being currently mapped by a memory management unit (MMU) into a virtual address space of the process;
• and
• in response to receiving the page fault, retrieving and returning the data stored on the appropriate memory device in order to address the page fault.
