In computing, a memory address is a reference to a specific memory location in memory used by both software and hardware Pgas is typified by communication operations involving a global memory address space abstraction that is logically partitioned, where a portion is local to each process, thread, or processing element Address generation unit intel's nehalem microarchitecture contains multiple agus behind the cpu's reservation station

The address generation unit (agu), sometimes also called address computation unit (acu), [1] is an execution unit inside central processing units (cpus) that calculates addresses used by the cpu to access main memory.
Addressing modes are an aspect of the instruction set architecture in most central processing unit (cpu) designs
Addressing modes define how the machine language instructions in that architecture identify the operand (s) of each instruction An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants. When a larger block is split, it is divided into two smaller blocks, and each smaller block becomes a unique buddy to the other. Data structure alignment is the way data is arranged and accessed in computer memory
It consists of three separate but related issues Data alignment, data structure padding, and packing The cpu in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned, which generally means that the data's memory address is a multiple of the data. Memory address register in a computer, the memory address register (mar) [1] is the cpu register that either stores the memory address from which data will be fetched to the cpu registers, or the address to which data will be sent and stored via system bus.
In computer science, partitioned global address space (pgas) is a parallel programming model paradigm
