 | | It is tentatively concluded that this approximation is untenable for main memory, especially under working set policies; and that the linearity of the data for the drum reflects the behavior of the Multics scheduler for background jobs, not the behavior of programs. | | | In the late spring and early summer of 1964 it became obvious that greater facility in the computing system was required if time-sharing techniques were to move from the state of an interesting pilot experiment into that of a useful prototype for remote access computer systems. | | | The system includes particular features for creating instructional software, and in that application it is intended for direct use by teachers or other persons whose expertise lies in the subject matter being addressed, but not necessarily in computer programming. |

| | CSE 262: Notes for Lecture 11 (2/12/02) |
| | Each processor can directly access remote (non-local) memory, though it must explicitly designate which processor's memory it will access (with true shared memory, such mapping is handled transparently by the hardware.) We call this type of communication "one-sided," since only one processor needs to be involved in the communication. | | | In a shared memory parallel computer all processors have direct access to all of memory. | | | As a result, memory access times are non-uniform; a processor sees different access times to memory, depending on whether the access is local or not, and if not, on the distance to the target memory. |

| | An Overview of MPP Systems |
| | Memory associated to processors in such a way is called local memory from the viewpoint of that processor because it has direct access to that node's memory ports and need not go through any memory network routing. | | | Non Uniform Memory Access systems are those systems in which memory access times are not uniform, but rather dependent on the route to and latency at the node containing the requested memory line. | | | In the NUMA architecture, the memory was distributed among the various processor nodes and memory accesses to the local memory would happen faster than accesses that had to go to memory stored on a remote processor node. |

| | RDMA (Remote Direct Memory Access) is a concept whereby two or more computers communicate via DMA directly from main memory of one system to the main memory of another. | | | DMA (Direct Memory Access) allows certain hardware subsystems within a computer to access system memory for reading and/or writing independently of the main CPU. | | | It allows the pixel information to be written into its video memory using a very simple interface, while it is alone responsible for generating the required signals for displaying the pixel information on a VGA monitor. |
