What is SMP and MPP?

What is SMP and MPP?

SMP stands for Symmetric Multi processor. MPP stands for Massive parallel Processing. 2. In SMP every processor share a single copy of the operating system (OS) In MPP each processor use its own operating system (OS) and memory.


NUMA is similar to SMP, in which multiple CPUs share a single memory. However, in SMP, all CPUs access a common memory at the same speed. As a result, NUMA architecture scales much better to higher numbers of CPUs than SMP.

What is SMP architecture?

Symmetrical multiprocessing (SMP) is a parallel computer architecture in which multiple processors run a single copy of the operating system and share the memory and other resources of one computer. In most SMP systems, each processor has its own cache memory.

What is SMP database?

Symmetric Multi-Processing (SMP) is a tightly coupled multiprocessor system where processors share resources – single instances of the Operating System (OS), memory, I/O devices and connected using a common bus.

Is Hadoop a MPP?

And as Hadoop became more and more popular, MPP databases entered their descent….Hadoop vs MPP.

MPP Hadoop
Target Systems General DWH and analytical systems Purpose-built data processing engines

What are MPP databases?

An MPP database is a data warehouse or type of database where processing is split among servers or nodes. A leader node handles communication with each of the individual nodes. The computer nodes carry out the process requested by dividing up the work into units and more manageable tasks.

What is NUMA boundary?

Under NUMA, a processor can access its own local memory faster than non-local memory, that is, memory local to another processor or memory shared between processors.” This means that memory is commonly “partitioned” at the hardware level in order to provide each processor in a multi-CPU system with its own memory.

What is a NUMA system?

NUMA systems are advanced server platforms with more than one system bus. They can harness large numbers of processors in a single system image with superior price to performance ratios. NUMA is an alternative approach that links several small, cost-effective nodes using a high-performance connection.

What is a NUMA domain?

Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. NUMA architectures logically follow in scaling from symmetric multiprocessing (SMP) architectures.

How does SMP implemented?

Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system …

What is a MPP database?

Is Cassandra a MPP database?

Row store means that like relational databases, Cassandra organizes data by rows and columns. It is a massively parallel processing (MPP) database server with an architecture specially designed to manage large-scale analytic data warehouses and business intelligence workloads.
