They typically take up A LOT of space.
Supercomputers have the following disadvantages:
- Generate a lot of heat often require water cooling in addition to an A/C system
- High power requirements which cost at minimum $400 per hour or $3.5 million per year as an example
- The initial purchase can be at minimum $100,000
- Large space requirements
The main Disadvantage of parallel connection is that it uses more hardware resources for example if you want to communicate between two system using parallel connection than it requires more numbers of connection between those two systems.It requires redundant hardware.
Using parallel computing will save time and money, solve large or very complex problems with more ease. It even allows you do do more than one thing at a time which increases your productivity.
the main disadvantages of parallel computing is in this process want highly processors for speed processing.

"Distributed" or "grid" computing in general is a special type of parallel computing, it is advanced in the means of using distributed computing.
EPIC, which stands for Explicitly Parallel Instruction Computing.
Amiga Computing was created in 1988.

One advantage to parallel computing is the ability to process information quicker. A disadvantage is maintaining the system because it is complex.

Parallel computing and distributed computing are ways of exploiting parallelism in computing to achieve higher performance. Multiple processing elements are used to solve a problem, either to have it done faster or to have a larger size problem been solved. To state simply, if the processing elements share the memory, it is called parallel computing, other wise it is called distributed computing. Some have opinion that distributed computing is a special form of parallel computing.
The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.
EPIC, which stands for Explicitly Parallel Instruction Computing.
supercomputers allows both parallel and distributed computing
The cost optimal algorithm in parallel computing is the modular structured parallel algorithm that satisfy the insatiable demand of low power consumption, reduces speed and minimum silicon area.
Lots of processors all doing the same task simultaneously. For instance a graphics card will use massively parallel processing computing to render the display.

An advantage of cloud computing is to be able to access this product from multiple locations. A disadvantage is that cloud computing is harder to secure.
