Difference Between High Performance Computing and High Throughput Computing

High-Performance Computing(HPC) is a computing technique to process computational problems, and complex data and to perform scientific simulations. HPC systems consist of considerably more number of processors or computer nodes, high-speed interconnects, and specialized libraries and tools. In order to use HPC systems effectively users must have a proper knowledge of parallel computing and optimization techniques. HPC is used in various fields such as engineering, finance, commercial applications, weather forecasting, and automotive design. 

Advantages of HPC

• Faster computation: HPC systems can process large and complex calculations and processes faster end efficiently than the traditional approach. 
• Scalability: HPC systems are more scalable because they can handle many processors and computing nodes according to their applications. 
• Parallel processing: HPC systems make use of parallel processing in order to divide the computations into smaller tasks so that they can be processed simultaneously. 
• Improved accuracy: HPC system performs and gives more accurate simulations and calculations. 

High Throughput Computing (HTC) is defined as a type of computing that aims to run a large number of computational tasks using resources in parallel. HTC systems consist of a distributed network of computers known as computing clusters. These systems are used to schedule a large number of jobs effectively. HTC majorly focuses on increasing the overall throughput of the system by running many smaller size tasks parallelly.  HTC is commonly used in scientific research and engineering applications in order to process large data sets or perform simulations that require extensive computational power.

Advantages of HTC

• Flexibility: HTC is more flexible and can be used for many computing tasks related to business analytics and scientific research. 
• Cost-Effectiveness: HTC is more cost-effective as compared to the solutions offered by High-Performance Computing(HTC) as it makes use of hardware and software that is available and less expensive and performs more tasks. 
• Reliability: HTC systems are mostly designed to provide high reliability and make sure that all tasks run efficiently even if any one of the individual components fails. 
• Resource Optimization: HTC also does proper resource allocation by ensuring that all the resources that are available are efficiently used and accordingly increases the value of computing resources that are available.
