What Is High-Performance Computing?

High-Performance Computing runs advanced applications parallelly, effectively, and quickly.

Some of you must think parallel computing and high-performance computing are the same. They are related, but they have some differences. 

Parallel computing is executing multiple tasks simultaneously by dividing them into smaller subtasks that can be processed independently. It involves concurrently using multiple processors or cores to perform computations, thereby speeding up the overall processing time. 

On the other hand, high-performance computing (HPC) uses advanced computing techniques, technologies and architectures to solve complex problems efficiently and quickly. HPC systems are designed to deliver exceptional computational performance, typically using a combination of parallel computing, advanced hardware infrastructure, and optimized software.

Suppose you have to process a 100 TB file. Could a centralized machine be able to process it? The answer is no. So, in that case, you need a distributed system where different machines are running to work on advanced applications using advanced architectures and technologies. And here, high-performance computing comes in.

Real-life Analogy of High-Performance Computing

Imagine you are a chef working in a restaurant, responsible for preparing multiple dishes simultaneously to satisfy the hungry patrons. You have a standard kitchen with a limited number of burners on the stove and a single oven. As the orders arrive, you quickly realize that your current setup cannot meet the demand. 

This is where high-performance computing (HPC) comes into play. High-performance computing (HPC) is like a state-of-the-art professional kitchen with multiple burners, ovens, and a skilled team of sous chefs. Just as the upgraded kitchen enables chefs to handle larger orders efficiently, HPC empowers researchers and businesses to process massive amounts of data and perform complex calculations with remarkable speed and efficiency. Similar to parallel cooking and precise temperature control.

High-Performance Computing Architecture 

Construction 

To set up an effective and high-quality application architecture, servers should be connected to nodes/clusters in a network. Software programs and algorithms run simultaneously on the server. The cluster is connected to a data storage server to save the output. An HPC system consists of various nodes/clusters that perform specific operations. 

Cluster- An HPC cluster consists of several types of computer servers. Each server is called a “node”. Nodes within each cluster are interconnected within the server to increase processing speed. In simple terms, a node is a device which is doing the processing.

Processing Units

The central processing units (CPUs) in HPC systems are more powerful than standard desktop computers. They contain thousands of processing cores that can operate simultaneously. Some HPC systems also incorporate graphics processing units (GPUs) and field-programmable gate arrays (FPGAs) as accelerators to handle certain calculations more efficiently.

Storage

HPC storage systems are optimized for speed and bandwidth. They use solid-state drives (SSDs), burst buffers, and parallel file systems like Luster and GPFS to quickly access, store, and retrieve data. Some HPC storage is also tiered, with faster storage for more frequently accessed data and slower storage for less used data.

Software

HPC systems run specialized software like a message-passing interface (MPI) to coordinate processes across nodes and libraries like BLAS, LAPACK, and ScaLAPACK for linear algebra and matrix operations. Cluster management software is also used to monitor system health, deploy software, and schedule jobs.

While HPC systems come in many shapes and sizes, they share some common components focused on maximizing performance for highly complex computing. Continued innovation in processing power, interconnects, storage, and software helps fuel discoveries that shape our future.

Scheduling

1. Job Submission: Users submit their computational tasks to the HPC system, providing job details and requirements.
2. Resource Selection: The scheduler selects suitable computing resources based on job requirements, availability, and system policies.
3. Resource Allocation: The scheduler assigns allocated resources to each job, ensuring they meet the job’s needs and maximize resource utilization.
4. Job Execution: Jobs begin computation on the allocated resources, using parallel processing if applicable.

Cloud Infrastructure

Cloud computing providers offer a robust infrastructure that includes virtualized servers, storage resources, and networking capabilities. These resources are distributed across multiple data centres, providing high availability and fault tolerance.

Cloud orchestration tools like Apache Hadoop, Apache Spark, or Kubernetes help manage the deployment, monitoring, and scaling of HPC applications in the cloud environment. These tools automate resource provisioning, workload scheduling, and monitoring, optimizing overall system performance.

Types of cloud

1. Private Cloud: A private cloud is dedicated to a single organization, offering exclusive use of computing resources. It is built and managed within the organization’s data centre or hosted by a third-party service provider. 
2. Public Cloud: A public cloud is operated and managed by a third-party cloud service provider, making computing resources available to multiple organizations or individuals over the Internet. 
3. Hybrid Cloud: A hybrid cloud combines private and public cloud environments, allowing organizations to leverage both benefits. It enables the seamless integration of resources and applications across private and public clouds.
