High-Performance Computing Cluster

Over the last 15 years, High Performance Computing (HPC) has always been one of the fastest-growing IT markets with growth higher than the year-over-year growth of online games and tablets.

HPC is done primarily by using many processors or computers within a cluster and executed with the application of a parallel algorithm. By dividing tasks with large data into subsets based on certain rules, scientists are able to compute with different proces- sors or nodes within a cluster before eventually compiling the results with a significant reduction in computational time.

The applications of HPC systems are generally those large-scale computations beyond the reach of ordinary computers, including medical imaging, genetic analysis and comparison, computer animation, energy exploration, climate simulation, astronomy, space, and various  physical and chemical computations. The nodes of a HPC system work in parallel, i.e. they have to compute while processing tasks as well as exchange data with each other during processing. The performance of a HPC system is proportional to the scale of the given cluster. In contrast, the performance of a set of HPC systems is the sum of the processing capacities of the nodes within the given cluster.
High Performance Computing (HPC)
The applications of HPC systems are generally those large-scale computations beyond the reach of ordinary computers, including medi- cal imaging, genetic analysis and comparison, computer animation, energy exploration, climate simulation, astronomy, space, and various physical and chemical computations. The nodes of a HPC system work in parallel, i.e. they have to compute while processing tasks as well as exchange data with each other during rocessing. The performance of a HPC system is proportional to the scale of the given cluster. In contrast, the performance of a set of HPC systems is the sum of the processing capacities of the nodes within the given cluster. There are many classifications applicable to HPC systems, but typically they can fall into one of three types of classifications.
Symmetric Multi-Processing (SMP)
A system where all the CPUs are identical and share the same main memory is called Shared Memory Multi-Processor System. It can be used for applications that require only a few processors, yet large-scale data computation and analysis are needed. Its advantages include simple system architecture, easy management and easy to compile parallel computing programs. Disadvantages include poor system scalability and high expansion cost for high-end models which are similar to outdated mainframe systems. With the technical development of complex instruction set rocessors, GIGABYTE’s new R292 series servers can support 4 processors in one single node to effectively mitigate the disadvantage of poor scalability while providing customers with high flexibility.
Massively Parallel Processing (MPP)
This system consists of many computing nodes with independent local memories and a microkernel operating system. As the system usually has no global memory and is centrally managed by a main operating system combined with the micro kernels of all nodes, it is also called Distributed Memory Parallel (DMP). Its advantage includes high system scalability and disadvantages include allocation of user memories to different nodes and difficulty in creating parallel computing programs. To address the issues of computation failure in a node, such system architecture has evolved to provide high availability and node computation tasks. That’s why the High Performance Computing (HPC) Cluster was born.

The HPC Cluster usually uses a cluster of nodes with the same hardware and operating system to create a parallel computing system via a network connection. Its primary advantages include extremely high flexibility and cost-effectiveness of computing capacity expan-sion through standardized host technology. Disadvantages include well-designed software suites - more specifically, parallelization - needed for optimal performance.
Heterogeneous Computing
At the current stage, it’s preferred to combine CPUs with GPUs, FPGAs or ASIC kernel acceleration cards for heterogeneous computing. In recent years, the conventional way of computation by utilizing CPU frequency and kernel count has encountered a bottleneck in its ability to dissipate heat. Meanwhile, GPU, FPGA and ASIC cards have increasingly evolved to a higher kernel count and better parallel computing power. As such a system that boasts a high overall ratio of performance/chip area and a performance/watt, the accelerated computation of science, business analysis and engineering application can be improved to a large extent. By combining the servers optimized for sequential processing from GIGABYTE with different types of acceleration cards in collaboration with thousands of small computing cores, heterogeneous computing has obviously become one of the mainstream high performance computing systems today.
High Performance Computing System
Whether it’s MPP or a heterogeneous computing-based high performance computing system, its nodes consist of three application types.
Based on our long-term tracking of technical developments and observation of market trends, we at GIGABYTE have been working on the product planning and deployment of high performance computing systems from an early stage in order to offer customers more flexible options by launching a wide array of products for different architectures and cluster nodes, including:
