MassGrid is a decentralized high-performance computing network. With the development of industries such as AI and VR, the demand for high-performance computing has also penetrated into various industries, and every company and team may not have the financial resources, capabilities and necessity to build a computing power cluster, even if it builds its own GPU computing. The maintenance and upgrade also require a lot of manpower, material resources and time costs. MassGrid can gather idle computing power scattered around the world to build a dynamically upgradeable GPU general-purpose computing power cluster, which can be used by all individuals or business organizations that need these computing power, effectively meeting their actual needs.
