iEx.ec aims at providing distributed applications running on the blockchain a scalable, secure and easy access to the services, the data-sets and the computing resources they need. Usage of Big Data and High Performance Computing applications and the infrastructures to run them is a necessity for the design of innovative products and services. HPC is too complex and too expensive for innovative SMEs and individuals. iEx.ec provides on-demand, secure and scalable access to an unlimited set of computing resources (CPU, storage, GPU). Their technology is based on XtremWeb-HEP, a software for parallel and distributed computing used in production in the public domain for 10 years (signal processing, image, high energy physics, aeronautics, finance). iEx.ec relies on the Ethereum blockchain to organize a global P2P market, where everyone can rent computing resources and applications. This lowers the cost of IT and provides better energy efficiency.
