English: Overview of access options for iPlant's major cyberinfrastructure components. iPlant's CI consists of several major systems, each of which provides a set of computational resources for different types of users. The basic level of services provides access to data and data analysis algorithms. For large datasets, there are two general paradigms for computing: high-throughput computing (HTC) and high-performance computing (HPC). The major difference is that HTC provides rapid access to many different data types requiring discreet computation while HPC provides access to many interlinked compute nodes for tightly coupled parallel computation. Data resides in iPlant's Data Store, a cloud-based distributed system for storing and sharing large quantities of data that are automatically replicated between iPlant's major sites. iPlant resources can be accessed directly or through APIs. iPlant's Discovery Environment is a web-based system and provides functionality to manage data, add new algorithms and tools, and run analyses on appropriate computational resources. Atmosphere is iPlant's on-demand cloud computing resource that allows users to launch virtual machines, install complex software of their choice, connect to iPlant's Data Store and other compute resources, and share cloud resources with collaborators. Together, iPlant's CI proves a wealth of interconnected computational and data management resources to users with different needs and diverse levels of computational expertise.
