rinnakkaisissa

Rinnakkaisissa is a Finnish word form used in technical and scientific language to describe things that are arranged or occurring in parallel. It is the inessive plural form of the adjective rinnakkainen, meaning parallel or side-by-side, and it is typically attached to a plural noun to indicate parallelism in space or in processes.

The primary function of rinnakkaisissa is to modify a noun in the inessive plural, for example in phrases like rinnakkaisissa järjestelmissä (in parallel systems) or rinnakkaisissa prosesseissa (in parallel processes). In this use, it conveys that multiple elements operate or exist simultaneously or in a coordinated, parallel manner. The form is common in engineering, computing, physics, and systems design, where parallelism is a key concept.

Notes on usage: rinnakkaisissa is generally used with concrete plural nouns and describes arrangement or execution that is parallel rather than merely concurrent in time. For describing temporally simultaneous activity, the adverb rinnakkaisesti is often preferred. In Finnish, rinnakkaisuutta or rinnakkaisuus refer to the broader concept of parallelism, and rinnakkaisissa is the phrase used to situate that parallelism within a specific plural context.

Examples:

- Koodin osat voidaan suorittaa rinnakkaisissa prosesseissa.

- Sovellus tukee rinnakkaisissa järjestelmissä tapahtuvaa laskentaa.
