rinnakkaisella

Rinnakkaisella is the adessive singular form of the Finnish adjective rinnakkainen, meaning parallel or side-by-side. It is used to describe something that is done in parallel, located in a parallel manner, or used as a means to achieve parallelism. In everyday and technical Finnish, rinnakkaisella conveys how something is performed or organized from the perspective of manner or method.

In practice, rinnakkaisella appears in contexts such as computing, engineering, and project planning to express parallelism or concurrent operation. For example, in information technology one might say: Tietojenkäsittelyssä rinnakkaisella ohjelmoinnilla voidaan suorittaa useita laskutoimituksia samanaikaisesti, meaning that parallel programming enables multiple calculations to run at the same time. Another common usage is with phrases like rinnakkaisella lähestymistavalla or rinnakkaisella prosessoinnilla to indicate a parallel approach or processing.

Grammatically, rinnakkaisella functions as an adjective in the adessive case and agrees with the noun it modifies, indicating the manner or means. It contrasts with other forms such as rinnakkaisesta (genitive) or rinnakkainen (nominative).

Related terms include rinnakkaisuus, the noun expressing the state or quality of being parallel, and rinnakkaislaskenta or rinnakkaissekäyttö, which refer to parallel computation and parallel usage, respectively. These terms are commonly found in technical and scientific Finnish, where parallelism is a key concept.

In sum, rinnakkaisella marks parallelism in a descriptive or instrumental sense, used to specify that actions or components occur or are arranged in parallel.
