The term appears to be a misspelling or variation of OpenMP, an established API for shared-memory parallel programming. This article therefore provides an overview of OpenMP.
OpenMP is a portable API that enables multi-threaded parallelism in C, C++, and Fortran programs running on
Key features include work-sharing constructs (parallel, for, sections), synchronization primitives (barrier, critical, atomic), data scoping clauses
OpenMP is implemented by many compilers on major platforms and can be enabled at compile time with
