allinea

Allinea was a software company that developed debugging and performance analysis tools for high-performance computing (HPC). The firm focused on tools designed to assist developers in building, debugging, and optimizing parallel applications that run on clusters and supercomputers. Its products were widely used in scientific computing, engineering, and other fields that rely on large-scale parallel workloads.

The Allinea product family centered on three main tools. Allinea DDT was a parallel debugger used to diagnose bugs in MPI and multi-threaded applications, featuring capabilities for debugging across distributed processes and threads. Allinea MAP was a memory profiling tool that helped identify memory-related performance issues, such as cache misses and memory access patterns, across HPC codes. Allinea Forge was a performance analysis and optimization environment that provided insights into code behavior, hotspots, and scalability to guide performance improvements on parallel systems.

In 2013, ARM Holdings acquired Allinea. Following the acquisition, the Allinea tools were incorporated into ARM’s developer tools portfolio and rebranded under the ARM Forge and ARM DDT names. The Allinea brand gradually faded as the products continued to be marketed and supported as part of ARM’s HPC tooling line. Through this transition, the functionality and user base of the original Allinea tools persisted, continuing to support debugging, profiling, and optimization of large-scale parallel applications within the ARM ecosystem.
