ALLINEA SOFTWARE LIMITED

Their core work

Allinea Software develops performance analysis, debugging, and profiling tools for high-performance computing (HPC) systems. In H2020 projects, they contributed specialist software expertise to help research teams measure, optimize, and scale scientific applications on supercomputers and emerging exascale architectures. Their tools help scientists understand why their code runs slowly and how to fix it — a critical bottleneck in computational research. The company was acquired by ARM Holdings in 2016, making their H2020 participation part of a transition period in the HPC tools market.

What they specialise in

How they've shifted over time

All five of Allinea's H2020 projects began in 2015, so there is no meaningful temporal shift in focus — their participation represents a single concentrated engagement period rather than an evolving trajectory. Their work consistently spans HPC performance tools applied to exascale hardware, storage, and scientific simulation workloads. The company was acquired by ARM in 2016, which likely explains why no further H2020 projects appeared after this initial batch.

Allinea's trajectory ended with its ARM acquisition in 2016; their HPC tools expertise now lives within ARM's HPC division (Arm Forge), so future collaborations would route through ARM rather than this entity.

How they like to work

Allinea consistently served as a specialist participant, never coordinating any of its five projects. With 48 unique partners across 12 countries, they operated as a focused contributor embedded in large European HPC consortia. Their role was to bring commercial-grade performance tools into research infrastructure projects — a clear "tool provider" pattern rather than a research driver.

Collaborated with 48 unique partners across 12 countries, reflecting deep integration into Europe's HPC research ecosystem. Their network spans major supercomputing centers, universities, and hardware vendors involved in exascale preparedness.

What sets them apart

Allinea occupied a rare niche as a commercial SME providing production-quality HPC debugging and profiling tools to the European research computing community. Unlike academic partners who build prototype tools, Allinea delivered commercially supported software that researchers could rely on for real workloads. This made them a valuable bridge between academic HPC projects and usable, deployable software — though this capability now sits within ARM's portfolio.

Highlights from their portfolio

• NEXTGenIO
  Largest funding share (EUR 178,846) and focused on next-generation exascale I/O with non-volatile memory — a hardware-software co-design challenge well-suited to performance tool expertise.
• ComPat
  Most technically descriptive project in the portfolio, addressing computing patterns for multiscale simulation with explicit performance measurement and prediction components.
• ESiWACE
  Applied HPC performance expertise to weather and climate simulation — a domain with massive societal impact and demanding computational requirements.
