Leading Innovations in High-Performance GPU Computing

Stream HPC is a leading and independent GPU and performance engineering company with 40+ specialists based in Europe, working with customers worldwide, including a strong customer base in North America.

For more than 15 years, we’ve specialized in high-performance C++, GPU computing, parallel algorithms and performance optimization. We have helped engineering and R&D teams accelerate compute-intensive software and turn difficult GPU performance problems into production software.

Our customers often come to us after trying to accelerate their software themselves and finding that the expected performance remains out of reach. We identify what’s holding the software back, test alternative approaches and engineer the solution.

Our specialists work at the intersection of software, algorithms and hardware, tackling performance problems where standard approaches are not enough.

What we specialize in

We specialize in the difficult part of performance engineering: understanding why software isn’t fast enough, determining what is realistically achievable, and engineering the solution.

Our expertise covers CUDA, HIP, SYCL, OpenCL, Vulkan and other parallel programming technologies, across NVIDIA, AMD, Intel and other computing architectures.

From a focused performance assessment to a full production implementation, we work alongside engineering teams to turn performance challenges into working software.

“We did not expect you would exist, when searching for GPU-engineering companies”

You have a compute-intensive application that needs to be faster. Perhaps you’ve already tried GPU acceleration, profiling or parallelization and haven’t achieved the performance you expected. Stream HPC helps identify what’s holding the software back, evaluate alternative approaches and turn the most promising solution into production software.

We work for:

• Engineering companies
• Semiconductor companies
• Robotics companies
• Industrial R&D
• Technology companies
• Companies with difficult compute problems
• Scientific organizations
