Riga Technical University accelerates genomic research with Gcore GPU Cloud
We saw a 95% reduction in processing time, but more than speed, we also gained flexibility. We could scale from 2 to 8 GPUs instantly, and because usage was on-demand, we only paid for what we needed.Andris Locāns, Head of RTU HPCCompany backgroundRiga Technical University High-Performance Computing Center (RTU HPC) is Latvia’s largest supercomputing resource provider, supporting scientific and technological advancements across the Baltic region. RTU HPC has collaborated with multiple research institutions, including the Latvian Biomedical Research and Study Centre (BMC), a leader in molecular biology and biomedical research. BMC’s genomic research focuses on analyzing thousands of human genomes as part of European initiatives.Accelerating AI-powered genomic processing without compromising controlGenomic research is essential for understanding human health and disease origins, but like any activity that requires sizeable data-set processing, its computational demands are immense. In Latvia, the Riga Technical University High Performance Computing Center (RTU HPC) is leading a shift from traditional scientific computing toward an AI-first model of innovation.Working alongside the Latvian Biomedical Research and Study Centre (BMC), the team set out to solve a critical challenge: rapidly process thousands of human genomes using AI, without losing time or control to hardware bottlenecks or foreign cloud vendors.Essentially, what we wanted was to accelerate variant calling, the computational process of identifying genetic variations.Edgars Liepa, Scientific Assistant, BMCTraditional CPU-based computing often struggles with large-scale genome sequencing and analysis, leading to extended processing times. As a result, the RTU HPC faced several key challenges:The need for faster genome sequencing to support biomedical research.High compute requirements for analyzing large datasets efficiently.The difficulty of sourcing high-performance GPU hardware within a short timeframe.Ensuring cost-effective and scalable computing solutions without major upfront investments.GPU-as-a-service (GPUaaS) for genomic researchRTU HPC turned to Gcore, provisioning Cloud GPUs for immediate access to high-performance computing. Instead of waiting months for on-premises GPU hardware, they gained on-demand access to NVIDIA’s most advanced GPUs—including the H100, designed for AI inference at scale, and located on Gcore’s European cloud infrastructure.“We didn’t want to offload sensitive health data to platforms outside our legal jurisdiction,” Andris Locāns, Head of RTU HPC explains. “Gcore extensive infrastructure enabled us to maintain data sovereignty and compliance by keeping our data in-region, while still delivering the AI acceleration we needed.”This immediately unlocked the following benefits for the team:Instant access to powerful GPUs: Avoiding long procurement cycles for physical infrastructure.Scalability & cost-efficiency: Gcore’s pay-as-you-go model allowed RTU HPC to allocate resources flexibly based on research demands.Data sovereignty: Ensuring genomic data remains within a secure, compliant cloud infrastructure in the Baltic region.Optimized performance: Benchmarking multiple GPU configurations (V100, A100, L40S, H100) for genomic analysis with NVIDIA Clara Parabricks software.“With Gcore, we had near-instant access to compute that would have taken us six months to deploy internally,” says Edgars Liepa, Scientific Assistant at BMC. “That completely changed the pace of our work.”Benchmarking performance for maximum efficiencyRTU HPC and BMC collaborated with Gcore to conduct extensive performance tests on various GPU configurations. By leveraging Cloud GPUs, they identified optimal setups for accelerating genomic workflows.Comparison of CPU vs. GPU: Genome sequencing that previously took over 650 minutes on CPUs was reduced to under 30 minutes with GPU-powered processing.Testing NVIDIA GPUs: Experiments with GPU configurations provided insights into computational efficiency, with findings indicating that scaling up GPUs did not always equate to faster processing.Future discussions with NVIDIA: Gcore’s collaboration enabled further optimizations in GPU usage for genomic analysis.A comparison of CPU and GPU computing times: while CPU processing time exceeded 650 minutes, it could be significantly reduced to under 30 minutes for all tested configurations when using fq2bam H100Faster, scalable, and cost-effective genomic researchNVIDIA H100 GPUs, provided as-a-service by Gcore, delivered graphics processing units with a compute performance that is revolutionizing cloud infrastructure. They are also specifically designed with the power required for high-performance computing tasks such as computational genomics. “It was important for us to see how fast inference runs on the H100,” says Edgars Liepa, “We didn’t customize the model but instead used one developed by NVIDIA, which was already well suited for our task.”The collaboration between RTU HPC, BMC, and Gcore delivered significant benefits to the research program, including:Significant reduction in processing time: Variant calling tasks were completed up to 50x faster.Cost savings with on-demand GPUs: Eliminating upfront hardware investments while optimizing computing costs.Scalable infrastructure: The ability to dynamically allocate resources based on real-time needs.Data sovereignty and security: Genomic data was processed within a compliant, secure cloud environment.The measured processing times of the tested H100 GPUs in detail: the processing time ranged from 13 minutes for haplotypecaller H100 with 2 GPUs used to just under 90 minutes for Deepvariant H100 with 8 GPUs used, indicating that GPU overhead can slow down the processing time when the effective memory limit is reached“It’s not just about going faster,” Liepa adds. “It’s about enabling analysis at a national scale. The AI models are there—but without the right compute power, they’re just theory.”Advancing high-performance genomics in the Baltics and beyondBy leveraging Gcore’s Cloud GPUs, RTU HPC has established a model for scalable, cost-effective genomic research, and this is only the beginning. Now that the speed and flexibility has been proven on genomics processing, RTU HPC plan to broaden AI applications even further.Wider adoption of Cloud GPUs in genomics: RTU HPC is considering Cloud GPUs expansion for broader research applications.Future collaboration with Gcore: Optimization of GPU configurations will continue, and RTU HPC plans to explore AI Inference opportunities with Gcore Everywhere Inference for genomic workloads.Global implications: BMC’s work with the 1+ Million Genomes Project, an EU-wide initiative to make genomic information more accessible for diagnosis and treatment, contributes to international research efforts.The benchmark test results for H100 GPUs using 2, 4, or 8 GPUs: fq2bam and haplotypecaller achieved the shortest processing times on average and comparatively consistent results across 2, 4, and 8 GPUsPioneering AI-powered genomics with sovereign cloud infrastructure“This is the future of AI in healthcare: fast, flexible, sovereign,” says Liepa. “Gcore gave us the infrastructure to make it real—not just for today, but for what comes next.”As AI continues to transform life sciences, the ability to combine cutting-edge GPU performance, regional data compliance, and on-demand scalability is emerging as the key to competitive advantage—not just for companies, but for countries.“We’re proud to support Latvia’s vision for AI-powered genomics,” says Vsevolod Vayner, Product Director of Edge & AI Cloud at Gcore. “This project is a blueprint for how nations can lead in biotech innovation without giving up digital sovereignty.”Find out more about how Gcore Cloud GPUs can enhance your high-performance computing projects.Try Gcore Cloud GPUs
LetzAI rapidly scales AI-powered image generation for global users
Everywhere Inference reduces the latency of our output and enhances the performance of AI-enabled apps, allowing us to optimize our workflows for more accurate, real-time results.Misch Strotz, CEO and co-founder, LetzAIA futuristic tram journey, blending reality and imagination, created with LetzAI. Destination: To the MoonLaunched as a skunkworks project from within Neon Internet, LetzAI is quickly becoming a go-to platform for high-quality AI-generated images. With a mission to democratize and personalize AI-powered image generation, it has emerged as one of the most popular and high-quality options on the market. To support its rapid growth and scale seamlessly, LetzAI partnered with Gcore for advanced AI and cloud infrastructure.Global GPU shortages threaten to derail a new AI image generation ideaIn 2023, Neon Internet CEO and co-founder Misch Strotz was struck by a clever idea: give Luxembourg residents the power to easily generate local images using AI. Within a month, Luxembourg-focused LetzAI V1 went live.Encouraged by strong local demand, Strotz and his team began working on a global version of the platform. The vision? An opt-in AI platform empowering brands, creators, artists, and individuals to unlock endless creative possibilities by adding their own images, art styles, and products. “Other AI platforms scrape the internet, incorporating people and their content without permission. We wanted to put the choice and power in each person’s hands,” Strotz explains.Before long, the team began working on V2. In addition to generating higher quality and more personalized AI-generated images, V2 would drive consistency across objects, characters, and styles. After uploading their own photos and creating their own models, users can blend them with other models created by the community to create an endless number of unique images.However, LetzAI faced a significant hurdle in training and launching V2—a global GPU shortage. With limited resources to train its models, LetzAI needed a reliable partner to help evolve its AI-driven platform and keep it operating smoothly.Finding a trusted, Europe-based AI partnerIn the search for a fitting partner, Strotz spoke to major vendors including hyperscalers and various Europe-based providers. Meeting Gcore’s product leadership team made the decision clear. “It was amazing to meet executives who were so knowledgeable about technology and took us seriously,” recalls Strotz.Gcore’s approach to data security and sovereignty further solidified the decision. “We needed a trusted partner who shared our commitment to European data protection principles, which we incorporated into the development of our platform” he continues.Maximizing AI efficiency by training on local GPUsLetzAI opted for Gcore’s state-of-the-art NVIDIA H100 GPUs in Luxembourg. “This was the perfect option, allowing us to keep our model training and development local. With Gcore, we can rent GPUs rather than entire servers, making it a far more cost-effective solution by avoiding unnecessary costs like excess storage and idle server capacity,” Strotz explains. This approach provided flexibility, efficiency, and high performance, tailored specifically for AI workloads.LetzAI was able to adapt its app to run in containers, configure model training tasks to run on GPU Cloud, and use Everywhere Inference for image generation and upscaling. “Everywhere Inference reduces the latency of our output and enhances the performance of AI-enabled apps, allowing us to optimize our workflows for more accurate, real-time results,” Strotz says.In just two months, LetzAI V2 launched to serve users around the world. And Strotz and team were already developing its successor.Empowering creativity with scalable, high-performance AI infrastructureWith Gcore’s continued support, LetzAI quickly deployed V3. “The Gcore team was incredibly responsive to our needs, guiding us to the best solution for our evolving requirements. This has given us a powerful and efficient infrastructure that can flex according to demand,” says Strotz.Running V3 on Gcore means LetzAI users experience fast, reliable performance. Artists, individuals, and brands are already putting V3 to use in interesting ways. For example, in response to what LetzAI calls its ‘AI Challenges’, a Luxembourg restaurant chain prompted residents to create thousands of images using its model of a pizza.In another example, LetzAI teamed with digital agency LOOP to dress PUMA’s virtual influencer and avatar, Laila, in a Moroccan soccer jersey. According to Strotz, “PUMA had struggled to make clothing look realistic on Laila. When they saw our images, they said the result was 1,000 times better than anything they had tried.”That wasn’t the only brand intrigued by V3’s possibilities. After LetzAI posted V3-generated images of models wearing Sloggi underwear, Sloggi’s creative agency STAN Studios asked LetzAI to generate more images for market testing.Always looking for new ways to support creators, LetzAI also launched its Image Upscaler feature, which enhances images and doubles their resolution. “Our creators can now resolve common AI image issues around quality and resolution. Everywhere Inference is pivotal in delivering the power and speed needed for these dynamic image enhancements,” notes Strotz.Platform evolution and AI innovation without limitsAs its models exceed user expectations worldwide, LetzAI can rely on Gcore to handle a high volume of requests. Confident about generating a limitless number of high-quality images on the fly, LetzAI can continue to scale rapidly to become a sustainable, innovation-driven business.“As we further evolve—such as by adding video features to our platform—our partnership with Gcore will be central to LetzAI’s continued success,” Strotz concludes.
