Genomics and Bioinformatics HPC

Genomics and bioinformatics research has undergone a dramatic transformation over the last decade, both in data volume and analytical depth. A single whole genome sequencing (WGS) study generates hundreds of gigabytes of raw data, while large cohort studies reach petabyte scale. Converting this data into biological meaning — alignment, variant calling, functional annotation, and statistical analysis — requires a computing capacity far beyond standard server hardware.

Why Is HPC Essential in Genomics Research?

If a clinical research laboratory is processing dozens of WGS samples daily, the GATK Best Practices pipeline for each sample takes 48–72 hours on CPU-based infrastructure. Twenty samples running in parallel create a backlog as their processing times stack up; scientific results are delayed and experimental flow is disrupted.

HPC clusters solve this problem through two channels:

1. Horizontal scaling: Each sample is distributed to different nodes for parallel processing; as the cohort grows, cluster capacity can be expanded.
2. GPU acceleration: GPU-accelerated tools like NVIDIA Parabricks accelerate the GATK pipeline by 50×, reducing per-sample processing time to 1–2 hours.

Across a wide spectrum — from academia to clinical diagnostic labs, agricultural genetics companies to biotech startups — HPC is the core infrastructure for competitive research speed.

Core Workload Categories

1. Whole Genome and Exome Sequencing (WGS / WES)

The WGS pipeline consists of alignment, duplicate marking, variant calling, and filtering stages. Each stage has a different compute profile:

High I/O requirement: During alignment and sorting stages, dozens of GB of temporary files are generated per sample. Even single nodes with NVMe hit I/O bottlenecks without a parallel file system (BeeGFS or Lustre).

2. RNA-seq and Transcriptomic Analyses

The standard workflow for RNA sequencing, gene expression measurement, and alternative splicing research includes these tools:

scRNA-seq workloads are memory-intensive: a dataset of 500,000 cells in Seurat may require 256–512 GB RAM.

3. Protein Structure Prediction and Structural Bioinformatics

With the public release of AlphaFold 2 and AlphaFold 3, structural bioinformatics research has gained new momentum.

4. Variant Annotation and Large Cohort Analyses

Software Ecosystem: Requirements per Tool

Data Security and KVKK Compliance

Genomic data constitutes the most sensitive subset of personal data. An individual’s complete genome can identify not just themselves but their first-degree relatives as well. This places genomics research under the special category personal data processing regime within KVKK scope.

Critical KVKK requirements:

Mevasis infrastructure is located in data centers in Turkey. Genomics research institutions can directly satisfy KVKK requirements without additional legal arrangements with cloud providers.

For WGS analysis, should I choose Parabricks or CPU-based GATK? Parabricks is the clearly recommended option for laboratories processing 5 or more samples daily. With H100 GPU, the 30× WGS pipeline completes in ~45 minutes, while the same job takes 48–72 hours on a CPU cluster. When initial hardware costs are factored in, the GPU investment amortizes quickly as annual throughput increases.

What is the minimum GPU requirement for AlphaFold installation? A100 80 GB is recommended for AlphaFold 2; the 40 GB memory limit can cause issues with large proteins. H100 80 GB or H100 NVL 94 GB is more suitable for large multimer complexes. AlphaFold 3 officially requires A100 80 GB.

How much RAM is sufficient for scRNA-seq analyses? Standard datasets with 10,000–50,000 cells require 128–256 GB RAM. Large atlas projects with 200,000+ cells may require 512 GB–1 TB RAM. GPU-based analysis with Rapids cuML both increases speed and reduces RAM requirements for large datasets.

What is the advantage of keeping genomic data on-premise versus cloud? There are three primary advantages: speed, cost predictability, and KVKK compliance. For large cohort studies, petabyte-scale data transfer is disadvantageous for cloud use in both time and cost. Under KVKK, processing special category health/genomic data outside Turkey’s borders carries legal risk.

What is the difference between BeeGFS and NFS, and which is necessary for genomics? NFS is adequate for serial workloads, but creates bottlenecks under high I/O loads like parallel alignment (BWA-MEM2) or simultaneous multiple Parabricks jobs. BeeGFS or Lustre provides 5–20× higher total bandwidth under this load and is strongly recommended for genomics HPC.
