SparseSolver

I have an unhealthy obsession with sparse linear solvers. If they are on your critical path, I can probably make the problem go away.

In order of escalating cost

• Generic solver library (librankbreaker) org licenses
• librankbreaker support add-ons
• Consulting engagements

Please contact me to inquire on anything below or something more custom.

librankbreaker

A sparse linear solver library designed to do exceptionally well on nonsymmetric and indefinite systems, with low memory footprint.

Org licenses (internal use, non-redistributable)

• Solo: $1,000/yr — 1 engineer, ≤10 nodes
• Starter: $3,000/yr — ≤5 engineers, ≤50 nodes
• Pro: $9,000/yr — ≤25 engineers, ≤250 nodes
• Enterprise: custom — unlimited engineers & infra

30-day evaluation keys available. Annual renewals include new features and performance improvements.

Internal apps and services are fine. Redistribution/OEM or exposing the solver to third parties requires an OEM add-on.

librankbreaker support (optional add-ons)

• Baseline: $0 — bug-fix releases, best-effort email. No hours.
• Standard: +$3,000/yr — 24h/year, 2-business-day SLA.
• Priority: +$12,000/yr — 60h/year, 24–48h SLA.

Consulting

No interest in librankbreaker or need more bespoke help? I have experience with the following and am open to custom arrangements

• Large HPC systems and supercomputers
• Distributed solver technology e.g. MPI
• GPU technology: ROCM,CUDA,HIP
• Direct experience on wide variety of CPU architectures: graviton/ARM,intel,amd
