Results worth building on. Spectral computation is often one stage in a larger simulation or signal-processing workflow. SpectralForge provides large transform, convolution and supported spectral-PDE operations with checks designed to assess numerical consistency. It lets a team evaluate the actual computational stage—including its precision and memory requirements—rather than treat one transform timing as a complete application result. BUILT FOR Scientific-computing and signal-processing teams using supported spectral operations. CHALLENGES PRODUCT RESPONSE ## The problem you face. What SpectralForge changes. 01 ### Large transforms strain the compute budget A larger grid changes the memory and execution requirements of the spectral stage. SpectralForge supplies a large-scale transform path for the supported problem and execution environment. 02 ### Transform consistency needs checking A numerical array can have the correct shape while still containing an incorrect transform result. The product’s independent consistency checks assess the transform output under its documented numerical conventions. 03 ### The useful task is more than an FFT A customer may need a convolution or supported PDE computation, not a transform presented in isolation. SpectralForge’s stated scope includes those computational tasks, allowing the selected stage to be evaluated in the full workflow. WHAT YOU GET ## A defined capability. A useful output. The product scope below describes the capability and outputs to confirm for your release. Custom integration, operated delivery and additional engineering are separately agreed. 01 ### Large transform operations FFT capability for the supported sizes and configurations. 02 ### Convolution functionality The supported convolution path for the customer workload. 03 ### Spectral-PDE solves The admitted PDE computation scope rather than a general-purpose PDE platform. 04 ### Numerical consistency checks Independent checks and reference comparisons for the selected operation. AVAILABLE NOW ## One product. Three ways to work. SpectralForge is fully available with CLI, MCP and headless access. Use the interface that fits your terminal, your agents or your automated workflow. 01 / CLI ### For your terminal. Run the product from a terminal or script, alongside the tools your team already uses. [Get CLI access](https://spin-forge.com/contact?product=forge15%2Fspectralforge&interface=cli&brief=I+would+like+SpectralForge+access+through+CLI.+Please+share+the+setup+documentation+and+configuration+for+the+selected+product.+We+will+confirm+the+environment%2C+license+scope+and+workflow+during+onboarding.) 02 / MCP ### For your agents. Connect MCP-compatible clients and agents to the product’s exposed capabilities. [Get MCP access](https://spin-forge.com/contact?product=forge15%2Fspectralforge&interface=mcp&brief=I+would+like+SpectralForge+access+through+MCP.+Please+share+the+setup+documentation+and+configuration+for+the+selected+product.+We+will+confirm+the+environment%2C+license+scope+and+workflow+during+onboarding.) 03 / HEADLESS ### For your workflows. Operate without a graphical interface in unattended, scheduled or pipeline-driven work. [Set up headless access](https://spin-forge.com/contact?product=forge15%2Fspectralforge&interface=headless&brief=I+would+like+SpectralForge+access+through+headless.+Please+share+the+setup+documentation+and+configuration+for+the+selected+product.+We+will+confirm+the+environment%2C+license+scope+and+workflow+during+onboarding.) Product-specific inputs, hardware requirements and result guarantees still apply. An access mode does not change your license or deployment scope.

Illustrative use of the supported scope, not a customer case study or a measured result. 1. 01 Specify the grid, operation, precision and boundary conventions. 2. 02 Run the supported transform or PDE stage. 3. 03 Compare numerical consistency, reference error and complete-stage runtime. IN YOUR WORKFLOW ## Start with your task. Agree the useful outcome. Scientific-computing and signal-processing teams using supported spectral operations. What you bring The supported operation, array/grid dimensions, precision and relevant PDE or convolution conventions. What a useful evaluation measures - Numerical consistency and reference error - Memory at the requested grid size - Time for the selected computational stage Where it fits Use the selected product in a qualified customer environment, or agree a defined implementation with SpinForge. A hosted or managed service is quoted for its actual operating responsibilities; it is not automatically included with software access. QUESTIONS BEFORE YOU BUY ## A clear scope. No hidden assumptions. **How can we use SpectralForge?**CLI, MCP and headless access are all available. Run from a terminal or script, connect an MCP-compatible client, or use the product without a graphical interface. Choose the mode during onboarding and receive its setup instructions. Runtime requirements and supported operations remain product-specific. **What is the important product boundary? **The reported 256-million-point Poisson example is a particular closed-form comparison. Consistency checks are not proof that every scientific model is physically correct or that all PDE classes are supported. **What comes with the selected license? **The agreed SpectralForge release, its supported interfaces and outputs, the applicable checks and the support stated in your order. The plan defines users, workflow, environment and capacity. Source-code transfer, unrestricted redistribution and bespoke engineering are not automatically included. **Can SpinForge implement or operate it for us? **Request a scoped engineering or operated-service proposal. It identifies what our team delivers, where the workload runs, infrastructure costs, acceptance requirements and ongoing support. Your software subscription alone does not activate a hosted runtime. [Explore engineering](https://spin-forge.com/engineering) **What evidence is available for review? **P43 / Company-reported. A reported 256-million-point Poisson computation agreed with the closed-form answer at round-off error. This is a particular reference problem and numerical setting, not general PDE qualification. These descriptions come from the supplied product and campaign material. Website checks are not an independent rerun of the engine. Qualification identifies the actual release, workload and available artifacts.
