The SIMM framework is based on first-order greeks to make it more computationally tractable than other methodologies such as Expected Historical VaR. Maxeler’s SIMM calculation product powered by Xilinx Alveo U200 provides an industry-proven risk analytics infrastructure. SIMM product splits naturally into the calculation of sensitivities, and the application of risk weights and aggregation. The Maxeler Risk Analytics library provides the framework for calculating greeks on CPUs as well as on Xilinx U200 Acceleration card. Initial margin requirements can be calculated directly from a portfolio of trades supplied in FpML format, or indirectly by supplying sensitivity values from external models (for example, a liability exposure to be hedged).
