A new speed record has been obtained with EMPIRE XCcel. On the Intel Core i7-2600 (3.4GHz, 8MB L3, 1666 MHZ, Single Quad Core) a simulation performance of up to 2120 MCells/s could be achieved using the upcoming version 5.50.
This processor features the Advanced Vector Extensions (AVX) which is able to treat 8 single precision floating point operations in one cycle. With its on-the-fly structure and processor adapted code generation EMPIRE XCcel fully exploits this processor feature while using the last level cache (LLC) for multiple time stepping and parallelization on all built-in cores (XPU technology).
In contrast to solutions which make use of graphic card accelerators (GPU) the performance obtained with EMPIRE XCcel allows the usage of the complete built-in memory. On a 64 bit operation system up to 192 GByte can be used today with the full simulation performance.
