IMST invented a proprietary software acceleration technique for FDTD simulation on modern CPU‘s.

Numerical techniques:

• Specific C- & assembler-code created for each simulation to fit CPU architecture and simulation model
• Individual code adaptation for latest CPU’s (AVX, AVX2, AVX 512, …)
• Efficient caching & compression of FDTD coefficients
• Speed not limited by RAM access time due to efficient last level cache usage (multiple time step principle)
• The XPU technique calculates the updates for the E- and H-fields combining multiple time steps of the fields calculated in the cache memory of every core of the CPU
• IMST invented software acceleration technique for FDTD simulation
  on modern CPU‘s

Key Advantages:

• Ability to access the complete RAM of PC (> 2 TB today)
• High simulation speed for all simulation model sizes
• Reduced memory usage compared to standard FDTD
• Multiple PC’s using the XPU technique can be efficiently clustered using a similar multi time step principle applied between different PC’s
• Support of cloud computing on Amazon EC2 and Microsoft Azure cluster
