Abstract
A capsule is a liquid drop enclosed by a thin membrane. Understanding the mechanics of capsule suspension is important in a variety of applications. However, computational time is still a barrier against successful simulations for dense suspension of capsules. We have developedan ultra-highspeed computation method based on Graphics Processing Unit (GPU) computing for simulatin gmulti-capsule flow. In the case of using single GPU, the performance achieves 1. 20 TFlops that correspondsto a 550-foldspeed up comparedwith a CPU core. We also developed an algorithm of multi GPUs that hide data communication by overlapping with computational time. Since our method enables us to simulate from one to a few hundredcapsules in a realistic computationaltime, the methodcouldbe a powerful solution for simulating the capsule suspension.
