Continuing from the previous article on NFS file systems, the current requirement is to be able to control the applications running in the cluster. For example, if we need to run parallel cross-node program A, we need to schedule and stop the running program B. This requires building a messaging system that can perform operational tasks based on message drivers.

目前正学习如何在树莓派4集群上结合gromacs+mpich的分子动力学模拟，所以需要搭建一款分布式存储系统，又由于树莓派性能的限制，搭建OpenEBS会比较浪费计算资源，最后就采用轻量级的NFS来完成文件系统的共享和存储。

The Rosetta@home project computationally generated and used in animal experiments an immune protein for SARS-COV-2 that could serve to protect animals from a lethal new coronavirus, which is still in the experimental phase and is being optimized.

Blender is an open source 3D modeling program, which I have been learning in order to use digital painting MattePainting techniques in creating short films, such as asset creation and 2.5D compositing in scene widening, and the corresponding commercial modeling programs are Maya, 3DCoat, 3dsMax, SideFx, Houdini. The advantage of Blender over commercial modeling programs is that first, it is an open source program, and second, the whole modeling system has a self-contained workflow, from…
