反正我不这么认为T4T网站上说他用了许多软件包,依赖很复杂。而且如果这些软件崩掉了也不会影响实际计算机里面的数据(重建个虚拟机就好了……)。
This project runs very large CERN software packages with complex dependencies that cannot be easily ported to all the volunteers' operating systems (Windows, GNU/Linux and Mac OS X). For this reason, we use a virtualization solution, which enables us to run complex codes independently of your platform. Additionally, using virtualization adds an extra layer of security, as if something goes wrong in the code execution this will not affect your computer.

Climate貌似我看到了用Fortran的编译器在编译源码……难道他用的软件是Fortran写得然后懒得编译出来(……)?
关于JAVA和C的效率差距@fwjmath 乃清楚么,我记得听@ManHo 说过完全虚拟化的性能损失大概是20%
