The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multilevel feedback scheduling. In addition, you will provide user programs with semaphores, a means to check the system s current time and a mechanism for passing command-line arguments

这个软件包(C++)是我寻找电磁学代码无意中找到了，功能相当强大（并行计算，快速多极子等）。缺点是安装相当麻烦，需要若干个其他软件包。我在Fedora Core9下编译其中所需blitz++时出错，在 ubuntu下可以所有均编译通过，运行时出现一个错误，我找不到原因（本人水平有限），但从学习电磁学有关算法／程序设计来说，已经是相当了不起的开源软件了。parallel unified multipole algorithm for Electromagnetics (Puma-EM). Aim is providing surface Method of Moments for Electromagnetics, enhanced by using the multilevel Fast Multipole Method. Code is parallelized and runs on Desktops and clusters.

Abstract—In the future communication applications, users may obtain their messages that have different importance levels distributively from several available sources, such as distributed storage or even devices belonging to other users. This scenario is the best modeled by the multilevel diversity coding systems (MDCS). To achieve perfect (information-theoretic) secrecy against wiretap channels, this paper investigates the fundamental limits on the secure rate region of the asymmetric MDCS (AMDCS), which include the symmetric case as a special case. Threshold perfect secrecy is added to the AMDCS model. The eavesdropper may have access to any one but not more than one subset of the channels but know nothing about the sources, as long as the size of the subset is not above the security level. The question of whether superposition (source separation) coding is optimal for such an AMDCS with threshold perfect secrecy is answered. A class of secure AMDCS (S-AMDCS) with an arbitrary number of encoders is solved, and it is shown that linear codes are optimal for this class of instances. However, in contrast with the secure symmetric MDCS, superposition is shown to be not optimal for S-AMDCS in general. In addition, necessary conditions on the existence of a secrecy key are determined as a design guideline.
