Abstract: We investigated the asymmetry in the structure of complex software. After studying the degree distribution of the call graphs corresponding to the Linux kernel modules of 223 different versions, we found the asymmetry between the in-degree and out-degree distributions. After analyzing the behaviors of the newly added nodes in each version, we found that the preferential attachment behaviors of the new nodes are not only related with the degree of nodes, also related with the "age" of nodes, especially in the out-degree. In addition, the new nodes tend to cluster in Linux kernel.
