Bio
John Cardente
During the summer of 2008 Songxiang Gu completed an internship with the Celerra Division of EMC Corporation. Specifically, Songxiang interned with the NAS Advanced Development group, a high performance engineering team chartered with developing new technologies and innovations for EMC's network storage product line. Throughout the internship I acted as Songxiang's manager responsible for defining his internship project, assigning tasks, and monitoring progress. For his internship Songxiang was given the task of creating a suite of software utilities for analyzing network traces of distributed file system protocols, specifically NFS and CIFS. Completing this project required Songxiang to quickly become familiar with both protocols, determine their semantic similarities and differences, and develop a method for representing both protocols in a common structured XML format. Songxiang then developed software utilities for converting protocol specific NFS and CIFS traces into the common format he defined. In addition, Songxiang wrote a variety of software utilities to analyze common format files including file system simulators, activity profilers, and statistical visualization tools. In total, Songxiang implemented 15K lines of C++ source code which, when compiled, produced a suite of Linux user-space command-line applications. Songxiang provided ample documentation for his software and utilized a consistent testing methodology to ensure its quality. During this work, Songxiang demonstrated significant engineering and software development skills. Throughout the internship Songxiang acted with a degree of professionalism far beyond that expected of an intern. He was organized, highly productive, and proactively provided weekly reports detailing his progress and plans for the following week. On a personal level Songxiang presented a friendly manner and interacted frequently with other group members in various social settings. By the end of his internship Songxiang was a fully integrated member of the team and a welcome presence. In summary, Songxiang successfully completed his internship despite many challenging assignments. He was professional, productive, and pleasurable to work with. He demonstrated a significant level of skill and an ability to quickly learn complicated topics. In summary, Songxiang is an excellent software engineer with valuable skills that I would not hesitate to hire again for the same or similar position.
