The main goals of this undergraduate research mentoring program are i) to provide opportunities exploring diverse research topics in computer architecture, firmware, middleware and operating system, ii) to guide how to perform insightful research, iii) to teach them how to use diverse academic research tools such as Gem5, GPGPUsim and NANDFlashSim, and iv) to provide a chance connecting with graduate students to get more practice in performing research. As one of mentoring programming examples, Prof. Jung and his students have a series of research cleaning seminar for about 4 hours per week. Registered undergrad students explore GPU, SSD, multicore, NUMA, NUCA and emerging memory system research topics demonstrated at the top-tire conferences in computer architecture (e.g, ISCA, ASPLOS, MICRO, HPCA), and will perform computer architecture research with Prof. Jung's help.
