The TSYS School's chapter of ColorStack has been reactivated, thanks in large part to computer science senior Camron Jones. "I'm excited to share that the ColorStack at Columbus State University is officially reactivated. I'm honored to serve as the President of our chapter and help build a community that empowers and supports students pursuing careers in technology," Jones explained. ColorStack's mission is to increase the number of Black and Hispanic computer science students who graduate and launch rewarding careers in tech. "At CSU, we're committed to creating opportunities for students through professional development, technical workshops, networking events, recruiter connections, mentorship, and a strong community of peers. This milestone wouldn't have been possible without the support of our faculty advisor, University administration, and the students who believed in bringing this organization back to campus. Thank you to everyone who h...
TSYS School Computer Scientist Yi Zhou Publishes Research on Optimizing System Longevity and Performance
New research by TSYS School computer scientist Yi Zhou and his colleagues Hui Sun of Anhui University, Yajie Deng of Northwestern Polytechnical University, and Xiao Qin of Auburn University explains that persistent memory (PM) bridges the latency and cost gap between dynamic random access memory (DRAM) and solid-state drives (SSD). As these researchers add, within the DRAM–PM–SSD hierarchy, deploying key-value-separated key-value stores (KV-separated stores) is imperative for optimizing system longevity and performance. This architecture mitigates SSD write amplification and preserves PM endurance by minimizing writes. According to Zhou et al., existing KV-separated stores in the DRAM-SSD architecture, however, fail to fully exploit this three-tier hierarchy due to three issues. First, LSM-tree indexes incur high read amplification on PM. While learned indexes offer faster reads, they suffer from severe write-read asymmetry that can undermine overall efficiency in write-intensive work...
