Colloq: Abstract: 
The Texas Advanced Computing Center (TACC) provides a large fraction of the computational resources of XSEDE, serving the scientific community throughout the country, and also offers systems for various research institutions in Texas. The number of users, codes and use cases, as well as the diverse backgrounds of the user community, create a wide variety of challenges for TACC researchers. In this presentation, I will discuss my research on some of the most representative challenges that the High Performance Computing group at TACC confronts when operating our HPC systems. I will identify the cause of the issues, as well as present some of the solutions that have been implemented and have successfully contributed to an enhanced utilization of our systems.
