+ | |||
+ | ==== History ==== | ||
+ | |||
+ | In 2006, 4 Wesleyan qfaculty members approached ITS with a proposal to centrally manage a whigh performance computing center (HPCC) seeding the effort with an NSF grant (about $190K). ITS offered 0.5 FTE for a dedicated " | ||
+ | |||
+ | The Advisory Group meets with the user base yearly in reading week of the Spring semester (early May) before everybody scatters for the summer. At this meeting the hpcadmin reviews the past year, previews the coming year and users are contributing feedback on progress and problems. | ||

+ | ==== Structure ==== | ||

+ | The Wesleyan HPCC is part of the **Scientific Computing and Informatics Center** ([[https:// | ||

+ | ==== Funding Policy ==== | ||
+ | |||
+ | After an 8 year run of the HPCC, and a drying up of grant opportunities at NSF, it was decided to explore self-funding so the HPCC effort could continue without external dependence on funds. A report was made of the HPCC progress including topics such as Publications, | ||
+ | |||
+ | Several months later a pattern emerged. | ||
+ | |||
+ | In order for the HPC user base to raise $15K annually, CPU and GPU hourly usage was deployed. A dictionary is maintained listing PIs and their members (students majors, lab students, grads, phd candidates, collaborators, | ||
