Takahiro Hirofuchi visited ACIS Lab of University Florida in February and March 2012. ACIS Lab and AIST started a joint research in 2011, which are partly funded by NSF and JST. We are studying advanced virtualization technologies for disaster-tolerant IT infrastructure. Takahiro loved Gainesville so much. It's a small university town and provides a good work-life balance environment. This visit was very productive.
