AsiaBSDCon 2010 paper session.
Since 2001 we have used FreeBSD as a high performance computing (HPC) cluster operating system. In the process we have ported a number of HPC tools including Ganglia, Globus, Open MPI, and Sun Grid Engine. In this talk we will discuss the process of porting these types of applications and issues encountered while maintaining these tools. In addition to generally issues of porting code from one Unix-like operating system to another, there are several type of porting common to many HPC infrastructure codes which we will explore. Beyond porting, we will discuss how the ports collection aids our use of HPC applications and ways we think overall integration could be improved.
