Security in high-performance computing environments

High-performance computing ((HPC) systems have some similarities and some differences with traditional IT computing systems, which present both challenges and opportunities. One challenge is that HPC systems are 'high-performance' by definition, and so many traditional security techniques are not effective because they cannot keep up with the system or reduce performance. HPC systems tend to be used for very distinctive purposes, have much more regular and predictable activity, and contain highly custom hardware/software stacks. Each of these elements can provide a toehold for leveraging some aspect of the HPC platform to improve security
