Questions and Answers

What is the main focus of HPC (High Performance Computing)?

  • Delivering high computational performance for scientific/engineering applications (correct)
  • Reducing power consumption and energy
  • Providing on-demand access to a shared pool of computing resources
  • Managing cloud computing infrastructure

How is HPC infrastructure typically owned and managed?

  • It is owned and managed by third-party cloud service providers
  • Organizations own and manage their dedicated HPC infrastructure (correct)
  • It is owned by individual users
  • It is managed by the government

What is the main difference between HPC and Cloud Computing?

  • Cloud Computing focuses on high computational performance for specific tasks, while HPC provides on-demand access to a shared pool of computing resources for general purposes
  • HPC and Cloud Computing are both used exclusively for scientific/engineering applications
  • HPC and Cloud Computing have no significant differences
  • HPC focuses on high computational performance for specific tasks, while Cloud Computing provides on-demand access to a shared pool of computing resources for general purposes (correct)
