Training – High Performance Computing (HPC) involves the utilization of the most powerful computer systems to advance the frontiers of science and engineering. Many, perhaps most, HPC users have or are pursuing formal education in a scientific or engineering discipline and are (or will become) self-taught programmers. Their aim is to provide training for a continuum of high performance computing environments that span desktop computing capabilities to the highest-end of computing facilities offered by HPC centers. All the courses incorporate both lectures and extensive hands-on sessions. Programming exercises are carefully designed to reinforce concepts and techniques taught in class. Their Instructors have strong technical backgrounds and are available for individual consultation, including help with participants’ own coding needs.

Rent-Our-Cluster – This service is for potential new HPC customers who want to try their new applications/ benchmark their applications on our in-house Infrastructure.

The motivation for this service is to enable access to compute-intensive jobs to the compute power they need (limited to available capacities on our cluster) over short period of time. This is designed for Engineers and Scientists who need processing power or results soon.  

  • Support – Customers have options of both basic mail and extended support. Extended support warranties a response time for resolution of issues.
  • First level – Helps users to solve basic issues such as: starting an account, checking requirements on the client side, providing users with instructions to run applications, answering questions regarding accounting and billing, etc….
