![]() AWS cloud does provide some educational free cloud processing but when these free credits are over you would need to pay for processing and storage, and this can very quickly get expensive. Similar ‘containers’ can be accessed using AWS cloud services or through academic services such as CLIMB. Because we are having to reserve a proportion of the server for each user we can only allocate a limited number of processors and RAM to each user - usually this is 8 processors and 16 Gb RAM, but check with your course organiser. Each user has dedicated processors, RAM, storage and their own environment so they can interactively learn to use a Linux system. To do this we create a container which has the equivalent of a ‘virtual machine’ (VM) in the cloud we use a system called Kubernetes to create these container-based virtual machines. To avoid the queues we provide personal cloud systems to each person on the course, allowing them to interactively use the HPC system. This can be very tedious when learning to code, as if your script creates an error you won’t know until it has waited its turn in the queue. without sending them to the queue, most tasks need to go through the queue. Although you can do the very lightest tasks - copy small files, rename etc. In this way the system can support large numbers of users, but you need to wait for your place in the queue before your task can be performed. To run your informatic tasks, you write a script that sends your job to a ‘queuing’ program which coordinates the processing requests of all the users on the system. Usually users are provided with a login to a shared HPC system with strictly controlled access and defined quotas. ![]() High performance computing (HPC) systems are large, multi-processor, large RAM ‘computers’ that are installed in data centres.
