 Now that you know more about digital sizes, you can appreciate that this server can allow for much faster processing and really large amounts of storage, as again a researchers' computer might have something like 16 GB of RAM and 1TB of storage. 
 
-Currently, there are 68 nodes that make up the JHPCE currently. As with most clusters, some of the nodes are dedicated to managing user access to the cluster, and some of the nodes are dedicated to transferring data. Each node has 2-4 CPUs that provide 24-128 cores! As you can see, these processors or chips have a lot more cores per each CPU than a typical personal computer. 
+At the time of writing, JHPCE had 68 nodes. As with most clusters, some of the nodes are dedicated to managing user access to the cluster and some of the nodes are dedicated to transferring data.

 Individual users connect and perform jobs (a.k.a. computational tasks) on the cluster using a formal [common pool resource (CPR)](https://en.wikipedia.org/wiki/Common-pool_resource) hierarchy system. What does this mean? Recall that we are talking about shared resources, where if one user overused the resource, it may be to the detriment of other users' experiences. The CPR hierarchy system is comprised of rules and regulations designed to prevent this from happening, that are enforced by managers of the resource @common-pool_2022. This is important because if a single or a few users used up all the computing resources one day, then the other nearly 400 users would not be able to perform their work that day, which would not be fair.
