 **Hellbender** is the latest High Performance Computing (HPC) resource available to researchers and students (with sponsorship by a PI) within the UM-System. **Hellbender** is the latest High Performance Computing (HPC) resource available to researchers and students (with sponsorship by a PI) within the UM-System.
  
-**Hellbender** consists of 222 mixed x86-64 CPU nodes providing 22,272 cores as well as 28 GPU nodes consisting of a mix of Nvidia GPU's (see hardware section for more details). Hellbender is attached to our Research Data Ecosystem ('RDE') that consists of 8PB of high performance and general purpose research storage. RDE can be accessible from other devices outside of Hellbender to create a single research data location across different computational environments.+**Hellbender** consists of 222 mixed x86-64 CPU nodes providing 22,272 cores as well as 40 GPU nodes consisting of a mix of Nvidia GPU's (see hardware section for more details).

 General access will be open to any research or teaching faculty, staff, and students for any UM system campus. General access is defined as open access to all resources available to users of the cluster at an equal fairshare value. This means that all users will have the same level of access to the general resource. General access will be open to any research or teaching faculty, staff, and students for any UM system campus.

-=== Hellbender Advanced: Priority Access === +
- +
-When researcher needs are not being met at the general access level, researchers may request an advanced allocation on Hellbender to gain priority access. Priority access will give research groups a limited set of resources that will be available to them without competition from  general access users. Priority Access will be provided to a specific set of hardware through a priority partition which contains these resources. This partition will be created, and limited to use by the user and their associated group. These resources will also be in an overlapping pool of resources available to general access users. This pool will be administered such that if a priority access user submits jobs to their priority access partition, any jobs running on those resources from the overlapping partition will be requeued and begin execution again on another resource in that partition if available, or return to wait in the queue for resources. Priority access users will retain general access status, fairshare will still play a part in moderating their access to the general resource. Fairshare inside a priority partition determine which user’s jobs are selected for execution next inside this partition. The jobs running inside this priority partition will also affect a user’s fairshare calculations even for resources in the general access partition. Meaning that running a large amount of jobs inside a priority partition will lower a user’s priority for the general resources as well. +

-=== Traditional Investment === +
- +
-Hellbender Advanced Allocation requests that are not approved for DRII Priority Designation may be treated as traditional investments with the researcher paying for the resources used to create the Advanced Allocation at the defined rate. These rates are subject to change based on the determination of DRII, and hardware costs.+

 Priority access resources will generally be made available from existing hardware in the general access pool and the funds will be retained for a future time to allow a larger pool of funds to accumulate for expansion of the resource. This will allow the greatest return on investment over time. If the general availability resources are less than 50% of the overall resource, an expansion cycle will be initiated to ensure all users will still have access to a significant amount of resources. If a researcher or research group is contributing a large amount of funding, it may trigger an expansion cycle if that is determined to be advantageous at the time of the contribution. Priority access resources will generally be made available from existing hardware in the general access pool and the funds will be retained for a future time to allow a larger pool of funds to accumulate for expansion of the resource.
