+Transfer of files between SRV and JET is **not** necessary. The file system is mounted on JET Nodes JET01/JET02 and vice versa. These mounted drives need to transfer the data via the network and latencies might be higher. Network connectivity between JET and Aurora can be 25Gbit/s.

+There are two different node architectures, which can be used to stir computation on a specific microarchitecture. There are 7 intel (*skylake*) and 10 amd (*zen4*) architecture nodes available. One can select these specific architecture by providing additional parameters (constraint) to a job:

 ### Job efficiency reports
 
 since 2024 there is a new feature that allows to check how well one's jobs ran and get information on the efficiency of the resources used. The report is available once the job has finished.
