 ## Deploying on the ETHZ HACC-cluster 
-The ETHZ HACC is a premiere cluster for research in systems, architecture and applications (https://github.com/fpgasystems/hacc/tree/main). Its hardware equipment provides the ideal environment to run Coyote-based experiments, since users can book up to 10 servers with U55C-accelerator cards connected via a fully switched 100G-network. User accounts for this platform can be obtained following the explanation on the previously cited homepage.

-The interaction with the HACC-cluster can be simplified by using the sgutil-run time commands. They also allow to easily program the accelerator with a Coyote-bitstreamd and insert the driver. For this purpose, the script `program_coyote.sh` has been generated. Under the assumption that the hardware-project has been created in `examples_hw/build` and the driver is already compiled in `driver`, the workflow should look like this:

 If the driver insertion went through, the last printed message should be `probe returning 0`. Furthermore, the dmesg-printout should contain a line `set network ip XXXXXXXX, mac YYYYYYYYYYYY`, which displays IP and MAC of the Coyote-NIC if networking has been enabled in the system configuration. 
 
+To program Coyote to a remote server, `util/program_hacc_remote.sh` may be used in the same way. Additionally, that script will ask for a list of server ids (e.g., `3, 5`).
