running a program on AWS f1 instance

[AnouarNechi]

Hello I have read the instructions to work with openpiton on AWS f1 instance and I have some questions:
when is it possible to run a precompiled benchmark is necessary to be executed before uploading the OS or it does not matter?
to run a precompiled benchmark for example dhrystone can I use this instruction:
pitonstream -b f1 -d system dhrystone.riscv --core=ariane --precompiled ?
From where do I get the linux image to upload to openpiton design on F1 instance. What do you mean by $FILE_LOCATION in ./dma_os $FILE_LOCATION.

Hi Anouar!

1. If you just want to run benchmark - you dont have to load OS, you can run it with pitonstream
2. Yes, this should work. But you also need to specify the UART port in the command with -p flag, e.g. "-p pts/6"
3. You can download it from our website https://parallel.princeton.edu/openpiton/ .
   Hope this helps:)

Best,
Grigory

Thank you Grigory
In order to see the UART should I open another console to see the execution or the pitonstream command will open it automatically.
if not How can I connect a terminal console to UART
