bash-5.2# export TMPDIR=/tmp

So, let's prepare a script that performs the mini-init.

So, let's prepare a script that runs the SPEC mini.
|
||||
|
||||
The first benchmark to run is `600.perlbench_s` which seems to take 5338 seconds
|
||||
(1.5 h) to run. I configured the pipeline to stop as soon as we have 2 h of
|
||||
silence, but after 150 minutes (2.5 h) of execution time it has not finished yet.
|
||||
Not sure if something is wrong now. Maybe I can run vmstat a few times and see
|
||||
the mount points to check everything is correct.
|
||||
|
||||
I may want to also increase the RAM available, so we can potentially run other
|
||||
benchmarks too.
|
||||
|
||||
At some point we may want to be able to specify the bootcmd from fpgactl
|
||||
directly.
