I'm trying to use the arria10 FPGA to run some simulations. Upon logging in through interactive mode using the command:
qsub -I -l nodes=1:fpga_runtime:ppn=2 -d .
I get this error as soon as it finishes logging in:
/var/spool/torque/mom_priv/prologue.d//100-resetpcie.prologue: line 6: /sys/bus/pci/devices/0000:5e:00.0/remove: Permission denied
I get the same error when trying to login through the `devcloud_login` tool.
The script `100-resetpcie.prologue` tries to do the following:
#!/bin/bash
# Resetting FPGA Device
for x in `lspci | grep -i accel | grep -i intel | awk {'print $1'}`
do
echo 1 > /sys/bus/pci/devices/0000:$x/remove && sleep 1 && echo "1" > /sys/bus/pci/rescan
done
presumably to make sure the device(s) can be accessed. Trying to run this manually gives me the same error "Permission denied" to access the file.
When I try to run a synthesised bitstream (which had run before just a few days ago), it hangs forever when trying to get the device and it takes a while to kill the job.
Has anyone faced this issue before? I think a system reset is needed to properly release the board or so, but I'm not sure how to go about it.
