I cannot control jtop on page 4MEM to alter the swap file on Jetson NX #65

Closed Philliec459 closed 4 years ago

Philliec459 commented 4 years ago

Describe the bug I have been running jtop for about 2 weeks now on my Jetson NX on Jetpack 4.3. It works great, but on the 4MEM page I now have no control of the swap space. I could swear in the beginning I could change the swap file size and enable/disable, but now I cannot get out of Extra/Swap and Status/Enabled. I now have a 8GB swap file and 4GB of zram working with 6 CPU's. I have tried to cut back on the swap file to 4GB, but I can't seem to make any changes.

I have tried sudo jtop --restore , but that did not help.

I would appreciated any advice on how to handle this.

I uninstalled jtop and then got rid of the swap file per the following link:

https://stackoverflow.com/questions/43301858/how-to-delete-swap-file-in-ubuntusudo

swapoff -a -v sudo rm /swapfile

back up /etc/fstab:

sudo cp /etc/fstab /etc/fstab.bak sudo sed -i '/\/swapfile/d' /etc/fstab

I then reinstalled jetson_stats and now I am back to normal with Extra Swap disabled and page 4MEM looking like it did before.

Hi @Philliec459 ,

I apologise for my late reply. Yes, you follow a proper way to disable the swap, you can use as well another tool already included in jetson-stats.

jetson_swap -d [directory] -n [name] --off

Will do the same line that you post

Can send me next time a screenshot, if you have again this bug? I would like to fix, but I can't reproduce otherwise.

Thank you.

I think the problem is that I have added a SSD and everything is now on SSD exept for what is needed to boot from micro SD card.

In the process on the old SD was a swfile swapfile. jtop was looking at that and not the swapfile on the SSD. Once deleting the swfile on the SD jtop is behaving properly. However, if I do create an Extra Swap with jtop, will jtop be looking just at the SD card for a swap file or can we direct it to look at the new SSD card?

One other question. I love having access to the fan speed in jtop especially while training a model. Sometimes at the end of training the fan will automatically switch to 0. I am glad I have jtop to observe this, but is there a way to have the fan speed adhere to what we have in jtop?

I have now used jtop to add an additional 2GB of swap space and it is called swfile. jtop configured it for the new SSD (vs. the micro SD card that I still need to boot from). I used page 4MEM and clicked on 's' and it did disable the swap file and gave me the proper display to re-Enable swap and set the size of the swap file. This all working properly on the new SSD too. Thank you.

However, if I do create an Extra Swap with jtop, will jtop be looking just at the SD card for a swap file or can we direct it to look at the new SSD card?

I need to make a setup to test it. I can't reply right now, but I will check

I think depends if jetson_clocks is disabled from another script

Thank you for your reply. Jtop and the swap file are all working fine now that I removed the swfile from the micro SD card and now jtop’s swfile is on the SSD. It should be faster that way too.

I think you are right about jetson_clocks. During the etreme training the CPUs are running at 1.4Hz and at the end go back to 1.2Hz. This is when the fan turns off.
