weather satellite loop slow and jumpy: how to monitor gpu load?

[home user]

background:
Earlier today, I was trying to view a loop of weather satellite images.  The animation
speed was set to default, which is about midway between slowest and fastest.  But the
images were inappropriately slow to load, and the animation was inappropriately slow to
advance from frame to frame.  I experience this a lot.  My desktop has an nVidia GeForce
GTX 660/PCIe/SSE2, and I'm using the driver that's from rpmfusion, *not* from
nVidia (I don't remember what it's called) proprietary one.

questions:
I've seen somewhere, I don't remember where, that there is a way of monitoring the
gpu's busyness or load.  I sure would like to be able to do this.  I'd like
something similar to the cpu plot and process table of "KSysGuard".  What
tool(s) come packaged with Fedora (27) to do this?  If none, what is available in the
usual Fedora repositories for this?

The driver from rpmfusion *is the same* as that from nVidia.  All that rpmfusion does
is package it in an easy to install and maintain way.

Just so others can check, maybe tell the web site you're accessing?

My real desire here is to have a gpu monitor.  These weather satellite loops are not the
only reason for wanting this.  But the loops are an easy demonstration of where a gpu
monitor really would be nice to have available.

The url is:
http://rammb-slider.cira.colostate.edu/?sat=goes-16&sec=full_disk&...

The satellite can be set to either GOES-East (GOES-16) or Himawari-8.
I usually click the "Zoom (+)" either once or twice.
For "Product", I most often choose "RGB Air Mass (EUMETSAT)".

The RGB Air Mass is not imaged by the satellite.  Rather it is derived (calculated) from
four other bands that are imaged by the satellite.  I do not know if that math is done by
the host or on my workstation.

The reason I asked about the site was two-fold.  Always nice to have another weather
satellite site, especially during typhoon season.  And, my system happens to run the
rpmfusion/nVidia drivers and my card is a GeForce GTX 660.  akmod-nvidia-390.59-1 is
the current driver.

Viewing that site within Chrome on F28/KDE is smooth at all speeds and all products
for me.

I really wouldn't expect a site such as that to be much of a gpu hog.  I think it
just downloads a series of images and then loops through them.  I would think that
watching a high-def movie with lots of action would be more of a strain on the gpu.

Anyway, I suppose I would check the nVida site to see if they have tools since you
are using their gpu and driver.

Oh, and thanks for the weather site.  :-)

I noticed that a large area of convective clouds east of the northern-most part of the
Philippines has developed a little "twist" and shows good upper level
divergence.  The Joint Typhoon Warning Center (JTWC) seems to think it will become a
tropical cyclone soon.  Better keep an eye on it!  If you need the URL of the JTWC, let me
know.  The site I gave you is by "CIRA", a research institute at Colorado State
U. in Fort Collins, Colorado.  The site is currently "beta", and sometimes gets
somewhat behind data-wise.

I'll try to check the nVidia site tomorrow.  It's late here now.

I've had JTWC bookmarked for years now.  As well as Tropical Storm Risk.

For my area, Himawari is best and they have their own site. 
http://www.data.jma.go.jp/mscweb/data/himawari/sat_img.php?area=se2 

You should try that site and see if it performs well or not for you.  I've written
scripts that download the images on a daily basis and make them into movies when
typhoons hit Taiwan.  :-)

Good luck

I saw the same issues with the JMA site that I saw with the CIRA site.  I don't know
if it's relevant, but I use Firefox, not chrome.

I did not find any GPU monitors in the nVidia site.  But the CPU monitors I have did not
come from Intel, they came packaged with Fedora or its desktop managers (Gnome, KDE,
etc.).  Thus my hope that some member of this list knows of a GPU load/performance monitor
for Linux.  I didn't see any in "apper" or "software".

The jma site does have some good training materials, and I've been wanting to learn
more about the RGB Air Mass product.  Thank-you, Ed, for pointing me to that site.  Now if
only I could find a site with free, high quality, high resolution isentropic analysis
covering at least all of North America!  I see that the cloud cluster I mentioned
yesterday, now a tropical storm, is currently forecast to not bother Taiwan.

Yes, it is relevant.  I just now tried the RAMMB site in firefox and it is
experiencing issues.  Although the slider is moving at its normal pace, only the
first and last images are being flashed on the screen.  Refreshing the page makes it
work OK for a moment but then it results in similar wonkiness.  Chrome is working
just fine.

So, suggest you give another browser a try.  :-)

Yep, no stormy weather for us this time.

The looping working fine in one browser but not another suggests (to me) a problem with
the other browser rather than the web site or my gpu.  So I will try to have some e-mail
conversation with the slider's lead developer (I've had e-mail discussions with
him before).  I hope to get adequate information from him to submit a good bug against
Firefox.  This is likely to take a while.  If and when I submit a bug, I'll post its
number here.

Not exactly like the Ksysguard plot(s), but try nvidia-settings, the
thermal settings tab should give an indication of the current load on
the GPU.

Thank-you, Ahmad.  I tried it while watching a yangqin troupe video (some very fast
playing) and a pipe organ video (camera man moved around a lot while shooting the organist
playing the organ) as well as while the loop of weather satellite images was loading and
playing.  What I find most useful there is what's displayed when I select what on my
workstation is:
a. the 4th main line ("GPU 0 - (GeForce GTX 660)"), and
b. the second sub-entry of (a) ("PowerMizer").
You're right - not exactly like the KSysGuard plots.  Also no process-specific
information like what KSysGuard offers.

Question: How do I make suggestions for new Fedora applications or tools?  (I realize the
suggestions might get passed on to other software projects like KDE, Gnome, etc.)
