How to install clBLAS from the ppa about broccoli

[wanderine]

You don't need to install clBLAS, you just need to set the environment
variable LD_LIBRARY_PATH

e.g.

export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/andek/BROCCOLI/code/BROCCOLI_LIB/clBLASLinux

I tried the .deb file but it said dependency not satisfied in synaptics
package manager. I am not very familiar with ubuntu so I would rather no go
through the cmake route. Just seems too much. Something like apt-get would
be great for me.
Thank you

Thanks that worked. But the GetOpenCLInfo still doesnt recognize my NVIDIA card. I did install libcuda1-355, nvidia-355, nvidia-opencl-icd-355 but still its not showing up.

[wanderine]

Try

Sudo nvidia-xconfig

And then reboot

Did that it said writing to new conf file in X11 folder or something but still it doesn't show up

[wanderine]

Try

sudo apt-get purge nvidia*

sudo apt-get install nvidia-current

Still same problem. I must say that I had installed linux-generic before I got you reply. I was reading some forums

[wanderine]

OK this is my last tip

sudo rm .xsession-errors*

Otherwise

sudo apt-get purge nvidia*

sudo apt-get update

sudo apt-get dist-upgrade

sudo apt-get install nvidia-current

Thanks for the help. Reinstalling nvidia-346 got my desktop back again ... nvidia-current installs 304 version hence the problem. Running GetOpenCLInfo still doesn't recognize my card which is a gtx 980 ti. I guess I will try googling it. Thanks again.

[wanderine]

Tomorrow I will try to fix the CPU problem(s), so you can use that at least.

The CPU is running fine for me ... or atleast I think. I tried first level analysis it ran for some time before I quit seeing it was not using my GPU.

[wanderine]

Confused you with another user, sorry.

Can you check if this file exists?

/etc/OpenCL/vendors/nvidia.icd

Yes it does along with amdocl32.ocd and amdocl64.icd

[wanderine]

Found this

Here is a list of all of the packages you will need to get OpenCL working
on Ubuntu 14.10 with NVIDIA drivers:

sudo apt-get install nvidia-331 nvidia-331-uvm nvidia-opencl-dev nvidia-modprobe

EDIT: In case anyone encounters a similar problem on Ubuntu 15.04 and the
NVIDIA 346.59 drivers, the command to fix the issue is nearly identical:

sudo apt-get install nvidia-346 nvidia-346-uvm nvidia-opencl-dev nvidia-modprobe

Both didnt work for me. sudo clinfo didnt show the nvidia card.

The following will work if you use gtx 980 ti
sudo apt-get install nvidia-352 nvidia-352-uvm nvidia-opencl-dev nvidia-modprobe

Now clInfo recognised my nvidia card but GetOpenCLInfo didnt yet work.

[wanderine]

OK can you just make a reboot to make sure everything is loaded from start.

Lol now after restart even clInfo doesn't recognize the video card.

[wanderine]

Hmm, can you do

sudo clinfo

and then

clinfo

and

sudo GetOpenCLInfo

and then

GetOpenCLInfo

sudo doesnt recognize the LD_LIBRARY_PATH

[wanderine]

Try

sudo export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/andek/BROCCOLI/
code/BROCCOLI_LIB/clBLASLinux

Also see end of this page, suppose you need to change 331 to 352

I finally added the next lines in my /etc/rc.local file:

begin opencl config

modprobe nvidia-331-uvm
mknod -m 666 /dev/nvidia-uvm c 249 0
clinfo

end opencl config

says sudo export command not found

[ImmanuelSamuel]

$ modprobe nvidia-352-uvm
modprobe: ERROR: could not insert 'nvidia_352_uvm': Operation not permitted

[wanderine]

try with sudo

$ sudo modprobe nvidia-352-uvm
$ sudo mknod -m 666 /dev/nvidia-uvm c 249 0

sudo clinfo

Then try clinfo and GetOpenCLInfo without sudo

$ sudo modprobe nvidia-352-uvm
$ sudo mknod -m 666 /dev/nvidia-uvm c 249 0
$ sudo clinfo

The above worked but without sudo nope

[wanderine]

Can you now see the device in GetOpenCLInfo?

If you want to make the change permanent, open /etc/rc.local with a text
editor,

e.g.

gedit /etc/rc.local

or

sudo gedit /etc/rc.local

add

begin opencl config

modprobe nvidia-331-uvm
mknod -m 666 /dev/nvidia-uvm c 249 0
clinfo

end OpenCL config

then save the file

2015-08-15 22:44 GMT+02:00 ImmanuelSamuel [email protected]:

$ sudo modprobe nvidia-352-uvm
$ sudo mknod -m 666 /dev/nvidia-uvm c 249 0

Ok so both clinfo and GetOpenCLInfo works (without sudo) if I put it in the .bashrc in my home directory i.e. recognises the video card. But it doesnt work in a terminal. I added your previous message in /etc/rc.local but that also didnt do anything (yes I changed the version 331 to 352). Going to do a reset and see if anything changed.

[ImmanuelSamuel]

Nothing changed.

[wanderine]

Hmm, but GetOpenCLInfo now prints the 980 card? Can you try to for example
run RegisterTwoVolumes?

You need sudo if you write the commands in a terminal, but not if you put
them in a text file.

If I enter the following in a terminal

GetOpenCLInfo or
sudo GetOpenCLInfo

It doesnt recognize the card.

But if I put GetOpenCLInfo in the .bashrc file in my home directory then it shows the nvidia card when it runs as soon as I open a terminal.

[wanderine]

First run this in a terminal

$ sudo modprobe nvidia-352-uvm
$ sudo mknod -m 666 /dev/nvidia-uvm c 249 0
$ sudo clinfo

then run GetOpenCLInfo in a terminal (without sudo)

2015-08-15 23:08 GMT+02:00 ImmanuelSamuel [email protected]:

If I do

GetOpenCLInfo or
sudo GetOpenCLInfo

It doesnt recognize the card.

But if I put GetOpenCLInfo in the .bashrc file in my home directory then
it shows the nvidia card.

Yes I entered that still it doesn't recognize it.

[wanderine]

OK can you also do

sudo apt-get install nvidia-opencl-icd-352

Will update after I try it

[ImmanuelSamuel]

Finally GetOpenCLInfo is working with that

[ImmanuelSamuel]

Thanks wanderine!!!!!

[wanderine]

Nice, I will try to add this to the documentation.
