OpenCl kernel error after amdstream upgrade

Hi,
I did a system upgrade and a dependency seems to be broken now:

  FATAL kernel error: Failed to load OpenCL kernel!

I am using the phoenix-miner-svn and amdstream from aur to do mathematic calculations with my GPUs (hd 5850) for mining bitcoins.

After the update from amdstream 2.4 to 2.5 the phoenix-miner can't load the OpenCL kernel anymore.
  ./clifo
show all my GPUs, so amdstream seems be be ok

It is a 64bit system.
Maybe the problem has another source, but I couldn't figure it out.

  sudo phoenix-miner
returns the same failure.

Anyone an idea?

Re: OpenCl kernel error after amdstream upgrade

Which libcl do you use?
If unsure, issue:

pacman -Q libcl libopencl

Re: OpenCl kernel error after amdstream upgrade

Hi,
thanks for answering:)

libopencl is not installed, should it?

python2-pyopencl (required by phoenix-miner-svn) and amdstream require libcl, which is version 1.0-1

If you wouldn't mind, you could test the phoenix-miner-svn
Just do:

python2 ./phoenix.py -u http://12a5o5fTSPgZQm1fpPkkFDZdDwVxoYdE3A:x@mining.eligius.st:8337  -k phatk DEVICE=0 VECTORS BFI_INT AGGRESSION=11 FASTLOOP=false WORKSIZE=256

DEVICE=0 should be your GPU

The latest version of the miner maybe has to be run as sudo, but for me it doesn't work neither...

Re: OpenCl kernel error after amdstream upgrade

I have checked the libraries:

[root@ArchLinux /]# file /opt/amdstream/lib/*
/opt/amdstream/lib/libamdocl64.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

[root@ArchLinux /]#

[root@ArchLinux /]# file /usr/lib/libOpenCL.so*

/usr/lib/libOpenCL.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped
[root@ArchLinux /]#

On a backup (amdstream 2.4) I found this dependencies. I think I set the link from /usr/lib/libOpenCL.so.1 to /apt/amdstream/lib/libOpenCL.so.1 myself but I think not for the other one...

[harm@ArchLinux ~]$ file /opt/amdstream/lib/*
/opt/amdstream/lib/libamdocl64.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

[harm@ArchLinux ~]$ file /usr/lib/libOpenCL.so*

/usr/lib/libOpenCL.so.1: symbolic link to `/opt/amdstream/lib/libOpenCL.so.1'
[harm@ArchLinux ~]$

Therefore I tried this, but had no success:

mv /usr/lib/libOpenCL.so /usr/lib/libOpenCL.so_bak
mv /usr/lib/libOpenCL.so.1_bak /usr/lib/libOpenCL.so.1_bak
ln -s /opt/amdstream/lib/libOpenCL.so /usr/lib/libOpenCL.so
ln -s /opt/amdstream/lib/libOpenCL.so.1 /usr/lib/libOpenCL.so.1

Re: OpenCl kernel error after amdstream upgrade

Ok, right now, I'm not on a machine with AMD GPU, I'll test the miner later...

To the libOpenCL.so:
that file is provided by both extra/libcl and libopencl from AUR. extra/libcl is nvidia version, libopencl (which also provides libcl) is an alternative the one from AMD (from amdstream).
This is done so that various SDKs can be installed at the same time. In your case, however, I recommend using libopnecl instead of libcl.
Just remove libcl with pacman -Rdd and install libopencl (it has the same source as amdstream, you may copy the source tgz over).

(I should probably put up a wiki page on this)

I know that you have tested this manually, but please do it one more time using libopencl. Also don't let too much orphaned files dwell in your system ;-)

Also, have a look at this: http://bitcointalk.org/index.php?topic=20489.0

Re: OpenCl kernel error after amdstream upgrade

Hi again:)
It is still not working...

That would be nice, thanks:) But don't stress yourself, my USB-backup pays itself off very well right now;)

Thanks for the command, was hesitating to do this;)
But unfortunately this didn't work...

/usr/lib/libOpenCL.so:   symbolic link to `libOpenCL.so.1'

Good idea:)!

do you have something specific in mind;)??

Also, have a look at this: http://bitcointalk.org/index.php?topic=20489.0

found this thread previously and tried it - though it doesn't make sens to me - didn't work:(

Re: OpenCl kernel error after amdstream upgrade

It works now, obviously it was not a problem of amdstream!

Today I did an update of:
community/python2-pytools 2011.3-1
community/python2-pyopencl 2011.1.2-2
community/opencl-headers 1.1.20110526-1

One of them fixed i think;)

But I have a high CPU load on the python processes: 17% instead of 0.6% - no good:-(

Tried with poclbm, but I got this again:

python2 poclbm/poclbm.py -d 0 http://user:password@bitcoin.host:8332
Traceback (most recent call last):
  File "poclbm/poclbm.py", line 3, in <module>
    from BitcoinMiner import *
  File "/home/teo/poclbm/BitcoinMiner.py", line 4, in <module>
    from log import *
ImportError: No module named log

With phoenix-miner I got this again:

[11/08/2011 22:58:07] FATAL kernel error: Failed to load OpenCL kernel!

Unfortunately this is with and without VECTORS, as was suggested in the thread linked above. And my CPU usage /when it worked last time / was around 100% per core per worker. I got two cards, so I always have more than 190% CPU usage /100% per core/.

There is one miner here /64bit/ called hashkill, but it isn't working right with my cards. But that will be not necessarily be the case with your card/s. You have to set the following:

export LD_LIBRARY_PATH=/opt/amdstream/lib #if you installed it from AUR 
sudo ./install.sh 
hashkill-gpu -p bitcoin user:password:bitcoin.server.com:port

Re: OpenCl kernel error after amdstream upgrade

Hmmm... I have a feeling the problem is somewhere in the python layer...

Although it could be amdsteam's fault too... there is one thing you can try:
In amdstream's PKGBUILD I removed all the custom architecture-resolution stuff
because on linux w/ package management it is seriously useless...
But some software might expect it be the way AMD made it, so you can try moving
libs to the x86 or x86_64 subfolder in /opt/amdstream/lib.
Don't forget to edit ICD file accordingly...

It's just a guess though... I honestly don't know why it doesn't work sometimes...

Tried that, but with no luck.

found mine and edited, but with no luck again

I guess there was a reason for the disappearing of poclbm in AUR. And cgminer returns:

[2011-08-11 23:53:40] Unable to open phatk110722.cl for reading
[2011-08-11 23:53:40] Unable to find VECTORSX in source
[2011-08-11 23:53:40] Failed to init GPU thread 0
[2011-08-11 23:53:40] Unable to open phatk110722.cl for readingSegmentation fault

And actually I'm out of options now That was the last miner in AUR.
cgminer works pretty well, but only for those who read it's manual

NOW cgminer must be executed in /usr/bin if mining by GPU.
It's a stupid bug which the author may fix later. 

EDIT: Now that's odd, I preinstalled amdstream just to be sure that everything is fine and now I got only one gpu device in clinfo...
