Folding Forum

Right after I installed FAHClient and FAHControl I started folding with CPU and it worked great. I went over to the configuration and changed the slot with CPU to GPU. Now it wont fold at all. Status moves between Ready and Running for a while then settling on Error.

This keeps filling my log every time it switches between Ready and Running.

Welcome to the folding support forum.

The message "Bad platformId size" usually indicates that you are either using the generic Linux video drivers, or have not fully installed the proprietary nVidia drivers. GPU folding on Linux systems requires the nVidia drivers be installed along with the OpenCL support.

I have actually installed the nvidia drivers 361.48 and I have blacklisted nouveau
modprobe.d/nvidia-default.conf:blacklist nouveau

Using OpenSUSE Leap 42.1 and installed the nvidia driver through repository from nvidia
ftp://download.nvidia.com/opensuse/leap/42.1/

Posted: **Tue Apr 19, 2016 3:45 pm**

The OpenCL portion of the driver is sometimes packages separately. Check the repository.

Posted: **Tue Apr 19, 2016 4:11 pm**

There are no OpenCL packages in the repository from Nvidia.
However I do have the following package that does seem to contain support for OpenCL

Information for package nvidia-computeG04:

you may want to look at ocl-icd:

I cannot install libOpenCL as it conflicts with nvidia-computeG04

personally i would at least try ocl-icd. this is what it takes to get folding@home working on fedora which is also a rpm distribution. you can always reinstall the driver if it doesn't work. just my opinion though do what you are comfortable with.

Posted: **Tue Apr 19, 2016 5:41 pm**

Installing libOpenCL had no affect. Got same problem when folding with GPU.

Posted: **Tue Apr 19, 2016 6:06 pm**

after installing the NVidia driver did you do a "sudo halt" and power the machine back on after halting? rebooting after NVidia install is a necessary step. also exactly which gpu are you trying to fold with? is it supported? (to find out if its supported check GPU.txt)

if that doesn't work try deleting the slot and setting it up properly with FAHControl. you may want to post your config.xml file.

I have just reinstalled the nvidia driver, rebootet the machine.

I found my Nvidia graphic card in GPUs.txt
djviking@mintaka:/var/lib/fahclient> less GPUs.txt | grep "650 Ti"
0x10de:0x11c2:2:3:GK106 [GTX 650 Ti Boost]
0x10de:0x11c3:2:3:GK106 [GeForce GTX 650 Ti]
0x10de:0x11c6:2:3:GK106 [GeForce GTX 650 Ti]

I have now also tried to remove the old slot and created a new gpu slot. Values for gpu core, opencl and cuda was set to -1. That didn't work. Still getting the problem.

Where is this config.xml located?

Posted: **Tue Apr 19, 2016 6:45 pm**

my config.xml is located in my home directory at ~/fahclient_7.4.4-64bit-release/config.xml though it may be slightly different on opensuse. GPU.txt should be in the same folder. though to be honest i really think you need ocl-icd. now that you have rebooted it may be a good time to try it.

Posted: **Tue Apr 19, 2016 7:05 pm**

I have already tried with installing libOpenCL (ocl-icd).

I have nothing of fahclient under my home directory.
However I did find a bunch of configs in /var/lib/fahclient/configs/

This on is config-20160419-183935.xml

Code: Select all

<config>
  <!-- Network -->
  <proxy v=':8080'/>

  <!-- Remote Command Server -->
  <password v='******************'/>

  <!-- User Information -->
  <passkey v=''/>
  <team v='37651'/>
  <user v='DJViking'/>

  <!-- Folding Slots -->
  <slot id='0' type='GPU'>
    <paused v='true'/>
  </slot>
</config>

But I guess it is the /etc/fahcontrol/config.xml that is relevant here.

Code: Select all

<config>
  <!-- Network -->
  <proxy v=':8080'/>

  <!-- Remote Command Server -->
  <password v='*************'/>

  <!-- User Information -->
  <passkey v=''/>
  <team v='37651'/>
  <user v='DJViking'/>

  <!-- Folding Slots -->
  <slot id='0' type='GPU'>
    <paused v='true'/>
  </slot>
</config>

Passkey removed. ~sortofageek

Unless you know those new index values to be accurate, you will have made the troubleshooting much more difficult. The index settings are not the issue. Please return them to their default values.

that was before you rebooted. its fine with me if you don't want to but, i think you will continue to see "BadPlatformID" if you don't. have you installed the xorg-x11-drv-nvidia-*.rpm's? is the kernel module properly installed? how was the driver installed? i checked the page https://en.opensuse.org/SDB:NVIDIA_drivers and it says the following:

The packages contain the correct 'supplements:' so Zypper will find the correct modules for your card. Unfortunately on openSUSE Leap 42.1 these 'supplemements' are being ignored by default by YaST (boo#953522). Therefore you need to select 'Extras/Install All Matching Recommended Packages' in 'Software Management' for autoselection and installation of the appropriate NVIDIA driver packages. When using 'zypper inr' you're not affected by this issue on openSUSE Leap 42.1.

other than that i am out of ideas.
