-bla bla+In this section will be explained how to use cluster properly.  
 +==== TensorFlow Environment ====
  
-===== Performance tests =====+Majority people at UFAL use TensorFlow. To start using it you need to create python virtual environment (virtualenv or use Anaconda for it). Into the environment you must place TensorFlow. The TF is either in CPU or GPU version.
  
-* [[http://www.trustedreviews.com/nvidia-geforce-gtx-1080-review-performance-benchmarks-and-conclusion-page-2| 980 vs 1080 vs Titan X (not the Titan Z we have)]]+  pip install tensorflow 
 +  pip install tensorflow-gpu 
 +   
 +You can use prepared environment by adding into your ~/.bashrc
  
-In the following table is the experiment conducted by Tom Kocmi. You can replicate experiment: /a/merkur3/kocmanek/Projects/GPUBenchmark (you will need to prepare environment of TensorFlow11 or use my ANACONDA)+  export PATH=/a/merkur3/kocmanek/ANACONDA/bin:$PATH

-===== Installed toolkits =====+This environment have TensorFlow 1.0 and all necessary requirements for NeuralMonkey.
  
-//This should mention where each interesting toolkit lives (on a particular machine).//+==== Using cluster ====
  
-==== TensorFlow ====+Rule number one, always use the GPU queue (never log in machine by ssh). Always use qsub or qsubmit with proper arguments.
  
-[[https://redmine.ms.mff.cuni.cz/projects/mmmt/repository/revisions/6a064187fc6959db9b77cf2d5350c5f4918a8067/entry/prepare_env.sh|This script]] installs TensorFlow 0.7.1 (and all other dependencies we need for Multimodal Translation) into `tf' and `tf-gpu' virtual environments. The GPU environment can be loaded by calling <code>source tf-gpu/bin/activate-gpu</code>+For testing and using the cluster interactively you can use qrsh (this should not be used for long running experiments since the console is not closed on the end of the experiment). Following command will assign you a GPU and creates interactive console.
  
-OP: I created [[https://gist.github.com/oplatek/323b63b8f116cd3d78c0f492f78cc289|script]] which install Tensorflow 0.8 and test it if it uses GPU. TF is installed into `user` or `global` installation either for `python3.4` or `python2.7`+  qrsh -q gpu.q -l gpu=1 -pty yes bash 
 +   
 +For running experiments you must use qsub command:
  
-=== Select GPU device ===+  qsub -q gpu.q -l gpu=1,gpu_cc_min3.5=1,gpu_ram=2G WHAT_SHOULD_BE_RUN 
 +   
 +Cleaner way to use cluster is with /home/bojar/tools/shell/qsubmit
  
-Use variable CUDA_VISIBLE_DEVICES to constrain tensorflow to compute only on the selected one. For the use of first GPU use: +  qsubmit --gpumem=2G --queue="gpu.q" WHAT_SHOULD_BE_RUN 
-<code>export CUDA_VISIBLE_DEVICES=0</code> +   
- +==== Basic commands ====
-To list available devices, use: +
-<code>/opt/cuda/samples/1_Utilities/deviceQuery/deviceQuery | grep ^Device</code> +
