-* [[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)]]+In this section will be explained how to use cluster properly.  
 +==== TensorFlow Environment ====
  
-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)+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.

 +  export PATH=/a/merkur3/kocmanek/ANACONDA/bin:$PATH
  
-===== Installed toolkits =====+And then you can activate your environment:
  
-//This should mention where each interesting toolkit lives (on a particular machine).//+  source activate tf1 
 +  source activate tf1cpu
  
-==== TensorFlow ====+This environment have TensorFlow 1.0 and all necessary requirements for NeuralMonkey.
  
-[[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>+==== Using cluster ====
  
-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`+Rule number one, always use the GPU queue (never log in machine by ssh). Always use qsub or qsubmit with proper arguments.
  
-=== Select GPU device ===+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.
  
-Use variable CUDA_VISIBLE_DEVICES to constrain tensorflow to compute only on the selected one. For the use of first GPU use: +  qrsh -q gpu.q -l gpu=1 -pty yes bash 
-<code>export CUDA_VISIBLE_DEVICES=0</code>+   
 +For running experiments you must use qsub command:
  
-To list available devices, use: +  qsub -q gpu.q -l gpu=1,gpu_cc_min3.5=1,gpu_ram=2G WHAT_SHOULD_BE_RUN 
-<code>/opt/cuda/samples/1_Utilities/deviceQuery/deviceQuery | grep ^Device</code>+   
 +Cleaner way to use cluster is with /home/bojar/tools/shell/qsubmit
  
-===== Basic commands =====+  qsubmit --gpumem=2G --queue="gpu.q" WHAT_SHOULD_BE_RUN 
 +   
 +It is recommended to use priority -100 if you are not rushing for the results and don't need to leap over your colleagues jobs.
