-=== Individual acquisitions:​ NVIDIA Academic Hardware Grants ==+Multiple versions of CUDA library are accessible on each machine together with cudnn. Theano and TensorFlow is supported.
  
-There is an easy way to get one high-end GPU: [[https://developer.nvidia.com/academic_gpu_seeding|ask NVIDIA for an Academic Hardware Grant]]All it takes is writing a short grant application (at most ~2 hrs of work from scratch; if you have a GAUK, ~15 minutes of copy-pasting)Due to the GPU housing issues (mainly rack space and cooling), Milan Fsaid we should request the Tesla-line cardsIf you want to have a look at an application,​ feel free to ask at hajicj@ufal.mff.cuni.cz ​:)+[[http://ufaladm2.ufal.hide.ms.mff.cuni.cz/munin/ufal.hide.ms.mff.cuni.cz/​lrc-master.ufal.hide.ms.mff.cuni.cz/​index.html#​dll|GPU usage rolling graphs]]
  
-Take care, however, to coordinate the grant applications a little, so that not too many arrive from UFAL within a short time: these grants are explicitly //not// intended to build GPU clusters, they are "​seeding"​ grants meant for researchers to try out GPUs (and fall in love with them, and buy a cluster later). If you are planning to submit the hardware grant, have submitted one, or have already been awarded one, please add yourself here. 
  
-Known NVIDIA Academic Hardware Grants:+===== Rules ===== 
 +  * First, read [[internal:Linux network]] and [[:​Grid]]. 
 +  * All the rules from [[:Grid]] apply, even more strictly than for CPU because there are too many GPU users and not as many GPUs available. So as a reminder: always use GPUs via ''​qsub''​ (or ''​qrsh''​),​ never via ''​ssh''​. You can ssh to any machine e.g. to run ''​nvidia-smi''​ or ''​htop'',​ but not to start computing on GPU. Don't forget to specify you RAM requirements with e.g. ''​-l mem_free=8G,​act_mem_free=8G,​h_data=12G''​. 
 +    * **Note that you need to use ''​h_data''​ instead of ''​h_vmem''​ for GPU jobs.** CUDA driver allocates a lot of "​unused"​ virtual memory (tens of GB per card), which is counted in ''​h_vmem'',​ but not in ''​h_data''​. All usual allocations (''​malloc'',​ ''​new'',​ Python allocations) seem to be included in ''​h_data''​. 
 +  * Always specify the number of GPU cards (e.g. ''​gpu=1''​) and your GPU memory requirements (e.g. ''​gpu_ram=2G''​). Thus e.g. <​code>​qsub -q '​gpu*'​ -l gpu=1,​gpu_ram=2G</​code>​ 
 +  * If you need more than one GPU card (on a single machine), always require at least as many CPU cores (''​-pe smp X''​) as many GPU cards you need. E.g. <​code>​qsub -q '​gpu*'​ -l gpu=4,​gpu_ram=7G -pe smp 4</​code>​ 
 +  * For interactive jobs, you can use ''​qrsh'',​ but make sure to end your job as soon as you don't need the GPU (so don't use qrsh for long training). **Warning: ''​-pty yes bash -l''​ is necessary**,​ otherwise the variable ''​$CUDA_VISIBLE_DEVICES''​ will not be set correctly. E.g. <​code>​qrsh -q '​gpu*'​ -l gpu=1,​gpu_ram=2G -pty yes bash -l</​code>​In general: don't reserve a GPU (as described above) without actually using it for longer time. (E.g. try separating steps which need GPU and steps which do not and execute those separately on our GPU resp. CPU cluster.) Ondřej Bojar has a script /​home/​bojar/​tools/​servers/​watch_gpus for watching reserved but unused GPU on most machines which will e-mail you, but don't rely on it only. 
 +  * Note that the dll machines have typically 10 cards, but "​just"​ 250 GB RAM (DLL7 has only 128 GB). So the expected (maximal) ''​mem_free''​ requirement for jobs with 1 GPU is 25GB. If your 1-GPU job takes e.g. 80 GB and you submit three such jobs on the same machine, you have effectively blocked the whole machine and seven GPUs remain unused. If you really need to submit more high-memory jobs, send each on a different machine. 
 +  * If you know an approximate runtime of your job, please specify it with ''​-l s_rt=hh:​mm:​ss''​ - this is a soft constraint so your job won't be killed if it runs longer than specified. It will help SGE to better schedule the jobs, especially multi-gpu reservations (see ''​qconf -ssconf''​).

The GPU environment can be loaded by calling <​code>​source tf-gpu/​bin/​activate-gpu</​code>​+You need to set library path from your ''​~/.bashrc''​:
  
-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`+  CUDA_version=10.

 +  * Note that the ''​cudnn''​ library is compiled for specific version of ''​cuda''​. If you need specific version of ''​cudnn'',​ you can look in ''/​opt/​cuda/​$CUDA_version/​cudnn/''​ whether it is available for a given ''​$CUDA_version''​.
  
-Use variable CUDA_VISIBLE_DEVICES to constrain tensorflow to compute only on the selected one. For the use of first GPU use: 
-<​code>​export CUDA_VISIBLE_DEVICES=0</​code>​ 
  
-===== Basic commands ​=====+==== TensorFlow Environment ==== 
 + 
 +Many people at UFAL use TensorFlow. To start using it it is recommended to create a [[python|Python virtual environment]] (or use Anaconda for it). Into the environment you must place TensorFlow. The TF is either in CPU or GPU version. 
 + 
 +  pip install tensorflow 
 +  pip install tensorflow-gpu 
 +   
 +You can use prepared environment by adding into your ~/.bashrc 
 + 
 +  export PATH=/​a/​merkur3/​kocmanek/​ANACONDA/​bin:​$PATH 
 + 
 +And then you can activate your environment:​ 
 + 
 +  source activate tf18 
 +  source activate tf18cpu 
 + 
 +This environment have TensorFlow 1.8.0 and all necessary requirements for NeuralMonkey. 
 + 
 +==== Pytorch Environment ==== 
 + 
 +If you want to use pytorch, there is a ready-made environment in 
 + 
 +  /​home/​hajicj/​anaconda3/​envs/​pytorch/​bin 
 +   
 +It does rely on the CUDA and CuDNN setup above. 
 + 
 +==== Using cluster ==== 
 + 
 +As an alternative to ''​qsub'',​ you can use /​home/​bojar/​tools/​shell/​qsubmit 
 + 
 +  qsubmit --gpumem=2G --queue="​gpu-ms.q"​ WHAT_SHOULD_BE_RUN 
 +   
 +It is recommended to use priority lower than the default -100 if you are not rushing for the results and don't need to leap over your colleagues jobs. Please, do not use priority between -99 to 0 for jobs taking longer than a few hours, unless it is absolutely necessary for your work.

 +=== Select GPU device ===
 +
 +The variable CUDA_VISIBLE_DEVICES constrains tensorflow and other toolkits to compute only on the selected GPUs. **Do not set this variable yourself** (unless debugging SGE), it is set for you automatically by SGE if you ask for some GPUs (see above).
 +
 +To list available devices, use:
 +  /​opt/​cuda/​samples/​1_Utilities/​deviceQuery/​deviceQuery | grep ^Device

 +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). The benchmark uses 2GB model of seq2seq machine translation in Neural Monkey (De > EN). If not specified, the benchmark had an access only to one GPU.

 +=== Second Benchmark ===
 +
 +The previous benchmark only compares the speed of processing units within the GPUs and do not take into account the size of memory. Therefore I have conducted another benchmark, this time for each graphic card I have increased the batch size as much as possible so the model still could fit into the GPU (the previous benchmark model had batch size 20). This way the results should be more representative of the power for each GPU.

 +==== Individual acquisitions:​ NVIDIA Academic Hardware Grants ====
 +
 +There is an easy way to get one high-end GPU: [[https://​developer.nvidia.com/​academic_gpu_seeding|ask NVIDIA for an Academic Hardware Grant]]. All it takes is writing a short grant application (at most ~2 hrs of work from scratch; if you have a GAUK, ~15 minutes of copy-pasting). Due to the GPU housing issues (mainly rack space and cooling), Milan F. said we should request the Tesla-line cards (2017; check with Milan about this issue). If you want to have a look at an application,​ feel free to ask at hajicj@ufal.mff.cuni.cz :)
 +
 +Take care, however, to coordinate the grant applications a little, so that not too many arrive from UFAL within a short time: these grants are explicitly //not// intended to build GPU clusters, they are "​seeding"​ grants meant for researchers to try out GPUs (and fall in love with them, and buy a cluster later).
