-Summary of future plans:
+Not used at the moment: GeForce GTX 570 (from twister2)
-  * Current Troja servers won't get any GPUs (the only option would be [[http://www.czc.cz/hp-quadro-k1200-4gb/171662/produkt?ppcbee-adtext-variant=Produkt%3B+kategorie+%2B+cena%3B+Pobo%C4%8Dky&gclid=CKbKkbrWrswCFQUq0wodHDELCw|Quadro K1200 4GB]], horribly cost-inefficient)
+All machines have CUDA8.0 and should support both Theano and TensorFlow.
-  * The old Quadro K2000 we have is a much more low end piece, so we can't test is in Troja.
-  * There is MetaCentrum which also has GPUs, so testing can be done there.
-  * It is impossible (wasteful in terms of space and forbidden by a dean regulation) to put non-rack machines to our servers rooms. So we won't be buying GeForce GTX 1080 (~20000CZK, out of stock now), for a non-rack machine since we most likely don't have any available.
-  * Yes, there are grant applications under review which include rack machines with GPUs, e.g. 5x2 or something like that; more will be known in 2017.
+=== Disk space ===
+All the GPU machines are at Malá Strana (not at Troja), so you should not use ''/lnet/tspec/work/'', but you should use:
+- ''/lnet/spec/work/'' (alias ''/net/work/'') - Lustre disk space at Malá Strana
+- ''/net/cluster/TMP'' - NFS hard disk for temporary files, so slower than Lustre for most tasks
+- ''/net/cluster/SSD'' - also NFS, but faster then TMP because of SSD

 ===== How to use cluster =====
-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)

-===== 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,gpu_ram=2G -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>
+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.
-To list available devices, use:
+==== Basic commands ====
-<code>/opt/cuda/samples/1_Utilities/deviceQuery/deviceQuery | grep ^Device</code>

+=== 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.
