- | * Current | + | All the GPU machines are at Malá Strana (not at Troja), so you should not use ''/ |
- | * 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. | + | - ''/ |

- | 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 had batch size 20). This way the results should be more representative of the power for each GPU. | + | The previous benchmark only compares the speed of processing units within the GPUs and do not take into account the size of memory.
