| @lambday | lisitsyn: there? | 01:04 |
| lisitsyn | lambday: hey | 01:04 |
| @lambday | lisitsyn: how are things? :D | 01:05 |
| lisitsyn | lambday: fine | 01:05 |
| lisitsyn | what about you? | 01:05 |
| lisitsyn | currently mapreducing some stuff around :) | 01:05 |
| @lambday | lisitsyn: haha that's great! | 01:06 |
| @lambday | lisitsyn: I have been working on hypothesis testing a bit | 01:06 |
| @lambday | and lately (thanks to wu lin) doing some stuffs in linalg as well | 01:06 |
| lisitsyn | hmm cool | 01:06 |
| lisitsyn | I am on my way to refactor neural nets a bit | 01:07 |
| @lambday | lisitsyn: one thing I want your opinion on | 01:07 |
| lisitsyn | sure | 01:07 |
| @lambday | lisitsyn: check this benchmark https://github.com/shogun-toolbox/shogun/pull/2806 | 01:07 |
| @lambday | it comes from a discussion here https://github.com/shogun-toolbox/shogun/issues/2801 | 01:07 |
| lisitsyn | oh something big | 01:08 |
| @lambday | so long story short - | 01:08 |
| @lambday | wu lin was using linalg methods without specifying any backend | 01:08 |
| @lambday | and he's using SGMatrix | 01:08 |
| lisitsyn | okay I've seen there is a bug | 01:08 |
| lisitsyn | some forgotten loading right? | 01:09 |
| @lambday | so if someone sets viennacl for global backend, then we're doing all the CPU-GPU data transfer | 01:09 |
| @lambday | which stabs the performance at the heart | 01:09 |
| lisitsyn | yeah that's obvious | 01:09 |
| @lambday | lisitsyn: that is fixed - we just needed a variant that returned the result matrix/vector | 01:10 |
| @lambday | ok so what I was thinking is | 01:10 |
| @lambday | how about a cmake switch to make SGMatrix as GPU one shogun-wise? | 01:10 |
| @lambday | we can just inherit from a separate base | 01:10 |
| @lambday | based on some preprocessor flag | 01:11 |
| @lambday | that way, we can milk the performance boost to the fullest when GPU is used | 01:11 |
| @lambday | this is totally possible even now with explicitly using CGPUMatrix+ViennaCL backed | 01:11 |
| lisitsyn | hmm let me think | 01:12 |
| @lambday | but how about we use the same SGMatrix everywhere - with the backend changed in a switch | 01:12 |
| @lambday | I am mainly worried because you see in the benchmark the penalty is unbearable | 01:13 |
| lisitsyn | I see no crime in such switch for sure | 01:13 |
| lisitsyn | but I have doubts we can hide gpu | 01:13 |
| @lambday | but when we use GPU memory then gain makes me drool :D | 01:13 |
| lisitsyn | I mean you always have to care whether you transfer data or not | 01:13 |
| lisitsyn | btw check torch | 01:14 |
| lisitsyn | https://github.com/torch/torch7 | 01:14 |
| @lambday | lisitsyn: checking.. | 01:14 |
| lisitsyn | neural guys love to use it | 01:14 |
| @lambday | lisitsyn: what I was saying is something like | 01:14 |
| @lambday | struct CPUMatrix | 01:14 |
| @lambday | { | 01:15 |
| @lambday | } | 01:15 |
| @lambday | ; | 01:15 |
| @lambday | struct GPUMatrix {}; | 01:15 |
| @lambday | #ifdef USE_CPU | 01:15 |
| lisitsyn | oh you finally talk C++ now I understand ;) | 01:15 |
| @lambday | lol | 01:15 |
| @lambday | you got the idea | 01:15 |
| @lambday | so two bases | 01:15 |
| lisitsyn | can we get more flexible with less compile time stuff? | 01:16 |
| @lambday | what do you see the problem with that? | 01:16 |
| lisitsyn | I am a bit worried about switching everything | 01:16 |
| lisitsyn | I mean if sgmatrix is in gpu | 01:16 |
| lisitsyn | some stuff would break right? | 01:16 |
| @lambday | I'm thinking what would that be.. | 01:17 |
| lisitsyn | most of code is not written for gpu so we should expect bugs here | 01:17 |
| @lambday | well that makes sense.. | 01:18 |
| @lambday | so devs should explicitly use gpumatrix if they wanna use one.. | 01:19 |
| lisitsyn | lambday: it seems to me that sgmatrix should be kind of dynamic about that | 01:19 |
| lisitsyn | maybe there is some solution to make it a bit more dynamic | 01:19 |
| @lambday | lisitsyn: what do you mean by dynamic? | 01:19 |
| lisitsyn | like sometimes it is gpu but sometimes it is cpu | 01:19 |
| @lambday | lisitsyn: that's what I meant.. | 01:19 |
| @lambday | #ifdef USE_CPU | 01:19 |
| lisitsyn | I mean not globally | 01:19 |
| @lambday | lisitsyn: okay.. so some param | 01:20 |
| lisitsyn | well say in neural nets I have all these parameters in sgmatrix | 01:20 |
| lisitsyn | that's cool to have it as gpu matrix | 01:20 |
| lisitsyn | but some other algorithms do not expect gpu | 01:20 |
| @lambday | lisitsyn: yeah that makes sense... | 01:21 |
| lisitsyn | this doesn't fit your template linalg idea though | 01:21 |
| @lambday | lisitsyn: what I don't like is that now we have two different types of matrices | 01:21 |
| lisitsyn | that's ok they are really different | 01:21 |
| lisitsyn | it seems there is no magic to treat them in the same way | 01:21 |
| @lambday | yep.. apparently so :( | 01:22 |
| @lambday | in linalg we're anyway treating them differently | 01:22 |
| lisitsyn | yeah | 01:22 |
| lisitsyn | I think sgmatrix should be like tensor in torch | 01:22 |
| lisitsyn | they have some clean api it seems | 01:23 |
| lisitsyn | btw what about sgmatrix->sgtensor? ;) | 01:23 |
| @lambday | lol we do have that multidimensional array thing right? | 01:23 |
| @lambday | maybe make that more like tension | 01:23 |
| @lambday | oops | 01:23 |
| @lambday | tensor | 01:23 |
| @lambday | totally didn't mean tension :D | 01:24 |
| lisitsyn | hah | 01:24 |
| lisitsyn | that's actually super cool thing | 01:24 |
| lisitsyn | that they can generalize | 01:24 |
| lisitsyn | say you have RGB image | 01:24 |
| @lambday | I'm assuming that it is efficient as well | 01:24 |
| lisitsyn | and then you got RGB-D and its 3d | 01:25 |
| lisitsyn | nothing works | 01:25 |
| lisitsyn | :D | 01:25 |
| @lambday | voxels ? :D | 01:25 |
| lisitsyn | yeah like these | 01:25 |
| lisitsyn | and when aliens get control of humanity | 01:25 |
| lisitsyn | we get to 4d | 01:25 |
| lisitsyn | would be bad to rewrite code again | 01:26 |
| @lambday | gotta check it then! | 01:26 |
| lisitsyn | aha | 01:26 |
| lisitsyn | ohh these MR tasks go so slow | 01:27 |
| @lambday | it's in C ! | 01:27 |
| lisitsyn | yeah lua + C | 01:27 |
