| 09:57:22 | markusN: | hi arkygeek |
| 09:57:37 | arkygeek: | hi |
| 09:57:49 | markusN: | which Linux do you have? |
| 09:57:58 | arkygeek: | kubuntu intrepid |
| 10:00:12 | markusN: | I thought that Jachym made 6.4 binaries for that but cannot find them |
| 10:01:48 | arkygeek: | regardless of 6.2 or 6.4 on linux, it should not be that different should it |
| 10:01:58 | markusN: | besides the possibility to compile yourself ( http://grass.osgeo.org/wiki/Compile_and_Install#Ubuntu_7.10_64-bit ), perhaps the compiler optimization was different? |
| 10:02:00 | sigq: | Title: Compile and Install - GRASS-Wiki ( at grass.osgeo.org ) |
| 10:02:01 | arkygeek: | especially 6.4 being slower |
| 10:02:12 | markusN: | but only on Mac you say? |
| 10:02:17 | arkygeek: | i used binaries for bot installs |
| 10:02:34 | arkygeek: | i am running 6.4 on mac, 6.2 on linux |
| 10:02:43 | arkygeek: | s/bot/both |
| 10:02:45 | markusN: | I don't know if William uses optimization |
| 10:02:52 | arkygeek: | ahh |
| 10:03:14 | arkygeek: | that might be it then hey? |
| 10:04:11 | markusN: | according to grass64/macosx/ReadMe.rtf he doesn't |
| 10:04:37 | markusN: | http://trac.osgeo.org/grass/browser/grass/branches/develbranch_6/macosx |
| 10:04:38 | sigq: | Title: /grass/branches/develbranch_6/macosx - GRASS GIS - Trac ( at trac.osgeo.org ) |
| 10:04:42 | markusN: | just guessing |
| 10:04:53 | markusN: | best is to ask him via email |
| 10:05:05 | arkygeek: | so if i build it from source, it might be better |
| 10:05:08 | markusN: | aim is that 6.4 is *faster* than 6.2 |
| 10:05:17 | markusN: | and it is for r.cost, r.watershed etc |
| 10:05:37 | markusN: | maybe yes, then you know what compiler settings you prefer |
| 10:19:16 | markusN: | arkygeek: found it: grass-preview-doc_6.4~20081031-1_all.deb in http://les-ejk.cz/ubuntu/dists/intrepid/multiverse/binary-i386/, a bit old though |
| 10:19:27 | markusN: | will try to convince jachym to rebuild RC4 |
| 10:19:58 | arkygeek: | ok, I will watch for that... I don't need to run any more models for a while now, so can wait ;- ) |
| 10:20:28 | : | * arkygeek bookmarks the url |
| 10:21:33 | wildintellect: | hmm do those instructions talk about optimizations - I built the other day and seem to recall it was just which add-ons to inlcude or not |
| 10:21:38 | wildintellect: | or is that what you mean |
| 10:22:37 | arkygeek: | ? not sure i follow you |
| 10:28:22 | markusN: | wildintellect: I mean gcc optimization |
| 10:28:52 | markusN: | what I guess you mean is that Addons contains *replacements* for some modules |
| 10:29:00 | markusN: | r.los -> r.viewshed |
| 10:29:06 | markusN: | r.cost -> r.terracost |
| 10:29:18 | markusN: | the new implementations are completely different |
| 10:29:27 | markusN: | and 1000 to 1 million times faster : ) |
| 10:29:59 | markusN: | some precision issue yet in r.viewshed otherwise it had been moved to main GRASS already |
| 10:30:12 | markusN: | and r.terracost just arrived and needs more testing |
| 10:30:37 | wildintellect: | markusN, I guess I'm confused by "I don't know if William uses optimization" |
| 10:30:55 | wildintellect: | are there flags to better optimize when running make? |
| 10:30:59 | doktoreas: | hello folks |
| 10:31:49 | markusN: | hi doktoreas |

| 10:33:55 | markusN: | so yes |
| 10:34:28 | markusN: | William doesn't use -O2 optimization to my knowledge |
| 10:34:47 | markusN: | ( btw: -O3 may case troubles ) |

| 11:11:20 | wildintellect: | markusN, ah thanks I wasn't aware of those since there not in the general build docs |
| 11:11:33 | wildintellect: | and I don't really know my way around make |
| 11:17:52 | : | * markusN checks INSTALL file |
| 11:20:21 | wildintellect: | ah I always follow the webpages |
| 11:22:35 | wildintellect: | I see it in the INSTALL file, although there's no explanation of what -O2 does |
| 11:22:41 | wildintellect: | or means |
| 11:22:55 | markusN: | see ( I ) CODE OPTIMIZATION |
| 11:23:09 | markusN: | well, it optimizes : ) |
| 11:23:23 | markusN: | no idea what's behind, I don't know gcc internals |

| 11:26:24 | wildintellect: | markusN, thanks, that's quite informative and I'll have to remember it for all sorts of other stuff |
| 11:28:29 | markusN: | the optimization business is quite complex |

| 11:40:04 | wildintellect: | about the only thing I don't see is the -j option for people with more than 1 core or cpu |
| 11:40:41 | markusN: | good point |
| 11:40:49 | markusN: | but that's make not optimization |
| 11:41:31 | wildintellect: | it optimizes the time to build but yes not technically |

| 11:52:03 | wildintellect: | ah, yes good I should have permission then |

| 16:54:40 | madcat`: | hey |
| 16:57:00 | madcat`: | anyone here? |
| 21:59:50 | arkygeek: | good morning :- ) |
| 22:01:02 | arkygeek: | I have about 200 rasters that are quite large, but they don't need to be... they are binary, with only a bit in the center as 1's. The zeros are irrelevant to me. Is there a way I can reduce the size of the raster? |
| 22:02:42 | arkygeek: | I generated them from a cost surface created by r.walk that goes from 0 to 100,000 and then stopped at a certain extent and kept all points within that extent that were less than a certain slope |
| 22:16:38 | cgs_bob_: | arkygeek: hi there! you might be looking for r.compress? |
| 22:17:15 | arkygeek: | cgs_bob_: i will read the man page about that |
| 22:18:36 | cgs_bob_: | arkygeek: from what I read, you have to uncompress the fil before you use it. |
| 22:19:03 | arkygeek: | GRASS programs can read both compressed and regular ( uncompressed ) file formats. This allows the use of whichever raster data format consumes less space. |
| 22:19:20 | arkygeek: | but it looks like they should be compressed aoutomatically |
| 22:20:16 | cgs_bob_: | you would think : ) I'm sure it is not done because it would affect performance |
| 22:20:24 | arkygeek: | cgs_bob_: I think i need to somehow acutally remove the zero values |
| 22:20:31 | arkygeek: | 'trim' the raster |
| 22:22:39 | cgs_bob_: | I wonder if you can use gdal and create a 1 bit tif with 0's as nodata? |
| 22:23:05 | arkygeek: | does it make it smaller if I replace all the zeros with nullData? |
| 22:23:12 | arkygeek: | r.null will do that if it does |
| 22:23:57 | cgs_bob_: | I would think so...I guess you'll just have to try |
