00:28:39 arkygeek: hey _wolf_ ... is GRASS a lot slower on osx than on linux?
00:29:00 arkygeek: or
00:29:21 arkygeek: can going from 3 gb ram to 2 gb ram make things like r.walk take 10x as long?
00:39:49 : <_wolf_> arkygeek: I think it should be about the same
00:40:09 : <_wolf_> maybe linux has better disk buffer handling?
00:40:33 : <_wolf_> how large is the raster map?
00:40:36 arkygeek: it must. my runs are taking 20 mins in osx. linux they were taking 2
00:40:56 : <_wolf_> hmmh that is quite odd
00:41:13 arkygeek: i think i had better check a few other things out.
00:41:14 : <_wolf_> maybe the mac is swapping you sooner than linux is?
00:46:33 arkygeek: i wonder if there is a way to make r.walk set it's limit to be whatever it is when it gets to the edge of the dem
00:57:25 : <_wolf_> you could maybe restrict your region to something smaller?
01:06:27 epifanio: i'm using both osx and linux ... there isn't so large difference beetween the 2 platform ... yes linux is fast than osx but just a bit .. maybe beacouse it has full 64bit support
01:11:25 arkygeek: epifanio: funny though... i didn't install the 64bit linux on it though
01:12:04 arkygeek: I am going to go get some more ram and see if that makes a diffrence
01:12:34 arkygeek: maybe i should try to sort out my grass issues in linux and just run my app in linux...
01:12:54 epifanio: humm that so strange a so larger gap-time! .. have you tried exactly the same command on the same mapset , extent and resolution ?
01:13:34 arkygeek: epifanio: i have to fix grass in linux b4 i can test it again
01:13:58 arkygeek: let me restart into linux and chat with you there.... give me a minute
01:14:09 : * arkygeek goes to shut stuff down and reboot
01:14:17 epifanio: ok
05:38:42 arkygeek: hi again :- )
05:39:14 arkygeek: so, I have my stuff running in linux, and it is taking about 2 minutes to complete,... in osx, ( same computer ) it is taking 20+ minutes
05:39:51 arkygeek: if anyone has any ideas.....
06:11:27 : * arkygeek reboots to add more ram.... :-D
06:43:23 arkygeek: hi again
06:43:32 arkygeek: so, i added ram ( now at 3 gb )
06:44:15 arkygeek: the identical processes in linux took 2 minutes ( with 2 gb ram ) and in osx they take 9
06:44:30 arkygeek: how/why can this be?
06:56:33 arkygeek: correction... make that 20+ minutes
06:56:50 arkygeek: there has to be badness happening here somewhere
07:01:12 CIA-9: mmetz * r36547 /grass/trunk/lib/vector/Vlib/snap.c: Snap lines: use closest anchor, not first best, lighter on memory and a bit faster
09:02:10 madi: hi all
09:03:10 madi: trying to use the command s.surf.rst on grass 6.5 it answers s.surf.rst: command not found
09:04:00 madi: please can anybody say me where can i download this module
