Thank you Moritz,
I installed OsgeoLive virtual box with GRASS to run fuzzy tools also with 
Linux, so I'll run r.fuzzy.logic there and I'll tell you if it works.

[GRASS-user] r.fuzzy.logic problem

2018-05-17 Thread bonatopaola 
Hi all,
I'm new with GRASS GIS and I'm interesting to learn the use of r.fuzzy.* tools. 
I read Jasiewicz paper (A new Grass GIS fuzzy inference system for massive data 
analys) and I run r.fuzzy.system tool without error. Now I'm trying to 
understand the process step by step using r.fuzzy.set and r.fuzzy.logic. I 
produced membership raster with r.fuzzy.set but when I use its outputs to run  
r.fuzzy.logic I have the follow error: ERROR:  
is not of type CELL.
The tool requires two input raster data and both are FCELL. I have no idea 
where can be the error, both input data are from r.fuzzy.set.
I'm running Grass GIS 7.2.1 in Window 10 and I'm using spearfish60_grass7 maps.

Thanks in advance.

Hi,

sure my answer was for everyone to read, I believe I tried to send it
again afterwards..
something must have gone wrong.

What we did about GRASS + HPC was for specific production purposes and
no documentation
whatsoever wascreated, basically due to lack of time.. so I find it
hard to say whether this is going
to change in the near future:). Surely the topic is of wide interest
and worth being discussed in
several contexts.

I must admit that existing documentation/papers did not help much.
Well, did not help at all, actually.
One major problem in my opinion/experience is that
multi-core/multi-node machines can be really
different from each other, and parallelization strategies very
purpose-specific, so that creating
general-purpose documents/papers, or even software, *may* be a
hopeless effort. Smart ideas
are most welcome, of course:)

Hi all,

is there already some kind of up to date list / global map of GRASS 
installation in HPC-cluster environments ?

This would be handy to get a feeling about how much "big geospatial number 
crunching" is currently done with GRASS, and where to visit / whom to talk to to 
learn from others.

Best,
Peter


Ciao Peter, and all,

I *still* need to do my "homework" and transfer "my" notes about GRASS
GIS and HPC in the wiki. I will create a dedicated "HPC" wiki page. I
hope this will be a starting point.

As usual, all this if there are no objections.

See my other mail which I wrote before seeing yours.

Hi Massi,

Hi GRASS HPC users,

we (Massimiliano Alvioli and Ivan Marchesini, at CNR IRPI 
http://www.irpi.cnr.it) spent a significant amonut of time using GRASS 
on local multi-core machines,
remote machines running the PBS jobs scheduler and also HPC machines, 
mainly the former Galileo and Marconi clusters and at CINECA (Italy), 
running the
SLURM job scheduler. We never published anything on the subject, but we 
will be happy to discuss with other interested people.


I just presented GRASS and a short overview over GRASS on HPC yesterday 
at the FOSS4F-FR and there was a lot of interest for this. Several 
people asked me about specific documentation on the subject.


Currently, I'm aware of the following wiki pages which each potentially 
touches on some aspects of HPC:


https://grasswiki.osgeo.org/wiki/Parallel_GRASS_jobs
https://grasswiki.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly
https://grasswiki.osgeo.org/wiki/GRASS_and_Shell
https://grasswiki.osgeo.org/wiki/GRASS_GIS_Performance
https://grasswiki.osgeo.org/wiki/Large_raster_data_processing
https://grasswiki.osgeo.org/wiki/Large_vector_data_processing

Then there are elements in some presentations:

https://fosdem.org/2018/schedule/event/geo_grass/
https://archive.fosdem.org/2015/schedule/event/grass_7/

This does not make it easy for people to find a one-stop place for 
guidance on how to work with GRASS in a cluster environment by 
parallelizing jobs.


So, it would be great to create one "GRASS HPC" wiki page and collect 
and structure all relevant info there.
