Hi<br>
<br>
I am working with the r.mapcalc graph function. When the input
(number of xy pairs) is very high, I am getting an error message:<br>
<br>
"memory exhausted<br>
Parse error<br>
ERROR: parse error"<br>
<br>
The largest possible number of xy pairs seems to be somewhere
between 2400 and 2500. It runs with 2400 xy pairs, and pretty fast
for that matter. Memory usage doesn't go beyond 1.5GB with 2400 xy
pairs, while I have 12GB RAM (on 64bit Linux computer), so I guess
RAM isn't the limitation here.<br>
<br>
In the help page of r.series, there is a mention of a soft limit of
1024 files. Does something similar apply here (but with different
numbers)?<br>
<br>
I can actually work around it, using a approximation of the graph
function, but would like to know at what number of xy pairs I should
apply the workaround. Particularly important, is the limit the same
for all users, or if not, what would be a safe limit? Or is there a
way to set this limit from within a script?<br>
<br>
Cheers,<br>
<br>
Paulo<br>
