<div class="moz-cite-prefix">Hi Max,<br>
<br>
the settings in config.properties is obviously only for the
creation of the graph. As on Android you only have 32MB ...<br>
<br>
If you look in the Android code you see the call
graphhopper.forMobile() which calls setMemoryMapped() which is
equivalent to MMAP_STORE in the config.properties<br>
<br>
BTW: MMAP_STORE_SYNC is a bit slower and only necessary if you
want to use the MMAP option for the server to guarantee
read-thread safety<br>
<br>
<div>> Maybe I need to increase memory JVM with<b> <i>-Xmx..</i>.
</b>option for pass the lack of memory heap at graph generation
step ?</div>
<br>
If you increase it it should work. e.g. via <br>
<pre>export JAVA_OPTS="-Xmx..."; ./graphhopper.sh ...</pre>
<br>

Peter.<br>

<div dir="ltr">Hello,
<div><br>
</div>
<div>I tested the new version 0.2 on my Android device.</div>
<div>So I was forced to generate new graph because of the new
version of node (V2)</div>
<div><br>
</div>
<div>I want to understand the difference between the two
following option in config file:</div>
<div>
<div><br>
</div>
<div><b><i># graph.dataaccess=MMAP_STORE_SYNC</i></b></div>
<div><b><i>graph.dataaccess=RAM_STORE</i></b></div>
</div>
<div><br>
</div>
<div>I tested to generate <i>France</i> graph (which is big)
with <b><i>graph.dataaccess=RAM_STORE</i></b> but the process
stoped because of lack of memory heap...</div>
<div><br>
</div>
<div>So i change this property to <b><i>graph.dataaccess=MMAP_STORE_SYNC</i></b>
and the process finished correctly and the graph works and my
Android device. The time for generate was approximatly
50minutes (I7 dual core and SSD) for information.</div>
<div><br>
</div>
<div>So I want to know if this option only impact graph
generation and not impact runtime execution?</div>
<div>If there is runtime impact (speed or something else) can I
use <i style="font-weight:bold">graph.dataaccess=RAM_STORE </i>for
android with big graph like the one for France?</div>
<div><i style="font-weight:bold"><br>
</i></div>
<div>Maybe I need to increase memory JVM with<b> <i>-Xmx..</i>.
</b>option for pass the lack of memory heap at graph
generation step ?</div>
<div><br>
</div>
<div>Otherwise good Job, GPS exact routing is perffect :)</div>
<div>Waiting for perfect thing with turn restriction ;)</div>
<div><br>
</div>
<div>Regards.</div>
