We're generating some really cool visualizations, but (as expected) we are running out of memory frequently. We've tried the mod listed at https://gephi.org/users/install/#memory but it seems to be a bit intermittent in that it works on some machines and not others. Here's what we've tried so far:
- Make sure all the machines are on the same OS (In this case, Win 7x64).
Make sure all the machines are on the same version of Gephi (v0.8.2).
Make sure all the machines are on the same JRE (in this case, we downloaded jre-7u21-windows-x64.exe from Oracle).
Explicitly set the path to the JRE using the jdkhome parameter.
Make sure all the machines can start Gephi before we begin twiddling the parameters in the gephi.conf file.
Make the same modifications to memory size on all machines (In this case, -J-Xms64m -J-Xmx10240m).
Some of the machines work great, others throw the dreaded "JRE creation failed" error on the last step. We have 24GB of RAM on the machines in question, so the 10240m allocation *should* go...and does, but not always.
Do we need to be running Gephi64.exe to take advantage of the larger heap allocation? We've tried switching between Gephi.exe and Gephi64.exe. When a machine works with the modified memory parameters, both executables work. When a machine doesn't work, it doesn't matter which executable we try to start.
Totally stumped on this one, and my head hurts from banging it on the desk!
