Hi, I have a question about exporting graphics. I usually use the hpc on our university to do calculations, and the workflow is like this: first I request an interaction job on the hpc, and then I lunch a kernel on the interactive node I get, and connect to my frontend on my local computer.
This works great except sometime it give me problem when I need to generate a move or many graphics. I learned that the graphics are always rendered at the frontend, which slows down a lot of the generating of graphics or movie, since my local laptop is quiet slow.
Is there a way to export the movie or graphics without invoking my slow local frontend?
Is there a way to start a frontend at the hpc, or even many frontend so that I can export the graphics in parallel?
@chris I tried this, but always get the error like "can't open display 0:0"
@chris I guess that also uses the frontend to render the graphics, but just in the background. The problem is that there seem to be no x11 on our hpc so that mathematica can't start a fontend
@halirutan on your recent graph answer if we get a 'branch' with, say, relations r [ g[b] , b[g] ] how can I get (using a generic approach) each sub-branch r[g[b]] and r[b[g]] ? I tried various Maps and Applys
for clarity, an ideal output would be { r[g[b]] , r[b[g]] }
@chris thanks for letting me know, let me double check
@chris I have nothing in my init.m
@chris Also there it also says on that page you linked "the following is for Mathematica < version 6; for higher versions you shouldn't expect graphics to work without a windowing system"
Could someone running version 9.0.1 please confirm this reported problem with my code:
The first time I run this, the tag appears twice: When i = 0 When i = 0 Power::indet: "Indeterminate expression 0^0 encountered." — cyberSingularity42 mins ago
@Rojo I suppose not. Still, it's a bit strange, and you were the one to fix an earlier version-related bug in it. Nevertheless I understand that there are more interesting things to work on!
@Rojo Well nuts, I thought I ported your fix but I guess I never did. I am sorry. Would you please try to fix the current version, assuming it is not difficult?
