OSMesa

[Emily Lane]

Kia ora koutou,

I was compiling a basilisk file on the NZ REANNZ HPC (previously NeSI) and got an error message about OSMesa for a code that had previously worked. Talking with the support folks it turns out that Mesa is stopping support for the off screen rendering. At the moment I can get around this because some of the login nodes have older versions which still have OSMesa but these may also be removed in the future.

I am really just flagging this at this stage and wondering whether there are plans to look at alternatives for visualisation?

Cheers

Emily

Hi Emily,

I am not sure which version of Basilisk you are using, but it has been
years since Basilisk relied on OSMesa for rendering... More or less
since this patch:

* A tiny implementation replaces OpenGL/OSMesa

cheers,
