Re: mesa-users] Problem with running Mesa/star codes on Xgrid clusters

[Bill P. <pa...@ki...>]

Hi Tursun,

When you run mesa, it loads a few libraries dynamically (i.e., the libraries are not part of the mesa executable).
That works fine if you are running on the same machine you used to build mesa -- or if you are running on a cluster
where the machine that will be running mesa has access to the same file system.

However, I believe that with Xgrid your program is sent to another mac on the local net to be run.
So for that to work with mesa, the other machine must have the necessary libraries available.
In your case, your job cannot run because it has been sent to a machine that lacks the needed library (libgomp.1.dylib).

Moreover, the problem is not limited to libraries.   Even if you have them, you also need the mesa/data directory to be available
from the machine where you are running.

The simple solution is don't use Xgrid!   

If you really-really-really want to use Xgrid, then you probably need to have mesa installed on any machine you'll use.

Mesa works fine on a mac, and it works fine on clusters of linux boxes.
But Xgrid is a bad choice unless you own all the machines and can install mesa on them all.
