[mesa-users] Running Speeds of MESA

[Francis Timmes]

also, for a comparison point, you could try running a similar model at http://mesa-web.asu.edu

Decreasing mesh_delta_coeff decreases the spatial resolution (less zones) which should make you use less ram and each step run quicker. You could also try using a smaller nuclear network to make the steps quicker.

At the moment it takes an hour plus to run it for a 1Msun star with Z = 0.001 and after an hour it's only at 6.349e9 years. Is there something I can do to speed up the program or maybe allocate how much ram it uses? At the pace it is going it is almost impractical to use for any research or classwork for my Astronomy class. I have a 2012 Macbook Pro 13 inch, 4gb DDR3 RAM, 2.5 GHz Intel Core i5 cpu, with OSX 10.10.5. I am running MESA-r7624, with  Version 20150908 of the MESA-sdk.
