Why my running be killed?

[cdd]

Hi,

When i run gyre-tasc5 with command "gyre_force test.in(

test.in

(620 Bytes) Downloaded 327 times

)", the os always kill my program. I use command "dmesg | grep -E -i -B100 'killed process" to check the killed process, it give me below message:

It seems that gyre_force run out of memory. I attached the files i use in the running, and hope anyone can give me any suggestion. Thank you for any help in advance.

Hi Chen --

Looking at the output you posted, it seems you are looking for modes in a dimensionless frequency interval 0.4845E-06 -> 0.1454E-05. These very low frequencies correspond to very high-order g modes. In order to resolve the spatial oscillations of these modes, GYRE attempts to create a very fine spatial grid. Unfortunately, your computer does not have enough memory to hold this grid, hence the program crashes.

cheers,

Rich

Hi Rich,

I run this with dimesionless frequency range and can get needed frequency successfully. So thank you for your reply and help very much!

Best Wishes

For what it's worth, I'm also running into memory issues from remeshing the grid even for computing radial p-modes (so no g-mode mixing expected). I can confirm that increasing the minimum frequency of the search interval relieves the memory pressure (I use Δν/10 as the lower bound of the interval, which has been working fairly decently).
