[Nek5000-users] Increase nek5000 problem size

[nek5000-users at lists.mcs.anl.gov]

Hi,


I'm new to use nek5000, I have a problem about checkpoint file size. I did test for eddy and set like 1x1=12, 1xd=18, lelt=3000, checkpoint file size is 0.7 MB, it seems very small, If I continue increase memory size, I cannot compile nek5000 correctly, I will get an error like bellow:


obj/bdry.o: In function `trstax_':
bdry.f:(.text+0x10f6): relocation truncated to fit: R_X86_64_32S against symbol `ctmp0_' defined in COMMON section in obj/navier5.o

coef.f:(.text+0x6ef): additional relocation overflows omitted from the output


I already set

# enable BIG MEMORY suuport
BIGMEM="true"

So, if there any other way to to increase problem size? Thanks.

Best,
Kai
