@brucefan1983 I have just found out that this problem occurs even though I am running the simulation on a node with a single GPU. I will change the title and description accordingly.

Here are the input files:
test_vel100_nvt_lan_T100_Tc200_dump1000_run100000.tar.gz
As well as the potential:
ols_original_model_1_2x2x2_orders_2-3_tol1e-08.tar.gz
from gpumd.
Thanks for your inputs. I have solved the problem. It is bug in the code related to the neighbor list construction/update. Some arrays only have a length of N
(number of atoms), but when the cutoff distance is 0.1 Angstrom (I recommended this to you, sorry), the number of bins exceeds N
, which results in some invalid memory access. For the time being, I have disabled neighbor list construction/update for the FCP potential (need -DUSE_FCP
in the makefile
), becasue we don't need the neighbor list at all for this potential.
For your inputs, I would like to mention that, to use NetCDF
, you need to build it according to the manual:
https://gpumd.zheyongfan.org/index.php/NetCDF_setup
https://gpumd.zheyongfan.org/index.php/The_dump_position_keyword
Without the compute command, your inputs run correctly in my laptop now.

Sorry, I have a typo,
Without the compute command
should be
Without the dump_position command
from gpumd.
Thank for the taking care of this so quickly @brucefan1983. I have now been able to run all the calculations without any issues.
By the way, I have already installed netcdf according to the instructions that you refer to. It would, however, be great if GPUMD could have support for other, especially more recent, versions of netcdf. Is this something that you are working on?
I suppose it should be possible to close this issue, right?

Since this bug was fixed I close this issue now.
