Dear colleagues,


We've newly installed Relion 2 on our work station with 128GB RAM and 2x GTX1080 graphic cards.

During 3-D refine with "3-MPI processes, preload particles in RAM and combined processes through the disk", we got errors as below and it always terminate at iteration 11.

Does any one know what this issue is related and how to resolve it?


Kernel_error:invalid argument in /home/sbgrid/Downloads/relion/src/gpu_utils/cuda_ml_optimister.cu at line 289 (error-code 11)

---------------

mpirun noticed that process rank 1 with PID 16702 no node primo exited on signal 11 (Segmentation fault).

---------------

[primo:16702] [6]/lib64/libc.so.6(__libc_start_main+0xf5)[0x7f49a9e7db35]

[primo:16702] [7]/usr/local/bin/relion/bin/relion_refine_mpi[0x40a2bf]

[primo:16702] ***End of error message***


Thank you very much!


Fei Guo
