AW: NAMD_2.9_Linux-x86_64-multicore-CUDA Segfaults

Segfaults usually indicate either or programming error or incompatible binaries or libraries. Therefore please give us the output of:

 

“ldd /your/namd/path/namd2”

 

Because I think you might use the wrong “libcudart.so”.

Hi,

I occasianlly run into Segmentation fault in my simulations but recently they become more often. I use NAMD2.9 which I downloaded from NAMD site as binary.

It manifests on two of my machines so far, hence I don't expect any troubles with hardware. Both machines are running Debian wheezy, but with different GPU card. I have tried several versions of nvidia drivers.

The simulation usually runs for 10 to 25 hours before it crashes.

Are there any actions I should take in order to debug the segfault?

Regards

Vlastik
