 Hi Ralph, I changed the intel icc module from 12.1.0 to 11.1.069, the
previous default one used at a Neolith Cluster. I submitted the job and I
still waiting for the result. Here is the message of the segmentation fault:

when I run my application, sometimes I get this error and sometimes it is
stuck in the middle.
