Something wrong with some of these workunits.
Even though there are some successful in this batch, all 3 that I've received failed immediately (on all hosts these have been) with the following error:

# The simulation has become unstable. Terminating to avoid lock-up (1)
# Attempting restart (step 5000)

One of them had this error also:

SWAN : FATAL : Cuda driver error 700 in file 'swanlibnv2.cpp' in line 1965.

The following workunit progressed very slowly, so I've restarted the host (probably the previous error downclocked the GPU, but I didn't checked it.)

I had one of these fail as well, and it also failed on the other hosts.
