I have a problem with OSX and I know that some of you are used to it. I can run a Navier-Stokes DG P2 code in parallel with more than two processes but in serial I get the following error
ns-opt(2096) malloc: *** mmap(size=1644146688) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug [0]PETSC ERROR: --------------------- Error Message ------------------------------------ [0]PETSC ERROR: Out of memory.

If I try to run a P3 in parallel (4 processes is the max for my mac) I get the same error. With ulimit i get core file size (blocks, -c) 0 data seg size (kbytes, -d) 6144 file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited It seems that there isn't a process memory limit. Any idea? Thanks for help!
