Question MPI error message and other applicatioins
1st,I'm a newbie.

I've written a mpi program to realize the parallel computing and encounter many problems.

1. When the computing scale is small, that means the communication time is short, just needs few minutes, such as 14 minutes or less. The program runs well and finished the jog.

But when the computing scale is bigger, that means need hours of running to finish,probelms come. After about half an hour's running,the program exsit with abnormal,the error message is that:p4_error: interrupt SIGx: 6
but the calculating result in the running time is correct.I don't understand the meaning of this error message. Any one can interpret it to me specifically? And if someone could give me the mpi error message list to chech each message's meaning , I'll appreciate it a lot.

2. I'd like to set one rank as the master rank, and give it higher priority. But I still don't know how to se the priority in unix. Maybe someone could give me a way.

Thank you for all your help.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
