enquiry about running a program on server!

Dear All,

I want to make an enquiry about running program on computer server. I submitted two jobs to the server and, after a while, I use 'jobs' command to check them and the results are shown below:
[1]- Running castep La & (wd: ~/work/Laanatase)
[2]+ Running castep Ce & (wd: ~/work/Ce)

I noticed that there are symbols '-' and '+' after the job numbers. Could anyone tell me what they mean?

I also used 'ps aux' command to check these two jobs and results are shown below:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
kenan 806 292 1.9 966004 642820 pts/2 R1 Mar30 66626:02 castep La
kenan 25929 207 1.7 878616 573780 pts/2 R1 Apr10 14343:11 castep Ce

The 'STAT' of these two jobs are both 'R1'. I know 'R' means the program is running but I do not know what 'R1' means. Could anyone tell that?

I know what the '%CPU', '%MEM', 'vsz' and 'RSS' denote but I do not know what the data denote. For example, '%CPU' and '%MEM' of the first job is 292 and 1.9. Do these values denote the rpogram is running properly or not well? Could anyone tell me what the kind value denote the program is running properly?

Any great help appreciated!

The 'ps' part is already answered in thread http://www.linuxquestions.org/questi...fields-563716/

PROCESS STATE CODES
Here are the different values that the s, stat and state output specifiers
(header "STAT" or "S") will display to describe the state of a process.
D Uninterruptible sleep (usually IO)
R Running or runnable (on run queue)
S Interruptible sleep (waiting for an event to complete)
T Stopped, either by a job control signal or because it is being traced.
W paging (not valid since the 2.6.xx kernel)
X dead (should never be seen)
Z Defunct ("zombie") process, terminated but not reaped by its parent.

For BSD formats and when the stat keyword is used, additional characters may
be displayed:
< high-priority (not nice to other users)
N low-priority (nice to other users)
L has pages locked into memory (for real-time and custom IO)
s is a session leader
l is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
+ is in the foreground process group

I'm not sure if '+' has the same meaning for 'jobs', though it seems possible.

Thank you very much for this information. I know 'R' under 'STAT' column means the program is running or runnable but under the 'STAT' column of my program there is 'R1' symbol and I do not know what 'R1' symbol means. Would you please tell me the meanning of 'R1' symbol? I really appreciate your help!
