I have collected data of Number of L2 cache misses using PAPI. I had run an MPI application with 4 threads (mpirun -np 4) and each thread reads the cache misses in L2. Each thread outputs data for every timestamp. eg:
Now my qstn , is whether i shud add all the cache miss values at time stamp xxx530 for thread 0,1, 2 and 3 OR shud i take the max-value for thrreda0,1,2,3 for timestamp xxx530 ?
Hi guys,
I have no idea on unix but suddenly, my cobol programs calls a unix script that i know nothing about.
can you guys interpret these lines for me?
i know its a print command but I want to actually know how many copies it prints.
qprt -da -P $1 -t '6' -i '6' -l '70' $2
qprt -da... (1 Reply)
Hi All,
Does anyone familiar with “Rexx interpret” know of a script equivalent?
For those that don't know “Rexx interpret”, here's how a script might look.
variable='echo Hello World!'
interpret $variable
Output is Hello World! because $variable was interpreted.
Thanks,

Hi,
So I am new to Unix, and I need to check the performance of some apps I am running. But I don't know how to interpret the output from TOP.
Could somebody please explain the difference between the different values. And also explain how I can have a process which has a %CPU > 100?

hi
I have a text file abc.txt as below
a = 0
b = 1
c = 3
i want to interpret this file i.e. if number corresponding to 'a' is 0 i want to run a script script.bash .
How do do that? (4 Replies)
Was wondering if someone could interpret this for me -- I'm not sure what everything means. It's a shell script from my bash book:
cd ()
{
builtin cd "$@"
es=$?
echo "$OLDPWD ->$PWD"
return $es
}
what I don't quite understand is the "$@". I think, if I understand... (6 Replies)
I know $0 is the entire file's contents (at least I think that is what it is!), but what exactly is: $0!~
This was a snippet from a larger line
awk '$0!~/^$/ {print $0}'
This deletes blank lines, but I want to know specifically the $0!~ part... I am guessing /^$/ is regex for blank line...... (5 Replies)
Can anyone tell me how to interpret this:
listpage="ls |more" (the spaces are there in the example)
$listpage
It's from my bash book and I'm not sure what it means (3 Replies)
hi All,
i have never used sed in Unix environment, but i have one script which is using this following command:
cat audit_session_rpt_MSP_20140331.lst|sed -n '/Apr 14/!p'| sed -n '/Page/!p'| sed -n '/UserName/!p' |\
egrep -v '^-|^=|^\*'|sed '/^$/d'|sed -e '1,7d'... (1 Reply)
I booted into single user mode with
/usr/sbin/reboot -- -s
but after doing a control -d
my

I was expecting it to show run-level S
why is this still in run level 3?

thread
thread(9s)thread(9s)NAME
thread - General: Contains kernel threads-related information
SYNOPSIS ----------------------------
Member Name Data Type
----------------------------
wait_result kern_return_t
----------------------------
MEMBERS
Specifies the outcome of the wait. The kernel can set this member to one of the following values: THREAD_AWAKENED, THREAD_INTERRUPTED,
THREAD_TIMED_OUT, THREAD_SHOULD_TERMINATE, and THREAD_RESTART.
DESCRIPTION
The thread data structure contains kernel threads-related information. Kernel modules typically use the wait_result member (with the cur-
rent_thread routine) to check for the result of the wait. The values associated with the wait_result member have the following meanings:
The result of the assert wait is a normal wakeup. The wait condition was interrupted by the clear_wait routine. The specified timeout has
expired. The result of the assert wait is that the current kernel thread should terminate. The current kernel thread should be restarted.
NOTES
The header file <thread.h> shows a typedef statement that assigns the alternate name thread_t for a pointer to the thread data structure.
Many of the kernel threads-related routines operate on these pointers to thread data structures.
The thread data structure is an opaque data structure; that is, all of its associated members (except for the wait_result member) are ref-
erenced and manipulated by the operating system and not by the user of kernel threads.
