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

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

why is this still in run level 3?

cachefsstat
cachefsstat(1M) System Administration Commands cachefsstat(1M)NAME
cachefsstat - Cache File System statistics
SYNOPSIS
/usr/bin/cachefsstat [-z] [path...]
DESCRIPTION
The cachefsstat command displays statistical information about the cache file system mounted on path. The statistical information includes
cache hits and misses, consistency checking, and modification operations. If path is not specified, all mounted cache file systems are
used.
cachefsstat can also be used to reinitialize this information (see -z option).
The statistical information has the following format:
<cache hit rate>
<consistency checks>
<modifies>
where:
hit rate The percentage of cache hits over the total number of attempts, followed by the actual numbers of hits and misses.
consistency checks The number of consistency checks performed, followed by the number that passed, and the number that failed.
modifies The number of modify operations, including writes, creates, etc.
OPTIONS
The following option is supported:
-z Zero (reinitialize) statistics. Execute cachefsstat -z before executing cachefsstat again to gather statistics on the cache per-
formance. This option can only be use by the superuser. The statistics printed reflect those just before the statistics are
reinitialized.
USAGE
See largefile(5) for the description of the behavior of cachefsstat when encountering files greater than or equal to 2 Gbyte (2**31 bytes).
EXAMPLES
Example 1: Using cachefsstat
The following example shows the cachefsstat command run on file system /test:
example# cachefsstat /test
/test
cache hit rate: 100% (0 hits, 0 misses)
consistency checks: 0 (0 pass, 0 fail)
modifies: 0
garbage collection: 0
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
