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,

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?

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:

pthread_detach
PTHREAD_DETACH(3) BSD Library Functions Manual PTHREAD_DETACH(3)NAME
pthread_detach -- detach a thread
SYNOPSIS
#include <pthread.h>
int
pthread_detach(pthread_t thread);
DESCRIPTION
The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when the thread
terminates. If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on
the same target thread is unspecified.
RETURN VALUES
If successful, the pthread_detach() function will return zero. Otherwise an error number will be returned to indicate the error. Note that
the function does not change the value of errno as it did for some drafts of the standard. These early drafts also passed a pointer to
pthread_t as the argument. Beware!
ERRORS
The pthread_detach() function will fail if:
[EINVAL] The implementation has detected that the value specified by thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to that specified by the given thread ID, thread.
SEE ALSO pthread_join(3)STANDARDS
The pthread_detach() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
