Hello everybody.
I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.
I had the same problem with another AIX 5.3 running the same... (2 Replies)
Hi folks,
I'm running RHEL4 (2.6.9 - 64 bit) on a 4 CPU Dual Core Xeon. This server is running DB2 database. I've been getting the following readings from sar over the past week:

I am interested in setting up some High Performance Computing clusters and would like to get people's views and experiences on this.
I have 2 requirements:
1. Compute clusters to do fast cpu intensive computations
2. Storage clusters of parallel and extendable filesystems spread across many... (6 Replies)
Sorry, I am not really from a computer science background. But from the subject of it, does it mean something like multi processor programming? distributed computing? like using erlang? Sound like it, which excite me. I just had a 3 day crash course in erlang and "Cocurrency oriented programming"... (7 Replies)
hello everyone ,
Im new to HPL. i wanted to know whether High performance linpack solves linear
system of equations for single precision airthmatic on LINUX.
it works for double precision , so is there any HPL version which is for single precision.\
thanks . (0 Replies)
I'm trying to compile Linpack on a Ubuntu cluster. I'm running MPI. I've modified the following values to fit my system TOPdir MPdir LAlib CC LINKER.
When compiling I get the following error: (the error is at the end, the other errors in between are because I've ran the script several times so... (0 Replies)

pset_getloadavg
pset_getloadavg(3C) Standard C Library Functions pset_getloadavg(3C)NAME
pset_getloadavg - get system load averages for a processor set
SYNOPSIS
#include <sys/pset.h>
#include <sys/loadavg.h>
int pset_getloadavg(psetid_t pset, double loadavg[], int nelem);
DESCRIPTION
The pset_getloadavg() function returns the number of processes assigned to the specified processor set that are in the system run queue,
averaged over various periods of time. Up to nelem samples are retrieved and assigned to successive elements of loadavg[]. The system
imposes a maximum of 3 samples, representing averages over the last 1, 5, and 15 minutes, respectively.
The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be used to extract the data from the appropri-
ate element of the loadavg[] array.
If pset is PS_NONE, the load average for processes not assigned to a processor set is returned.
If pset is PS_MYID, the load average for the processor set to which the caller is bound is returned. If the caller is not bound to a pro-
cessor set, the result is the same as if PS_NONE was specified.
RETURN VALUES
Upon successful completion, the number of samples actually retrieved is returned. If the load average was unobtainable or the processor
set does not exist, -1 is returned and errno is set to indicate the error.
ERRORS
The pset_getloadavg() function will fail if:
EINVAL The number of elements specified is less than 0, or an invalid processor set ID was specified.
The caller is in a non-global zone, the pools facility is active, and the specified processor set is not that of the zone's
pool.
