This isn't the kind of tuning you'll want to test but anyway here is an example of a script that will test this limit and more than likely crash your OS:
Code:
#!/bin/ksh
count=$(sysdef -i | grep maxup | nawk '{print $1;exit;}')
print "Launch $count processes (WARNING: this WILL brick your system ...) y/[n] : ? "
read yesNo
if [ "$yesNo" = "y" ]
then
echo starting ...
while [ $count -gt 0 ]
do
/usr/bin/sleep $count &
count=$((count-1))
printf "%06d\r " $count
done
sleep 30
ps -ef|wc -l
else
echo "Cancelled"
fi
I have set the maximum no of file descriptors open in a process to the value 8192 using the following lines
set rlim_fd_max=8192
set rlim_fd_cur=8192
in the /etc/system file.
I rebooted the machine and the command ulimit -n / -Hn both display the limits as 8192. However when I run my... (2 Replies)

SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VectorMaximumMag_U8C(mlib_u8 *max, const mlib_u8 *x, mlib_s32 n);
mlib_status mlib_VectorMaximumMag_S8C(mlib_s8 *max, const mlib_s8 *x, mlib_s32 n);
mlib_status mlib_VectorMaximumMag_S16C(mlib_s16 *max, const mlib_s16 *x, mlib_s32 n);
mlib_status mlib_VectorMaximumMag_S32C(mlib_s32 *max, const mlib_s32 *x, mlib_s32 n);
mlib_status mlib_VectorMaximumMag_F32C(mlib_f32 *max, const mlib_f32 *x, mlib_s32 n);
mlib_status mlib_VectorMaximumMag_D64C(mlib_d64 *max, const mlib_d64 *x, mlib_s32 n);
DESCRIPTION
Each of these functions finds the first element with the maximum magnitude in a complex vector, then puts the real and imaginary parts of
it into max[0] and max[1], respectively.
PARAMETERS
Each of the functions takes the following arguments:
max Pointer to the first element with the maximum magnitude.
x Pointer to the first element of the source vector.
n Number of elements in the source vector.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
