check the C colmun of the ps output over several iterations and if the number is consitantly high(determined by what you think is high) then take action. you might also be able to run nmon in batch mode.

I am running a Dell PE R815 with 4 x AMD 12 core CPUs with 128GB of RAM and a RAID 5 array of 6 SAS disks. This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...

mlib_status mlib_SignalLimit_F32S(mlib_f32 *srcdst, const mlib_f32 *low, const mlib_f32 *high, mlib_s32 n);
DESCRIPTION
Each of these functions performs hard limiting.
For monaural signals, the following equation is used:
dst[i] = low[0] if src[i] < low[0]
dst[i] = src[i] if low[0] <= src[i] < high[0]
dst[i] = high[0] if src[i] >= high[0]
where i = 0, 1, ..., (n - 1).
For stereo signals, the following equation is used:
dst[2*i] = low[0] if src[2*i] < low[0]
dst[2*i] = src[2*i] if low[0] <= src[2*i] < high[0]
dst[2*i] = high[0] if src[2*i] >= high[0]
dst[2*i+1] = low[1] if src[2*i+1] < low[1]
dst[2*i+1] = src[2*i+1] if low[1] <= src[2*i+1] < high[1]
dst[2*i+1] = high[1] if src[2*i+1] >= high[1]
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes some of the following arguments:
dst Destination signal array.
src Source signal array.
srcdst Source and destination signal array.
low Lower input limit. In the stereo version, low[0] contains the lower limit for channel 0, and low[1] contains the lower
limit for channel 1.
high Upper input limit. In the stereo version. high[0] contains the upper limit for channel 0, and high[1] contains the upper
limit for channel 1.
n Number of samples in the source signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
