Inconsistency with parallel run
Hi All,

I am running a parallel processing on aggregating a file. I am splitting the process into 7 separate parallel process and processing the same input file and the process will do the same for each 7 run. The issue I am having is for some reason the 1st parallel processes complete first with minimum time and the second complete as second and so on. Each process completion having significant difference in time.

I tried to look CPU usage when process with top command all the process is occupying 97% of CPU not sure why there is a difference between each parallel run.

Is there a way I can trace the process and find whether it is problem with IO/ Memory or CPU.

Note: Each process will read the same file from NAS mount and do the aggregation. I am using RedHAT

Thanks
Arun
