This program provides an implementation for four integrators. 

The one that I studied is the Wisdom-Hollman simplectic integrator, which function coresponds to the HWHStep.

Files:

NBIserial.c - serial version of the program.
NBIparalel.c - paralel version of the program.
NBIsampleinput - input file
NBIsampleoutput - output file
NBIsampleoutput.log - log file
scr_serial.sh - script to run the serial version on fep
scr_paralel.sh - script to run the paralel version on fep, it takes as input arguments the number of threads and 	the schedule type

Ex: scr_paralel.sh 4 "guided"

Compile: make
Run: 
	Serial	
	time ./NBIserial NBIsampleinput

Time:
real	0m0.017s
user	0m0.000s

     	Paralel
	setenv OMP_NUM_THREADS 4
	setenv OMP_SCHEDULE "dynamic"
	time ./NBIparalel NBIsampleinput

Time:
