[SCore-users-jp] [SCore-users] Problem with SCASH OMP program - efficiency ...!!!

[M.Ramesh]

hi...

(/opt/omni/lib/openmp/examples/scash-test/laplace-f77)

Here when i run the lapalace-f77 omp program on 2 dual processor linux
systems , i get the result as follows :


*********************************************
[root ＠ cosmos home]# scrun -nodes=1x2 ./lapsm
SCore-D 5.4.0 connected.
<0:0> SCORE: 2 nodes (1x2) ready.
 sum=  52.1801176
 time=  10.432076
 end..
[root ＠ cosmos home]# scrun -nodes=2x2 ./lapsm
SCore-D 5.4.0 connected.
<0:0> SCORE: 4 nodes (2x2) ready.
 sum=  52.1801176
 time=  10.829392
 end..
[root ＠ cosmos home]# 
*********************************************

And every time it varies...!!! why is that ? 

Is there any reason y im getting more time if i use more nodes...???

Is there any way to make it as faster as usually expected result ? 
pls reply me ...!!!
regards from 
Ramesh --
