Dear all,
I am trying to run a simulation on HPC.I have defined a region,beyond “10 Angstorm” it is showing following error DESCRIBED below .My region defined is
region whole block 0 20.0 -80.0 80.0 -80.0 80.0 as it is written 20 in x-axis,
But running beyond 10 it always shows the error described below.
As running it on multiple processors(nodes=5;ppn=20) shows the error.
But when we run the same program on a single processor then there is no error.The program only runs on single processor.Can anybody tell me how to debug this problem.
With Regards,
Ritesh Satwani
