Dear Mr/Ms,
I am a dutch student and on this moment I'm following a traineeship at
TNO. TNO has a cluster to compute parallel problems. One of my tasks is
to find out which libraries can be used for parallel computing, for
example solving a system of lineair equations.
I have tried to use the subroutine PSGESV but it still doesn't work. The
problem is that I don't know how exactly work the subroutines DESCINIT
and PSGESV.
Imagine, we have the system of lineair equations Ax=B with:
1 2 3 4 5 6 7 8 9 285
1 2 3 4 5 6 7 8 9 283
1 2 3 4 5 6 7 8 9 277
1 2 3 4 5 6 7 8 9 267
A = 1 2 3 4 5 6 7 8 9 B = 253
1 2 3 4 5 6 7 8 9 235
1 2 3 4 5 6 7 8 9 213
1 2 3 4 5 6 7 8 9 187
1 2 3 4 5 6 7 8 9 157
Processgrid: (1,4)
Blocksize : (2,2)
My question is: what are the values from the arguments from the
subroutines DESCINIT and PSGESV (in Fortran 90)?
On the Internet, I've seen many examples of PSGESV but I still don't
understand how I can solve this system of lineair equations.
I hope so much that you can help me further! Would you please help me?
Kind regards,
Peter Keereweer
