Hello,

As you have noticed i have implemented my Parallel Conjugate gradient 
linear system solver, here it is:


https://sites.google.com/site/aminer68/parallel-implementation-of-conjugate-gradient-linear-system-solver


But as you will notice i am using arrays to implement it ,
but arrays do take too much memory even if the matrix is more
sparse, but i have decided to implement it like that with arrays,
so a matrix of 100000 by 1000000 elements will take around
64 Gbytes of memory, so you have to have a server with 32 Gbytes
of memory or more to be able to solve large industrial problems
with my parallel Parallel Conjugate gradient linear system solver.

To use much less memory i have to use linklists , but linklists
are not parallel freindly with my parallel algorithm, they will
be too CPU expensive , hence too slow, so this why i have decided
to keep using arrays in my parallel algorithm


Thank you,
Amine Moulay Ramdane.
