openmp parallelization working again (at least for j2 and nonlocal constitutive model).
In order to keep it like that, please follow these simple rules:
DON'T use implicit array subscripts:
example: real, dimension(3,3) :: A,B
A(:,2) = B(:,1) <--- DON'T USE
A(1:3,2) = B(1:3,1) <--- BETTER USE
In many cases the use of explicit array subscripts is inevitable for parallelization. Additionally, it is an easy means to prevent memory leaks.
Enclose all write statements with the following:
!$OMP CRITICAL (write2out)
<your write statement>
!$OMP END CRITICAL (write2out)
Whenever you change something in the code and are not sure if it affects parallelization and leads to nonconforming behavior, please ask me and/or Franz to check this.

! HALTON_SEED_SET sets the "seed" for the Halton sequence.
!
! Calling HALTON repeatedly returns the elements of the
! Halton sequence in order, starting with element number 1.
! An internal counter, called SEED, keeps track of the next element
! to return. Each time the routine is called, the SEED-th element
! is computed, and then SEED is incremented by 1.
!
! To restart the Halton sequence, it is only necessary to reset
! SEED to 1. It might also be desirable to reset SEED to some other value.
! This routine allows the user to specify any value of SEED.
!
! The default value of SEED is 1, which restarts the Halton sequence.

! distinct prime numbers. This routine only checks that each base
! is greater than 1.
!
! Input, integer NDIM, the dimension of the sequence.
!
! Output, real R(NDIM), the SEED-th element of the Halton sequence
! for the given bases.

!
! Note:
2011-12-01 17:31:13 +05:30
! PRIME_MAX is 1500, and the largest prime stored is 12553.

! Parameters:
2011-12-01 17:31:13 +05:30
! Input, integer N, the index of the desired prime number.
! N = -1 returns PRIME_MAX, the index of the largest prime available.
! N = 0 is legal, returning PRIME = 1.
! It should generally be true that 0 <= N <= PRIME_MAX.
!
! Output, integer PRIME, the N-th prime. If N is out of range, PRIME
! is returned as 0.
