DISUTIL
Broadcast data blocks between slave and master processors
Parameters:
NSKIP Input-integer-default=1. Record number in CASECC
corresponding to the first subcase of the current boundary
condition.
EPSI Output-integer-default=1. Static solution error ratio flag. Set to -1
if the error ratio is greater than 1.E-3.
DISMETH Input-integer-default=1. Method.
Remarks:
1. All executions of DISUTIL must be synchronized across all processors.
2. EPSSE may be purged. EPSSE contains:
a. Sequential number of subcases
b. Superelement (domain) identification number
c. Epsilon error ratio
1 Compute epsilons and external works assuming a-set
components of RUF are local values (which occurs in a
direct solution)..
2 Compute epsilons and external works assuming a-set
components of RUF are global values (which occurs in a in
iterative solution).
3 Broadcast table or matrix from master to slaves.
4 Broadcast VECPLOT resultant output from slaves to master
and combine on master.
5 Broadcast VECPLOT maxima output from slaves to master
and combine on master.
6 Broadcast displacement matrices from slaves to master and
merge into global displacement matrix on master.
7 Broadcast force matrices from slaves to master and
add/merge into global force matrix on master.
8, -8 Broadcast any matrix from slaves to master and add all
matrices on master. DISMETH=8 is recommend for dense
matrices and -8 for sparse matrices.
9 Broadcast any matrix from slaves to master and append
columnwise all matrices on master.
