Description: The parallel direct equation solver now supports both shared memory systems and computer clusters. The solver has a hybrid shared memory/distributed memory architecture and features three running modes depending on the computational environment:

Currently unsymmetric matrices and multiple right-hand side analyses are supported only in shared memory mode. Distributed memory and hybrid modes require the element operations to run in parallel as well (see “Parallel execution in ABAQUS/Standard,” Section 11.9.2 in the ABAQUS Analysis User's Manual, for the limitations that apply).

To run the parallel solver, set the cpus command line parameter to a value greater than one. The optional environment variable mp_host_list can be used to describe the individual computers of a cluster. The number of computers and the level of parallelization on each computer are selected automatically according to the specifications in the environment file.
