Does anyone have experience in deploying the WIndows HPC private cluster, or executing an Abaqus job on two computers without queuing server using MPI Parallelisation?
I have managed to set-up the Cluster and to join the headnode running on Windows Server 2012 R2 and one compute node "W510" running on Windows 7 64bit Ultimate.
Unfortunately I keep getting the following error massage:
Failed to execute "hostname" on host "w510". Please verify that you can execute commands remotely on "w510" without a password. Command used: "C:\Program Files\Microsoft MPI\Bin\mpiexec.exe -wdir C:\Windows -hosts 1 w510 1 -env PATH C:\SIMULIA\Abaqus\6.13-4\code\bin;C:\Windows\system32 C:\SIMULIA\Abaqus\6.13-4\code\bin\dmpCT_rsh.exe hostname".
I am not able to go into your Particular Set up. However I think that the following References may be helpful
1. Sparse Matrix Structure for Dynamic Parallelisation Efficiency

The simulated models and requirements of engineering programs like computational fluids dynamics and structural mechanics grow more rapidly than single processor performance. Automatic parallelisation seem to be the obvious approach for huge and historic packages like PERMAS. The approach is based on dynamic scheduling, which is more flexible than domain decomposition, is totally transparent to the end-user and shows good speedups because it is able to extract parallelism where others are not. In this paper we show the need of some preparatory steps on the big input matrices for good performance. We present a new approach for blocking that saves storage and decreases the computation critical path. Also a data distribution step is proposed that drives the dynamic scheduler decisions such that an efficient parallelisation can be achieved even on slow multiprocessor networks. A final and important step is the interleaving of the array blocks that are distributed to different processors. This step is essential to expose the parallelism to the scheduler.

Analyses using the direct sparse solver and any of the procedures above that support only MPI-based parallelization of element operations can be run on computer clusters.
For analysis using the direct sparse solver and not containing parallel cavity decomposition, thread-based parallelization of the element operations is used on shared memory computers and a hybrid MPI and thread parallel scheme is used on computer clusters. For analyses using the iterative solver or if parallel cavity decomposition is enabled, only MPI-based parallelization of element operations is supported.

P.S.
if you installed documentation of abaqus then :
http://127.0.0.1:2080/v6.14/books/usb/default.htm?startat=pt01ch03s05aus33.html
the version of documentation that you installed should be replaced in link. i have 6.14 so you can change it by your own.
