Installing SGE and getting CFX to work with it

shreyasr · August 30, 2012, 03:31

Hi !

My goal is to setup an existing system such that parallel/serial ANSYS CFD (CFX) & Structural simulations submitted to the server are automatically queued. I want to setup the Sun Grid Engine (SGE) to do this. There are currently 2 quad core servers, with 16 GB of RAM each, available, running Red Hat V 5. Other user workstations run Windows 7. These workstations, pull the appropriate ANSYS license files from the server.

Eventually, the idea is to hook up other computers to the servers and utilise idle computing resources for parallel simulations as well.

I've successfully setup PuTTY and the SSH method to access the terminal on the server remotely. I've also written a BASH script to make a single multi core job submission pretty easy.

The next step is to work on the queuing. The plan is to inititally get one server up with the queuing system and then add nodes.

However, I encounter the following error during the installation of SGE :

./utilbin/lx-amd64/uidgid: error while loading shared libraries: libhwloc.so.4: cannot open shared object file: No such file or directory
./utilbin/lx-amd64/gethostname: error while loading shared libraries: libhwloc.so.4: cannot open shared object file: No such file or directory

I get the above error in both the GUI and Command line based installations. I also get the same error when I tried the installation on Ubuntu 10.04 LTS.

Some forums mentioned that the hwloc libraries are not a default part of earlier Red hat distro's. I have also tried installing the hwloc RPM's separately. - I get the same error.

Would deeply appreciate your help and advice in solving the above error as well as going about !

I would be happy to hear suggestions on the implementation, like open source alternatives to SGE as well. I have done some background reading, and for somee reason, felt SGE was easier to handle.

Thanks for your help !

Code:

yum install hwloc-1.1-0.1.el6.x86_64

will get you the needed library providing you have the appropriate repos. I managed to find it on CentOS 6.2 Base, and there should be a similar Fedora Repo. If you can't get the .so.4 file, just create a link to .so.1 called .so.4

Good Luck
