If you are installing Lumerical products on a production cluster, get them to give you a FlexLM-based license! Those instructions fail to mention that Lumerical also offers FlexLM-based network licenses. This is a bad idea unless you have a small, single-user cluster.
Fdtd solution install#
Instructions on the Lumerical web site say to install the hardware USB key driver on every compute node.Here are my recommendations for installing Lumerical products on a cluster: There is a simple script called install.sh which checks to make sure the user is root and then tries to install a hardware key driver and an RPM that contains the FDTD software. I downloaded the appropriate TAR file from Lumerical, uncompressed it, and looked at the contents. I never install a third-party RPM as root, because a badly constructed package might over-write a system-critical file that some user is depending on. The application is distributed as an RPM package. I used this method to install FDTD Solutions from Lumerical on the STOKES Linux cluster. One approach is to extract the files from the RPM package and install them manually. You are an administrator on a shared cluster and you can’t risk having a package over-write system-critical files.You don’t have root permissions on a system such as a shared cluster.However, I can think of two common circumstances when you don’t want to let RPM install a package: By deploying FDTD Solutions 7.5 alongside Extra Engines, users can make maximal use of their computing resources to rapidly explore a broad parameter space to identify the best design.Most of the time, RPM (especially in conjunction with yum) is a decent package management solution. Each additional one enables another computer resource to take part in a parameter sweep or optimisation task. Researchers and designers can access the concurrent computing capabilities available in FDTD Solutions 7.5 by obtaining Extra Engines licenses. The time required to find an optimal design can easily be reduced by a factor of ten or more using the computers found in most offices or labs.’ ‘This release completes a multi-year mission to get individual computers simulating as fast as possible, and then to send those simulations to all available computers conveniently from your workstation. ‘FDTD Solutions 7.5 allows end-users to optimally achieve design goals on modern computing hardware,’ said James Pond, Lumerical’s CTO. Together with Lumerical’s capabilities for distributed computation on high-performance computing clusters, FDTD Solutions 7.5 offers speed improvements when used on multiple desktops and workstations within traditional computer networks. Lumerical Solutions has released FDTD Solutions 7.5 which features a concurrent computing capability allowing users to distribute simulations on multiple independent computer resources.
