There are a variety of reasons you may want to run Gauss. View and Gaussian on different computers. The typical reason is that the computer with Gaussian has more resources memory, disks or processors.

Throughout the rest of this document, Ill refer to the machine running Gauss. View if its a Unix computer or Gauss. View. W if its running Windows as the local machine, and the Unix machine on which Gaussian will run as the remote machine. Also, Ill use Gauss. View as short had to mean Gauss. View on a Unix machine, or Gauss. View. W on a Windows machine. The Shortcut. For those who dont want to read the entire document, Ill give a sneak peek at the essential point here the rest of the document will be a description of how to create formatted checkpoint files and how to use them. Gauss. View gets results from Gaussian via formatted checkpoint files and log files i. Gaussian output files. If you already know how to generate formatted checkpoint files and move them around, then you neednt read further. If you didnt understand all that, dont worry, Ill explain it below. Overview. The whole process of creating jobs, running them, and visualizing the results can be broken down into five essential steps Create the input file. Transfer the input file to the remote computer. Run the calculation and prepare the output file. Transfer the output files back to the local computer. View the results. The next few sections describe these steps in detail. First, though, Ill give a brief list of some assumptions Ive made about how things computers and software are set up. Ill assume the local machine has the following Gauss. View is installed if it is a Unix machine Gauss. View. W is installed if it is running Windows. Either Gaussian or the Gaussian utilities are installed. Technically, it is possible to generate cube files on the remote machine and view them on the local machine, but I will not discuss that process in detail. The machine should be hooked up to a network, and should be able to run network software such as ftp and telnet. The assumptions for the remote machine are similar It should be a Unix type system, so users can log in. Gaussian should be installed, and be accessible for users. This includes setting up the initialization files, as described in the Gaussian Users Reference. You have an account and password on the Unix system. It has a network connection. As for the local system, ftp should be available to users. Step 1 Create an input file. This can be as simple as firing up Gauss. View, building your molecule, and saving it as an input file. Anno 1701 World Editor Chip. However, if you are interested in visualizing surfaces electrostatic potential, orbitals, density, etc., then there will be an additional step you need to take before you save the input file namely, indicating in the input file that you wish to save a formatted checkpoint file. By formatted, I mean human readable, rather than binary. Gauss. View needs to read in formatted checkpoint files, which generally have the extensions. Gaussian does not generate these files by default, but will generate them if the input file indicates that it should. Modifying an input file is a straight forward procedure, and can be done within Gauss. View, from the Gaussian Calculation Setup window. To see that window, from the Gauss. View main menu, choose Calculate Gaussian., and the Gaussian Calculation Setup window will pop up. Exactly what to do in that window is described below. When youve made your modifications, you can save them in a file by clicking on the Retain button in the Gaussian Calculation Setup window, then choosing File Save. Gauss. View main menu. Save it with file type Gaussian, with either a. Gaussian accepts both. Remember the name of the file and the directory you saved it in, youll need to know these later. The easiest way to tell Gaussian to generate a formatted checkpoint file is to add the keyword FORMCHECK to the Additional Keywords box in the Gaussian Calculation Setup window. This tells Gaussian to create a formatted checkpoint file named Test. FChk when the job completes successfully. If the job fails, Test. FChk will not be created. The name of the file will always be Test. FChk. If you need the additional flexibility of a checkpoint file with a different name, then you can simply rename it after the calculation finishes. There is another way, which is somewhat more flexible, to generate a formatted checkpoint file. If you modify your input file so that it has a chk card which is described in Chapter 2 of the Gaussian Users Reference, then Gaussian will not delete the unformatted checkpoint file after the calculation has completed. You can format this checkpoint file using Gaussians formchk utility. Instructions for doing this are included in section 3. Step 3. Run the calculation. You do not need to use the FORMCHECK keyword. If you do, then both the unformatted checkpoint file and Test. FChk will be available at the end of the calculation. Step 2 Transfer the input file to the remote computer. Now that youve saved the input file, you need to transfer it to the remote computer so Gaussian can use it. One way to do this is to use ftp, which is included with Windows, and is available on most Unix machines. Here are the steps to take to transfer the file Get a command prompt. Windows From the Windows task bar the one on the bottom of the Windows screen, click Start Programs Command Prompt, and a command prompt window will pop up. Unix Hopefully, an xterm, or its equivalent is already running. If Gauss. View is running in the xterm, you can either exit Gauss. View, or make it a background process by typing Ctrl Z, then bg at the prompt. Change directories on the local machine. Change directories using the cd command to the directory on the local machine where you saved your input. Remember that on Windows machines, the slashes point the opposite way from Unix machines Windows Unix. Moments Of Spring'>17 Moments Of Spring. Start ftp. Type ftp machine where machine is the name or IP address of the remote machine where youll run the Gaussian calculation. When ftp asks for them, enter your username and password. Change directories on the remote machine. With ftp, use the cd command to the directory where you want the input file to go on the remote machine remembering the different UnixWindows slash conventions Windows Unix. Copy the input file to the remote machine. Once you are in ftp, connected to the remote machine, and in the proper directory there, you can copy the input file to that machine using ftps put command, like this put name. The file will then be copied to the remote machine. Quit from ftp. Thats it now you can leave ftp using the quit command. Step 3. Run the calculation For this step, you need to be connected to a command prompt on the remote machine. Typically the telnet program is used to do this. Log into the remote machine. Again, youll need your username and password.
