Veda2.0 works on Windows portables, desktops, servers, and VMs, with Windows 8/Windows server 2012 or above. Microsoft Excel is a prerequisite. Hardware needed depends on the size and complexity of models, but here is a configuration suitable for typical TIMES models under Veda2.0:
CPU: Minimum 4 cores are recommended for STANDARD and ADVANCED licenses. 8 - 16 would be desirable for larger models.
RAM: 4-8 GB is enough for Veda, but GAMS needs more RAM for larger models. 32 GB would accomodate most models.
HDD: 500GB - 1TB free space for Veda and GAMS files.
- Veda accesses Internet for the following functions:
Source: provided on request
- Displaying announcements on the Start page
- Updating TIMES source code from Github
- Download Veda
It is recommended that the new user first takes a look at the video:
- There are two ways to go about it:
- Localhost: This just needs to be extracted.
- Download and install prerequisites
Give full read and write permissions to the folder where it is extracted.
Port 5432 should be accessible to PostgreSQL.
- Installer: This is a setup executable.
Create a folder where you wish to install and give it full read and write permissions.
Port 65000 should be accessible to PostgreSQL.
Getting a Trial license¶
If you have registered an evaluation version request on the ETSAP website, then you would already have a Trial license key. If not, you can get one as shown here.
Once setup, to start using VEDA2.0, the user is required to get licence. Launching Veda will present an Activation screen:
- If you don’t have the Trial key:
Click ‘Get Trial Key’
Complete the Registration form to get Trial key by email
Paste it into the Activation form, and request Activation. This will then bring you to the VEDA2.0 Start Page, if activated successfully.
Setting up GAMS¶
As part of registering VEDA2.0 a request is sent to the ETSAP Liaison Officer who will arrange for an evaluation GAMS license file to be created, sending it to the new user along with the download and install procedures here:
Copy the GAMSLICE someplace on your computer.
Head to http://www.gams.com/download/ and select the Windows download option for either Win-64/32, as appropriate
Run Setup by clicking on it in Windows Explorer
Check “Use advanced installation mode” at the bottom of the GAMS Setup form.
Let GAMS get installed into the default folder (GAMS<Win#><ver>.
Check the Add GAMS directory to PATH environment variable.
Have the GAMSLICE.TXT copied from wherever it currently resides.
You may need to restart your computer to have the GAMS Path activated.
Once you have VEDA installed you can try a TIMES model run.
If you installed Veda 2.0 using installer, the process of uninstalling is very straight forward.
Go to Control panel.
Select Veda 2.0 and click uninstall.
Make sure that Postgres has also been removed. Usually the process of uninstallation also removes Postgres from the computer.
Sometimes uninstallation ends prematurely (image below) and Postgres is not removed. In such case, please go to Uninstalling Postgres for further instructions.
Launch the Veda2.0 version you are using.
In the main menu -> Model –> Stop server and exit
Now you can go ahead and delete the localhost directory.
Backup and Restore¶
The Backup and Restore feature makes upgrading Veda much easier. You can back up the “state”, meaning, all models that are synchronized, and all Cases that are imported in Veda. This is available starting version 230.
