Old SLEPc Releases
Note: These are very old releases of SLEPc. They are here for historical reasons. Recent versions can be found at the download page.
The software is free for academic and research use. This means that if you work in an academic or research institution such as a University or a government laboratory then you can use the software without formally requiring a license.
For commercial use, you need to sign a software license agreement. This includes all users working for a private company, even if the software is going to be used only for in-house research activities. A reasonable testing period is allowed before asking for the license. Normally, we license the software without a fee, but this has to be concerted individually.
In both cases, please note the following. This software is provided 'as is', with absolutely no warranty, expressed or implied. Any use is at your own risk. In no event will the authors be liable for any direct or indirect damages arising in any way out of the use of this software. The user will acknowledge the contribution of the software in any publication of material dependent on its use. The user can modify the code but at no time shall the right or title to all or any part of this software pass to the user. A modified version of the software cannot be redistributed. This software (or a modified version) may not be sold.
Note: For 2.3.3 and older releases, apply the patch with GNU patch command in the SLEPc root directory as
