OPT Downloads
The following packages are available for you to download.
We advise reading the document on compatibility and compilation options, OPTMPICompat.pdf which is in the doc subdirectory of the OPT installation.
If you are upgrading from 1.1 or later, you should upgrade - rather than install - if you wish to maintain your data. You will be given this option during the usual install.sh script. For upgrading from older versions, please reinstall or contact support.
Important note for Infiniband users
The Infiniband interconnect does not support the fork() system call.
After installing OPT, edit ${OPT_ROOTDIR}/opt/etc/opt.conf and add the line:
fork=no
