mountfs and open cellview to edit

Assuming you really do have write access, what kind of file system is the data stored on? Note that this is presumably a library that is not part of the Cadence installation.

It's important that the file system supports links (both hard and symbolic links).

Also, which subversion of the tools are you using? Help->About will tell you this.

This is something that would be best answered through a support channel such as http://support.cadence.com or (assuming you're from a University) through your university program (e.g. in Europe, maybe through the Europractice scheme).

Hi Andrew, thanks for the reply.

Can you please clarify what you mean by "kind of file system"?

Both Cadence installations are IC617, latest ISR (022?).

My local OS is CENTOS6. 10. I use sshfs to mount a directory, let's call it "project" from an RHEL6 machine.

"Project" is the parent directory to both "my_env" and "design" libraries. "Design" has all my design views. "My_env" is my *usual* startup directory, with cds.env, cds.init etc which is used when I'm actually working on the remote server. *it is NOT used when mounting locally*.

To start virtuoso locally I created a local copy, "my_env_loc" which points to *my* local Cadence installation instead of the remote one so I can experiment with it.

Another thing that I noticed which I don't know if related, is that when I'm running Cadence locally and running ADE-L I cannot see the (remote) saved states. Moreover, on the "load state" menu, the pull-down tab that usually allows me to explore simulation states of other cells from other directories, shows only the current cell/dir.

My University is in the US. I can contact Cadence  support but it will require doing it through  our admins, which are not Cadence experts. A previous issue took a very long time to solve, so I prefer to first try on my own.

Hi Matan,

Put simply, we do not do any testing with sshfs nor or aware of any customers that are using it. I found some questions to R&D from about 4 years ago when they had tried some limiting testing of OpenAccess using fuse-based file systems such as sshfs, but then a later one which said that we have no set up and no plan to try to support this. It's unclear whether the sshfs approach supports all of the mechanism we used to open files in libraries, and this may lead to issues such as those you're seeing. There have been hardly any requests about sshfs that I can see (literally a handful) and 4 of those came from 2 different universities (one in the US). One of the requests was nothing to do with Virtuoso. 

So you're using an unsupported mechanism to mount files, and I think you'd be better off using something more mainstream (such as NFS).

Andrew.

Thanks Andrew for the reply.

For now, I've given-up trying to solve these sshfs issues. The challenge with NFS is that it requires to enable my user access in the server by the admins - which I'm not sure possible for security reasons. If you have any other ideas as to how to mount my remote directory without admin permissions it'd be great, but if not  - it is what it is.

Thanks!

Hi Matan,

This is a bit odd - I work with a lot of companies who have quite severe security restrictions, and I've not seen any insisting upon using sshfs rather than NFS. I'm not sure why an admin would prevent access to software and project data with appropriate permissions - it sounds as if your university has an unusual infrastructure! Anyway, good luck - hope you manage to get this worked out so that things behave in a supportable fashion.

Regards,

Andrew.
