Brian

cannot find output file

Hello,

I am attempting to follow the methodology in Tutorial #1 at quantumdynamics.wordpress.com, however when I hit the Simulate button I get the following output after about 1 minute:

“(5042976) Simulation Queued at ncn-g@carter Tue May 27 14:42:22 2014 (5042976) Simulation Complete at ncn-g@carter Tue May 27 14:43:07 2014 (5042976) Simulation Done at ncn-g@carter Tue May 27 14:43:22 2014

# Run two-dimensional spectra

Problem launching job:

Can’t find result file in output. Did you call Rappture ::result in your simulator?”

When I try to compute other outputs, such as exciton coherence or absorption spectra, these fail in a similar fashion too.

I notice that there was a problem like this last year when maintenance temporarily disabled the simulator. Is something like that currently happening?

Thanks!

    Hi Brian, thanks for reporting. I submitted a ticket with the nanohub support crew, I am sure they will fix the problem within the next day or so, probably some maintenance going on. Let us know if you have further issues with the tool, I will update this answer once it runs again. Best, Tobias

        A new CUDA version has been installed on the GPU cluster and the tool has been made available again by the nanohub crew. It runs again, please feel free to send us comments/suggestions. Regards, Tobias

      Hi Tobias,

      Thank you. Unfortunately when I try to run the simulation, using the same parameters mentioned above, it is still reporting a similar error dialogue. It has a couple lines now where it reports “Simulation Running at ncn-g@carter…” that it did not have previously. This time it is running for approximately 10 minutes before it quit, whereas it was only about 1 minute previously, so it seems like something may have been improved but the final outcome is still the same.

        I’d like to add that all the other calculations appear to work now. The only one that doesn’t is the 2d spectrum generator.

        Hi Brian,



        the permission problem for generating the 2d spectra is fixed now and I verified the tool is running.

        Sorry for the delay, I didn't see your message. The nanohub support team suggests to file issues about the tools also directly with them (open a "support ticket"), at least for the cases were an infrastructure problem is suspected.
