Hi! I'm trying to download the SDDS Toolkit for Ubuntu 18.04, but I get a "Not Found" error regardless of where on the site I try to download from. It just says "The requested URL /downloads/SDDSToolKit-3.6-1.ubuntu.18.04.x86_64.rpm was not found on this server.". I need to reinstall asap since it s...

Hi Michael,

I tried implementing it this way, but I get the error
Do you know what causes this?

Hi! So, I finally got around to trying this a little while ago. I have a case with more magnets and drifts (4 and 5, respectively), so I implemented the final drift as a co-variable similarly to what's described below. The problem is that I couldn't find a way to prevent this drift from getting nega...

Hi, So now I have tried with the usleep_mpi_io_kludge=10 option and got the error there too. The mpi_io_force_file_sync=1 is so slow that I'm not expecting to see it crash (if it does) for many hours. It took a few hours with the first option for it to crash, and that ran significantly faster. I hav...

Hi again,

It seems that I spoke too soon, the problem is still there but took quite a bit longer to show up. I will try running with the two options in &global_settings, but it will take a bit of time to verify if this does anything.

Hi again, So, I finally got around to updating the elegant version to the latest one, and this alone seemed to solve my issue; I can't reproduce the error anymore. Maybe some file got corrupted, I previously had a problem with corruption of my rpn definitions file on that machine. Anyways, thanks fo...

Hi again,

The code doesn't recognize the commands you suggested, it says that the known variables for global_settings are all those listed in the manual, except those two.

Michael, I'm not exactly sure which partition is which on my machine, they are not assigned any label, but the file system type seems to be vfat. If it's not that, it's ext2 or the oddly named LVM2_member. I have had problems with other things (serial) on this machine recently, and I think you got m...

Hi, I'm currently running a serial optimization and tracking ~60k particles in Pelegant. It runs well for a while, then crashes with the error message SDDS_MPI_FlushBuffer(MPI_File_write_at failed): MPI_ERR_IO: input/output error Error: Unable to update page--file pointer is NULL (SDDS_UpdateBinaryP...

Hi!

So, I'd like to vary some quad positions on an overall fixed distance, i.e. vary the drift lengths between them while keeping the sum of the lengths constant. How would I implement this in elegant?

Best regards
