   Hi all,

   I have a problem when using kspaceFirstOrder3D-OMP on a linux server. The program would stop in the middle of simulation with the error:

   terminate called after throwing an instance of 'std::ios_base::failure'
   what(): Error: Could not write into "" dataset!

   The grid size is 512*512*161*2200 (nx*ny*nz*nt). There would be no error if I run the simulation with a local windows computer. The peak memory used is about 2.8GB and the final output is about 8MB. And if I reduce the grid size to 512*512*21*2200 (nx*ny*nz*nt), then it also could work on the linux server.

   My question is, is the error caused by the memory limit on the server?

   Thanks!

   Hi Xiaofeng,
   this message usually pops up when there is no free space on the disk drive.

   Since the output file is rather small, this is suspicious. Could you answer me following questions
   1. Do you use our binary or did you compile the code by yourself? If you compiled the code, what HDF5 version did you use?
   2. What is the size and shape of the sensor mask? Do you use linear or cuboid sensor mask?

   If you could share the input file with me, I could take a closer look at the issue.

   Hi Jiri,

   Thanks for your reply. Now I am able to run the simulation multiple times with other linux servers. So the problem should only be related to the previous server itself, or the net drive that I used to save the data.
   For your questions, I use the binary code v1.1 from your website. The sensor mask is a ring with about 256 elements.

   Thanks!
