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.<br /> For your questions, I use the binary code v1.1 from your website. The sensor mask is a ring with about 256 elements. </p> <p>Thanks!<br /> Xiaofeng </p> http://www.k-wave.org/forum/topic/problem-when-running-kspacefirstorder3d-omp#post-5547 Fri, 24 Jun 2016 11:18:12 +0000 Jiri Jaros 5547@http://www.k-wave.org/forum/ <p>Hi Xiaofeng,<br /> this message usually pops up when there is no free space on the disk drive. </p> <p>Since the output file is rather small, this is suspicious. Could you answer me following questions<br /> 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?<br /> 2. What is the size and shape of the sensor mask? Do you use linear or cuboid sensor mask?</p> <p>If you could share the input file with me, I could take a closer look at the issue. </p> <p>Jiri </p> http://www.k-wave.org/forum/topic/problem-when-running-kspacefirstorder3d-omp#post-5538 Wed, 22 Jun 2016 15:04:08 +0000 xiaofengzhao 5538@http://www.k-wave.org/forum/ <p>Hi all,</p> <p>I have a problem when using kspaceFirstOrder3D-OMP on a linux server. The program would stop in the middle of simulation with the error: </p> <p>terminate called after throwing an instance of 'std::ios_base::failure'<br /> what(): Error: Could not write into "" dataset!</p> <p>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.</p> <p>My question is, is the error caused by the memory limit on the server? </p> <p>Thanks!</p> <p>Xiaofeng </p>
