Thank you for your response! For future reference, it was a memory issue but not with disk space. I deleted over 1TB of files and the issue persisted. The issue ended up being the RAM available during the simulations, so I just increased the number of nodes I requested and the issue went away. ________________________________ From: Oscar Baseggio <[email protected]> Sent: 28 April 2026 02:10 To: Sosa, Luis A <[email protected]>; Quantum ESPRESSO users Forum <[email protected]> Subject: Re: turboMAGNON error opening V0psi files
Dear Luis, The error occurs when you create the files. They are very large, so you need to check if you have enough disk space. The size of those files is: nwordd0psi = 4 * nbnd_occx * npwx * npol * nksq nbnd_occx = maximum number of distributed bands npwx = maximum number of distributed plane waves npol = 3 nksq = number of distributed k points All for 8 bits. best, Oscar Baseggio ________________________________ From: users <[email protected]> on behalf of Sosa, Luis A via users <[email protected]> Sent: Monday, April 27, 2026 7:31 PM To: [email protected] <[email protected]> Subject: [QE-users] turboMAGNON error opening V0psi files Hello all, I am trying to run a turboMAGNON (QE 7.5) simulation of MnPS3 but I am having issues getting it to start. I already ran an SCF calculation but when I run turbo_magnon.x I get the following error: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Error in routine diropn (20): error opening ./tmp/tmp_magnons/MnPS3.V0psi.138 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Plus the same error for about 20 other V0psi files in the range of 135-164 (but not all files in that range). I checked the files that present the error and they are all empty, so it seems like it could be an error in generating the files? Any guidance on how to solve this would be much appreciated. I attached my scf input and output, as well as my turbo_magnon input and output. Best regards, Luis Sosa Graduate Research Assistant Microelectronic Research Center, University of Texas at Austin
