Hi, when using the --send-data option for an MPI block, it seems that each of the MPI processes prints out a data-loading message (presumably using "open" internally). For example, I'm getting stuff like this with an mpisize of 4: gretlmpi 2021c-git Aktuelle Sitzung: 2021-08-17 15:42 Lese Datendatei C:\Users\<...>\AppData\Roaming\gretl\mpi-data.gdt Lese Datendatei C:\Users\<...>\AppData\Roaming\gretl\mpi-data.gdt Lese Datendatei C:\Users\<...>\AppData\Roaming\gretl\mpi-data.gdt Lese Datendatei C:\Users\<...>\AppData\Roaming\gretl\mpi-data.gdt It would be nice if this were somehow configurable, perhaps with a quiet or silent switch or something like that. Not necessarily right now, but before I upgrade to an 8-core machine and the redundant output gets really long ;-) thanks sven
