Dear Janardhan,
<div class="moz-cite-prefix"><br>
even if you also fix the following problem (init function) you
will dump into a series of problems just afterword.<br>
There is no arm of using 1060 GPUs on your HW configuration for
double precision based applications such as QE.<br>
<br>
For the sake of giving you an answer, if you have 8 cores nodes
and 2 GPUS per node you can use 2 MPI per node and 4 OMP thread
per process.<br>
<br>
For more information about how to execute QE-GPU in your system,
please contact me personally as this topic is longer of interest
of this mailing list due to the "old" HW we are considering. <br>
<br>
Kind Regards,<br>
<br>
Ivan<br>

can you please guide me to properly allocate memory between
