[Pw_forum] QE-GPU compilation problems

Thank you for your kind replay.
This GPU (Tesla C1060 / M1060) may be old and computation may be poor compared to todays GPUs but still the combined speed (we have 4 nos) could be more than multi core cpus. Even though the current QE-GPU is not supported on this GPU
it successfully compiled but while invoking pw-gpu.x following errors is obtained
" ***WARNING: unbalanced configuration (1 MPI per node, 5 GPUs per node)
Error in (first zero) memory allocation , program will be terminated!!! Bye... "
can you please guide me to properly allocate memory between GPU and CPU or per node (2 nodes, 8 -cores/node)
with thanks and respectful regards

those cards are very old (4 years or maybe 5 year) and have compute capability 1.2. Supporto of double-precision is very poor, QE-GPU does not support those cards anymore.
