Dear Filippo

Thank you very much for your reply.I have compiled qe-gpu 14.10.0 with
espresso-5.1.2 successfully(only serial).When i give the following
command,it shows
anubhav at priyank-ThinkStation:~/Downloads/espresso-5.1.2/GPU/PW$ ./pw-gpu.x

     *******************************************************************

       GPU-accelerated Quantum ESPRESSO (svn rev. unknown)
       (parallel: N , MAGMA : N )

     *******************************************************************
Error in memory allocation, program will be terminated (2)!!! Bye...

I run a simple scf calculation as a test by the following:

anubhav at priyank-ThinkStation:~/Downloads/espresso-5.1.2/GPU/PW$ export
PHI_DGEMM_SPLIT=0.975
anubhav at priyank-ThinkStation:~/Downloads/espresso-5.1.2/GPU/PW$ export
PHI_ZGEMM_SPLIT=0.975
anubhav at priyank-ThinkStation:~/Downloads/espresso-5.1.2/GPU/PW$ pw-gpu.x <
si.scf.in > si.scf.out
It gives
Error in memory allocation, program will be terminated (2)!!! Bye...

Can you help me why i am getting this error.I have NVS310 GPU with 512mb
memory.
Thanks in advance.
