Request for help

Dear All
Few problems facing with openmolcas
I used the command
>>export MOLCASmem=10240
>>export MOLCAS_NPROCS=2
but the following message is obtain for every module (SCF,GATEWAY SEWard RASSCF)

()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()

                                              &RASSCF

                                   only a single process is used
                       available to each process: 2.0 GB of memory, 1 thread?
()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()

========================================================================
2. SCF converges for smaller basis set but when I used bigger basis functions (small basis aug-cc-pvdz bigger aug-cc-pvtz)

Re: Request for help

It's MOLCAS_MEM, not MOLCASmem. In order for MOLCAS_NPROCS to have any effect, you need to compile with MPI=ON, for which you need GlobalArrays.
