execvp error

[gadelha__alexandre]

Gentlemen, could you please help with an issue?

I´m using intel compiler ifort version 18.0.2 and intel mpi version 2018.2.199 in a attempt to run WRF model on HPE (former SGI) ICE X machine.

wrfoperador@dpns31:~> ifort -v
ifort version 18.0.2

wrfoperador@dpns31:~> mpirun -V
Intel(R) MPI Library for Linux* OS, Version 2018 Update 2 Build 20180125 (id: 18157)
Copyright 2003-2018 Intel Corporation.
wrfoperador@dpns31:~>

When I run the executable I receive the following message:

Could you help me to solve this problem?

Thanks for your attention. I´m looking forward to your reply.

Hi everybody, issue SOLVED!

I found the problem. Actually I use to use the SGI MPI (MPT) and with that I only needed to write the following:

mpirun r1i2n0 12 ./geogrid.exe

but since I´ve compiled with intel mpi now I need to set:

mpirun -host r1i2n0 -np 12 ./geogrid.exe

Now I need to know how to set multiples nodes!!!!!
