hi all! |
2 |
|
3 |
May be it will be better if we can choose combinations mpi_imp/compiler |
4 |
for example |
5 |
mpi-openmpi-gcc |
6 |
mpi-openmpi-intel |
7 |
and so on |
8 |
|
9 |
for now it can be done manualy specifing CC, Fc and so on env |
10 |
may be it will be better if it will be done from empi? |
