Reply To: Problem with multi GPU

Hello,
I’m still on it but now I got this message when I make the file
“nvcc cavity3d.o -o cavity3d -lolbcore -L../../../external/lib -lmpi_cxx -lmpi -lpthread -lz -ltinyxml -lcuda -lcudadevrt -lcudart -L../../../build/lib
/usr/bin/ld: cannot find -lmpi_cxx: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [../../../default.single.mk:38: cavity3d] Error 1
”
I know the message from the directory but last time I can run but now it has the problem. Could you help me in this situation?
Thanks
