[mvapich-discuss] --enable-cuda=basic when building with PGI compiler set

[Maxim Milakov]

Hi,

I am building MVAPICH2 1.9 using PGI 13.5 accelerator:

CPPFLAGS="-D x86_64 -D__align__\(n\)=__attribute__\(\(aligned\(n\)\)\) 
-D__location__\(a\)=__annotate__\(a\) -DCUDARTAPI=" F77=pgf77 FC=pgf90 
CC=pgcc CXX=pgcpp ./configure 
--prefix=/home/max/software/pgi_specific/mvapich2 --enable-f77 
--enable-fc --enable-cxx --enable-cuda=basic --with-cuda=$CUDA_PATH 
--disable-mcast --enable-shared --disable-static

I am specifying --enable-cuda=basic as configure script fails otherwise 
(and "basic" was suggested here, in the user group some time ago).

I am wondering in what degree I am limiting myself with this 
"--enable-cuda=basic"... Will I be able to pass device pointer to mpi_send?

Thanks!
