[mvapich-discuss] mvapich2 1.7rc1 and 2GB transfers

[Devendar Bureddy]

Hi Tibor

Thanks for your sample program. There is a interger over flow inside
the library.  Can you please apply attached patch and try again.
Please do  a "make clean" and "make && make install" after applying
the patch.

BTW, You have declared a large memory for buffer2 but not used it in
your sample program.

Thanks
Devendar
