[mvapich-discuss] Build older version of MVAPICH2-GDR from source

[Panda, Dhabaleswar]

MVAPICH2-GDR library is only available in binary form.

There is a separate user guide for MVAPICH2-GDR. It is available from the MVAPICH project page at the following location: http://mvapich.cse.ohio-state.edu/userguide/gdr/ The link is available from the download page. This user guide has all necessary information. Please take a look at it.

Thanks,

DK

Subject: [mvapich-discuss] Build older version of MVAPICH2-GDR from source

Hi,

How can I obtain source code for an older version of mvapich2-gdr, for instance 2.3.2 ?
Also could you kindly provide the configure flags for building it with gpudirect/gdrcopy feature ?

I could not find the gdr-related section from the main mvapich2 manual.
The only configure flag related to GPU is --enable-cuda, which prints out 'MVAPICH2 GDR Parameters' with MV2_SHOW_ENV_INFO=2. However MV2_USE_GDRCOPY is not shown.

Regards,
Viet-Duc
