Thank you very much.
I check the status of 2027 and 2028 bugs.

I am open to test fixes for these two bugs.

If you run into any issues, please email me. NE020 supports Mvapich,
Mvapich2, OpenMPI, Intel MPI and HP MPI.

Hi Amir,
Hi Chien,

I understand that the bug 2027 could be solved next week, so I will test
SDP protocol performance on NE020 cards.
Is it correct?
If yes, could you point out the code modifies?

Keep in touch and take care.
Regards,
Andrea
