Hi Yanfei， I ask this question months ago，but I was told IPv6 is supported in mpich 3.*. So it's not supported? Thanks Shuwei On Wed, 6 Dec 2017 at 11:24 Guo, Yanfei <[email protected]> wrote:

Hi Carlos,

MPICH currently uses gethostbyname which does not support IPv6, therefore it won’t work on a pure IPv6 network.

Best,

Is it possible to use mpich (3.3) with IPv6-only? We tried it here and got

Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(506)..............: MPID_Init(211).....................: channel initialization failed MPIDI_CH3_Init(89).................: MPID_nem_init(324).................: MPID_nem_tcp_init(178).............: MPID_nem_tcp_get_business_card(425): ckpt_restart(384)..................: gethostbyname failed, zuratkul (errno 4) *************

This shows that mpich doesn't run without IPv4, which is our case... Is there a way to make it work in this situation? _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
