[mvapich-discuss] Is negative host_id number from gethostbyname() a problem?

[Terrence.LIAO at total.com]

Dear Mvapich,

I am building mvapich-1.1rc1 for infinipath HTX card with CentOS5.2 and 
OFED1.4 using make.mavpich.gen2.  The build is successfully, but the run 
fails,  it never passes the MPI_Init().  It seems fall into an infinite 
loop.   I check the gethostbyname() using this code
                 struct hostent *he;
                 he = gethostbyname (myname);
                 int host_id = ((struct in_addr *) 
he->h_addr_list[0])->s_addr;
                 printf("host_id: %d\n", host_id);

and get 
                host_id: -486364992

Will this the root cause, and any advice what I should do to fix this 
problem?


Thank you very much.
