[ofiwg] libfabric fi_getinfo question

[Vasiliy Tolstov]

Hello, i'm try to understand usage of libfabric and stuc at simple
example, it returns
fi_getinfo(): info.c:34, ret=-22 (Invalid argument)

i'm try to resolve local node address with hostname =
cn33.z1.mn2.simplecloud.ru and node_desc = cn33.z1.mn2.simplecloud.ru

P.S does it possible to resolve node address via libfabric that
entered in node_desc
(/sys/devices/pci0000:00/0000:00:02.0/0000:02:00.0/infiniband/mlx4_0/node_desc)

int main(int argc, char **argv) {
        int ret;
        hints = fi_allocinfo();
        if (hints == NULL) {
          fprintf(stderr, "%s\n", "failed to alloc info");
          return -1;
        }
        hints->addr_format = FI_SOCKADDR_IB;
        ret = fi_getinfo(FI_VERSION(1, 0),
"cn33.z1.mn2.simplecloud.ru", NULL, 0, hints, &fi);
        if (ret < 0) {
                FT_PRINTERR("fi_getinfo", ret);
                return ret;
        }
        if (fi == NULL) {
                fprintf(stderr, "%s\n", "failed to get info");
                return -1;
        }
        for (rp = fi; rp != NULL; rp = rp->next) {
                if (rp->addr_format == FI_SOCKADDR_IB) {
                        addrlen = fi->dest_addrlen;
                        remote_addr = malloc(addrlen);
                        memcpy(remote_addr, fi->dest_addr, addrlen);
                }
        }
        fi_freeinfo(fi);
        return 0;
}
