[OMPI devel] portability problem in ompi_info
Hi again, there is a tiny portability problem located in ompi/tools/ompi_info/param.cc. This code uses the asprintf() function, which is a GNU extension and therefore not very portable. Fortunately, it is not hard to exchange the line asprintf(&value_string, "%d", value_int); with a separate buffer allocation and the ANSI C function sprintf() (although I'd prefer a pre-allocated buffer). Tip: an integer (whether signed or unsigned) has at most ceil(sizeof(int)*2.41) decimal digits (don't forget the trailing null byte!). Christian PS: Thanks Jeff for filing the last bug I've mailed.
Re: [OMPI devel] portability problem in ompi_info
We actually have a portable version of asprintf() in the OMPI code base. On platforms that don't support asprintf(), the configure magically swaps in the OMPI equivalent. See opal/util/printf.c.

[OMPI devel] [IPv6] ORTE layer working
Hi, I'm glad to announce a first working version of IPv4+IPv6 orte. It contains: - IPv6 interface discovery on Linux - a single orte/mca/oob/tcp component - a single module (no multiple instances) - two listening sockets - two connecting sockets The listening sockets always stay open, the connecting sockets are tried concurrently and if one succeeds to connect (a real orte connect, mca_oob_tcp_peer_connected()), the other one will be closed. Of course, Jeff's ipv6-configure-patch is also included. This work is still based on OpenMPI-v1.1, but I'll port it to the v1.2 svn checkout, hopefully until the end of the week ;) It will then appear in the svn-/tmp/. If someone is interested in the code right now, I could create a snapshot of my svn working copy and put it on the webserver. -- mail: a...@thur.de http://adi.thur.de PGP: v2-key via keyserver Die deutsche Telekom ist eine Organisation für Radsport.

[OMPI devel] ORTE workshop
For the benefit of those not on the call today, we agreed to have the ORTE "workshop" Thursday and Friday, 9/28-29/2006 in Los Alamos. Details on location, and schedule will be coming out in the next couple of weeks. As was mentioned on the call, we will try and have this meeting available on the Access Grid. If there will be any non-US citizens coming for this, and you don't have LANL paperwork in place, we will need to get this in by tomorrow, 9/13/2006, otherwise you will not be able to come to this meeting (there may be individual instances that we may not be able to accommodate). If you fall into this category, please send an e-mail request to ccs-...@lanl.gov, and copy me, so that we can start this paperwork. Thanks, Rich
