Re: [Rd] Rmpi on CentOS (64bit)
There are many different versions of OpenMPI about. It looks like you
have one that is set up for specialized hardware. Either this is the
wrong version or a configuration error, and you will need to talk to
your 'local System Administrator'.
Incidentally, you should not have to set LD_LIBRARY_PATH, but I
frequently have had to add configuration files in /etc/ld.so.conf.d,
including for openmpi on Fedora 12. On Fedora 10 (but not 12) MPI was
under the /etc/alternatives mechanism, and had other problems. I
currently have
gannet% cat /etc/ld.so.conf.d/openmpi-x86_64.conf
/usr/lib64/openmpi/lib
on F12.

Re: [Rd] Installation problem with 2.10 and Solaris 10 (PR#14227)
On Tue, 2 Mar 2010, jno...@vcu.edu wrote: Full_Name: John Noble Version: 2.10 There is no such version of R (see the posting guide for the need for accurate reporting of version numbers). In 2.10.1, the unpacking is usually done by either by tar xf or gzip -dc | tar xf so the behaviour of gzip -d without -c is not relevant. As R 2.10.0 and 2.10.1 have been built on many Solaris 10 systems, by far the most likely issue is a configuration problem on yours. One possible workaround (not needed on our Solaris boxes) is to set the environment variable TAR to a GNU version of tar that supports unpacking compressed archives directly: R will then call that tar. OS: Solaris 10 SPARC Submission from: (NULL) (128.172.190.27) The make of Recommended fails. All sections of Make work up to this point and the compiled version of R appears to be correct. Only when adding the recommended modules does the problem appear. Do you mean the 'recommended packages': there are 'modules' and that is not what is being installed at this stage? The best I can figure the problem appears to be related to the fact that gzip will not decompress linked files without the "-f" option. Not the whole story ... but what version of gzip is this? Sample output follows: # make make[1]: Entering directory `/home/jnoble/R-2.10.1/src/library/Recommended' begin installing recommended package boot ERROR: cannot extract package from 'boot.tgz' make[1]: *** [boot.ts] Error 1 make[1]: Leaving directory `/home/jnoble/R-2.10.1/src/library/Recommended' make: *** [recommended-packages] Error 2 The boot.ts.out file contains: # more boot.ts.out ERROR: cannot extract package from 'boot.tgz' If I try to run the command that the Makefile appears to be running by hand I get the following: # ../../../bin/R CMD INSTALL -l "../../../library" boot.tgz ERROR: cannot extract package from 'boot.tgz' Oddly, the following happens with the latest gzip: gzip -d boot.tgz gzip: boot.tgz: Number of symbolic links encountered during path name traversal exceeds MAXSYMLINKS That is as expected, but where did you get the idea that gzip -d is used in that fashion? The most likely command used, gzip -dc boot.tgz | tar xf - works for e.g. gzip 1.3.5 (which is what our Solaris 10 system has in /usr/bin) and 1.3.12. This can be corrected with the "-f" option but I can't pass that into "R". Actually, you can: the gzip command used is set by R_GZIPCMD. But you do not want to here.

He knows less about it (MPI, at least) than I do. Perhaps this is
'specialized hardware' in that it's a dual quad-core processor machine

I notice that my Fedora installation has no dat.conf file. Perhaps
it pertains to something special on the CentOS machine. I can't

A similar issue once arose on Debian as we built Open MPI with the IB libs even though most people don't have suitable Inifiniband hardware. In our case that lead to a noisy warning; upstream later suppressed the warning given certain conditions. You could try to suppress the probe for IB which we did (in the older 1.2.* series of OpenMPI) via # Disable the use of InfiniBand # btl = ^openib btl = ^openib in /etc/openmpi/openmpi-mca-params.conf Hth, Dirk -- Registration is open for the 2nd International conference R / Finance 2010 See http://www.RinFinance.com for details, and see you in Chicago in April! __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Yes. For that reason, I wished to get Rmpi working on CentOS. I use
Fedora 11 at home and I'm a bit put off by the 300-500 Mb of updates
most weeks. It's nice using the new stuff, but those updates
periodically screw up what had been working well. I wouldn't want
that on a production machine. Looks as though I'll have to do so
anyway. My Linux skills aren't up to sorting out this CentOS lot, and
I should at least get it started: it's likely there's not much
difference between F11 and F12 for this task.
This could well be a case where Debian would be the easiest way to go,
but I couldn't convince the IT people to go down such a new track.
Ours is very much an rpm site. In any case, my only Debian-type
experience is with Mepis (where I got Rmpi working in 20 minutes, but
I don't think that makes me a Debian pro).
Thanks for the hints.

Re: [Rd] Mentor for GSOC '10: Symbolic Regression in R
Hello, I can't offer to mentor because I don't know anything about symbolic regression. However, since you have R/C++ as the skills requirements, I would strongly recommend that you use Rcpp as an enabling technology, so that you can be productive on C++/symbolic regressions as opposed to manage R API quirks. Also, you can count on some implicit support through Rcpp mailing list. https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel Good luck finding a mentor, this sounds like a cool project.
