Just wondering if anyone can shed some light into an issue we are having with compat-openmpi after upgrading CentOS to version 6.5 Some of our cluster applications are dependent on an older version of OpenMPI, so we are using compat-openmpi. Up to CentOS 6.4 this was version 1.4.3: % /usr/lib64/compat-openmpi/bin/mpirun -V mpirun (Open MPI) 1.4.3 but after the upgrade to CentOS 6.5 it

I'm working with snow and created a local cluster. So far, the same code has always worked (please see below). However, now I receive a message that the connection with the nodes cannot be opened. I restarted my workstation but that didn't help. Is there a known solution for this problem? Thanks a lot for any help. bram foubert library(snow) cl =

Dear R Debian Users: I wrote a quick C program (eventually to become R code) and compiled it as: mpicc -o greet greet.c So far so good. Now when I run mpirun, this happens: erin at erin-laptop:~$ mpirun -np 2 greet ----------------------------------------------------------------------------- It seems that there is no lamd running on the host erin-laptop. This indicates that the LAM/MPI

Dear knowledgeable experts :-), I am trying to get openmpi, Rmpi and SNOW running on a Myrinet/GM cluster. I'm not an IT expert, but I surely could use a working installation of Rmpi and SNOW. I try to load the Rmpi library and get the following: > library(Rmpi) [master:07230] mca: base: component_find: unable to open osc pt2pt: file not found (ignored)

Hello, We have R working with Rmpi/openmpi, but I'm a little worried. Specifically, (a) the -np flag doesn't seem to override the hostfile (it works fine with fortran hello world) and (b) I appear to have twice as many processes running as I think I should. Rmpi version 0.5.5 Openmpi version 1.1 Viglen HPC with (effectively) 9 blades and 8 nodes on each blade. myhosts file contains

After the 7.2 upgrade?boost-openmpi-1.53.0-25 was installed, along with?openmpi-1.10.0-10. ?The old openmpi was then replaced with?compat- openmpi16-1.6.4-10. ?All fine. Except boost-openmpi has a dependency on the old libmpi.so.1 and the new openmpi has libmpi.so.12: # ldd libboost_mpi-mt.so.1.53.0? linux-vdso.so.1 =>??(0x00007ffe8c182000) libboost_serialization-mt.so.1.53.0 =>

I am trying to install the R package "Rmpi" which needs libmpi. I've installed openmpi and lam in Centos 5.2: [root at rab45-1 /]# rpm -qv openmpi openmpi-1.2.5-5.el5 openmpi-1.2.5-5.el5 [root at rab45-1 /]# rpm -qv lam lam-7.1.2-14.el5 lam-7.1.2-14.el5 But I get the following error message when trying to install Rmpi: /usr/bin/ld: skipping incompatible /usr/lib/lam/lib/libmpi.so

Hi list, It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64). When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list I couldn't find any pointers on the net and the same program works with OpenMPI

Greetings. I see a warning message while compiling OpenMPI and would appreciate it if you tell me what it means. This warning happens with any OpenMPI > 1.6.5. Even before starting a cluster, just "sessionInfo" triggers this warning. I'm pasting in the message from R-3.3.2 (this is MRO). Do the R parallel package cluster functions violate the warnings described here? >

Hi all, I'm using RScalapack library for parallelizing some heavy matrix operations required by MCMC methods for spatio-temporal models. The package reference manuals (dated 2005) states that the library needs LamMPI to work but we have a Linux Cluster with OpenMPI. We have found (http://cvs.fedoraproject.org/viewvc/devel/R-RScaLAPACK/) a patch for OpenMPI but we are wondering if in the

Hello together! I've Debian 6.0.3 with OpenSSH_5.5p1 and problem with the execution of remote commands via ssh. It seems as if the first command isn't looked up in all "$PATH" dirs. Here normally I should get the version information of mpirun twice but the first one fails: $ ssh cluster2 mpirun --version ; mpirun --version bash: mpirun: command not found mpirun (Open MPI) 1.4.3

Hi all, now I'm testing R in a "virtual cluster", made it with VirtualBox. This one has 3 nodes, running CentOS 5 and OpenMPI 1.2.8, and the principal node (called "server") exports the /home to other nodes. I have installed R and OpenMPI in /home, in fact, it seems work OK. Editing the openmpi-default-hostfile and run "mpirun -np 3 hostname" I can see the

Many thanks to Dr Yu for updating Rmpi for R 2.6.0, and for starting to make the changes to support Open MPI. I have just built the updated Debian package of Rmpi (i.e. r-cran-rmpi) under R 2.6.0 but I cannot convince myself yet whether it works or not. Simple tests work. E.g. on my Debian testing box, with Rmpi installed directly using Open Mpi 1.2.3-2 (from Debian) and using 'r' from

We have spent some time setting up Sun Grid Engine and OpenMPI on a group of linux boxes. I have created a parallel environment and everything seems to be working. I have Rmpi 0.5.5-5 installed on all machines. I would like to start an interactive R session using, say, 8 processors and then start the Rmpi cluster. I haven't been able to find what needs to be done in order to accomplish

The OpenMPI package that ships with CentOS 5.1 does not seem to be compiled with torque support. It does, however, seem to be compiled with gridengine and slurm support. Would it be possible to get this changed?

Has anybody tried to use Rmpi with the OpenMPI library instead of LAM/MPI? LAM appears to be somewhat hardcoded in the Rmpi setup. Before I start to experiment with changing this, has anybody else tried Rmpi with non-LAM MPI implementations?
