Hi, 

 

I am having a hard time getting Rmpi to start up on XP. 

 

 

Firstly, tried the the DeinoMPI route, loaded DeinoMPI and created store
credentials.

 

As soon as I load Rmpi from R (require(Rmpi)), I get the following pop
up: "This application has failed to start because deino_mpich2mpi.dll
was not found. Re-installing the application may fix this problem."

 

That dll is nowhere to be found, including in the install directory of
DeinoMPI. In R itself it gives me an error of not being able to load
'Rmpi.dll'; the file is in the directory it looks for and I also
included that directory in my system Path.

 

I tried to re-install DeinoMPI etc. but that did not work. I think it
might be an issue with security settings and DeinoMPI, because when
loading DeinoMPI and selecting my local box (after creating store
credentials) I get the message "DeinoMPI is not installed" even though I
am running DeinoMPI on that same box.

 

Secondly, I try using the Rmpi version that's built for MPICH2. in
wmpiconfig.exe I see my local box come up in green so clearly installed
- I set localonly to 'yes'. I then launch wmpiexec.exe and select
Rgui.exe as the application (in 'more options' I type '-localroot' ;
makes no difference if I don't by the way). I click Execute and Rgui
starts up. In R, I type require(Rmpi) and R starts hanging. I end the
Rgui.exe program.

 

I the wmpiexec.exe I get the following message: 

"Error posting readv, An existing connection was forcibly closed by the
remote host.(10054)

accepted a socket on a listener not associated with a process struct.

SMPDU_Sock_wait returned an event with a NULL user pointer."

 

 

Does anybody know how to solve either of those two problems in XP ?
