[Rsiena-help] RSiena: Error using multiple processors

[Philippe Sulger]

Dear All (I've sent this already with another email-account, not 
subscribed to the list)

I am running a siena07 analysis on 102 networks. I do this via a loop 
and I am using a server with 16 cores. The command I enter is

for (i in c(1:102))
     {ans.basicI[[i]] <- siena07(basic.modelI[[i]], data = 
mydata.basic.model[[i]], effects = myeff.basic.modelI[[i]], batch = T, 
nbrNodes = 14, useCluster = T);
     sink(paste("basic.modelI.",i,".txt"));
     show(ans.basicI[[i]])
     sink()}

As you note, I decided for the time being to use only 14 cores. This 
also gives me some txt-files with basic estimates. Also if I exclude the 
sink()-txt-sink() part I receive the an error that looks as follows:

/Start phase 2.1//
//Phase 2 Subphase 1 Iteration 1 Progress: 4%//
//Phase 2 Subphase 1 Iteration 2 Progress: 4%//
//Error in checkForRemoteErrors(lapply(cl, recvResult)) : //

//In addition: There were 16 warnings (use warnings() to see them)//

//13: closing unused connection 5 (<-localhost:10187)//
//14: closing unused connection 4 (<-localhost:10187)//
//15: In rbind(`1` = 2691L, `2` = integer(0), `3` = integer(0),  ... ://
//  number of columns of result is not a multiple of vector length (arg 
25)//
//16: In rbind(`1` = integer(0), `2` = integer(0), `3` = integer(0),  
... ://
//  number of columns of result is not a multiple of vector length (arg 37)/

The loop works fine up to i=16.

Excerting the code on my Mac works fine...Do you have an idea what could 
cause the problem?

Thank you for your help.

Best,
Philippe
