<p class="MsoNormal"><span style="font-family:"Courier New"">Dear All (I've sent this already with another email-account, not subscribed to the list)<br>
<br>
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<br>
<br>
for (i in c(1:102))<br>
{ans.basicI[[i]] <- siena07(basic.modelI[[i]], data = mydata.basic.model[[i]], effects = myeff.basic.modelI[[i]], batch = T, nbrNodes = 14, useCluster = T);<br>
sink(paste("basic.modelI.",i,".txt"));<br>
show(ans.basicI[[i]])<br>
sink()}<br>
<br>
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:<br>
<br>
<i>Start phase 2.1<br>
Phase 2 Subphase 1 Iteration 1 Progress: 4%<br>
Phase 2 Subphase 1 Iteration 2 Progress: 4%<br>
Error in checkForRemoteErrors(lapply(cl, recvResult)) : <br>
14 nodes produced errors; first error: Unlikely to terminate this epoch: more than 1000000 steps<br>
In addition: There were 16 warnings (use warnings() to see them)<br>
> warnings()<br>
Warning messages:<br>

2: closing unused connection 16 (<-localhost:10187)<br>

15: In rbind(`1` = 2691L, `2` = integer(0), `3` = integer(0), ... :<br>
number of columns of result is not a multiple of vector length (arg 25)<br>
16: In rbind(`1` = integer(0), `2` = integer(0), `3` = integer(0), ... :<br>
number of columns of result is not a multiple of vector length (arg 37)</i><br>
<br>
The loop works fine up to i=16.<br>
<br>
Excerting the code on my Mac works fine...Do you have an idea what could cause the problem?<br>
<br>
Thank you for your help.<br>
<br>
Best,<br>
Philippe</span> <o:p></o:p></p>
