Hi (Michael)

When I run models/nightly/BootstrapParallelNightly.R

I get:

> modelResults <- mxRun(topModel, silent=TRUE, suppressWarnings=F)

Error in checkForRemoteErrors(val) :

5000 nodes produced errors; first error: unused argument(s) (useOptimizer)

Has there been a change which affects this argument?

Cheers

Mike

Umm, I'm not getting any errors when I run this on the latest OpenMx from the svn trunk. If you are running the script on a cluster, you will have to ensure that the OpenMx version on the interactive node of the cluster is the same as the OpenMx version on the compute nodes of the cluster.

I took the nuke option wrt OpenMx:

mv OpenMx OpenMx.old

svn checkout --username me http://openmx.psyc.virginia.edu/svn OpenMx

cd OpenMx/trunk

sudo make install

run again

same errors (maybe warnings only?) - though it does seem to run ok:

Error in checkForRemoteErrors(val) :

1000 nodes produced errors; first error: unused argument(s) (useOptimizer)

3: omxLapply(independents, mxRun, intervals = intervals, silent = silent,

suppressWarnings = suppressWarnings, unsafe = unsafe, checkpoint = checkpoint,

2: runHelper(model, frontendStart, intervals, silent, suppressWarnings,

unsafe, checkpoint, useSocket, onlyFrontend, useOptimizer)

1: mxRun(topModel, silent = TRUE, suppressWarnings = TRUE)

One thing that's a bit odd though. When it is running mxRun step, I only seem to see one R process. When it summarizes results it seems to use 4 (as desired on new Macbook Pro). I had to increase the nReps to some 100,000 to see this behavior. So it looks like

modelResults <- mxRun(topModel, silent=TRUE, suppressWarnings=TRUE)

Uses 1 processor, whereas

results <- t(omxSapply(modelResults@submodels, getStats))

uses 4.

Hi Mike,

That looks like its related to an edit we made to the code last week. I'll look into it and get back to you soon. Thanks!
