Dear list,
I observed two problems that I suppose are generic.
First, using 'Rprof' to profile a parallel (based on the package
'parallel') code caused
.... Error in unserialize(node$con) : error reading from connection....
Second, on a multicore desktop, I concurrently opened two terminals
and ran two separate R sessions, both running (actually
identical) parallel code (which sets up a cluster with as many nodes
as there are cores). I got
?...Error in socketConnection("localhost", port = port, server = TRUE,
blocking = TRUE, ?: ? cannot open the connection
In addition: Warning message:
In socketConnection("localhost", port = port, server = TRUE, blocking = TRUE, ?:
?port 10187 cannot be opened
Are there ways to do the two things above without problems?
Thanks!
Zepu
