[R] SNOW: Error in socketSelect(socklist) : not a socket connection
I'm trying to use snow in my dual-core (hopefully later this is going to run in a cluster). So, at this moment I create a cluster using SOCK connection (MPI in the future). However when I try to use clusterApplyLB I got "Error in socketSelect(socklist) : not a socket connection". Any ideas ? Do you know if that is going to be an isuue too when I swith from SOCK to MPI ? Sample code is attached. Thanks. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

[R] SNOW: Error in socketSelect(socklist) : not a socket connection
Your R version seems to be out of date. This would happen in older versions of R, prior to 2.8.0 I believe, due to a bug in socketSelect that was fixed last August. luke On Wed, 1 Apr 2009, Ubuntu Diego wrote:> I'm trying to use snow in my dual-core (hopefully later this is going to > run in a cluster).

Possibly Parallel Threads
- socketSelect(..., timeout): non-integer timeouts in (0, 2) (?) equal infinite timeout on Linux - weird
- socketSelect(..., timeout): non-integer timeouts in (0, 2) (?) equal infinite timeout on Linux - weird
- socketSelect(..., timeout): non-integer timeouts in (0, 2) (?) equal infinite timeout on Linux - weird
- socket problems (maybe bugs?)
- using SNOW and clusterApplyLB to run jobs parallel
