error in parallel:::sendMaster
Hi,
I am facing a very weird problem with parallel::mclapply. I have a script which does some data wrangling on an input dataset in parallel and then writes the results to disk. I have been using this script daily for more than one year always on an EC2 instance launched from the same AMI (no updates installed after launch) and processed thousands of different input data sets successfully. I now

error in parallel:::sendMaster
Hi Andreas,
the error is reported when some child process cannot send results to the
master process, which originates from an error returned by write() -
when write() returns -1 or 0. The logic around the writing has not
changed since R 3.5.2. It should not be related to the printing in the
child, only to returning the value. The problem may be originating from
the execution environment,

mdbox + zlib performing less than just mdbox
I have test environment to determine what would be best settings. I have
been told that enabling zlib compression would be good to save iops on
storage. But doing the test now, I get worse results.

Zimbra benchmarking
Now that I have a working kvm setup, I thought I'd finally try how
Zimbra works. This is mainly some microbenchmarking, so it may not have
much to do with actual performance in real life.
Setup:
- 1GB memory given to kvm (from host's 2GB)
- Intel Core 2 6600 (kvm uses only one CPU)
- CentOS 5
- 15GB qcow2 image on XFS filesystem
- Zimbra 5.0 RC2 RHEL5 x86_64
- Dovecot latest hg,

error in parallel:::sendMaster
Hi Andreas,
thank you very much, good job finding it was EBADF. Now the question is
why the pipe has been closed prematurely; it could be accidentally by R
(a race condition in the cleanup code in fork.c) or possibly by some
other code running in the same process (maybe the R program itself or
some other code it runs). Maybe we can take this off the list and come
back when we know the cause

utils::install.packages with quiet=TRUE fails for source packages on Windows
Hi,
Installing a source package on Windows using utils::install.packages()
with quiet=TRUE fails, while it works with the default quiet = FALSE.
The problem seems to be caused by the fact that when quiet = TRUE,
stdout and stderr are set to FALSE when calling "R CMD INSTALL" with
base::system2() here:

dbmail benchmarking
I thought I'd try benchmarking with dbmail (v2.2.4) to see how much
slower a SQL backend could actually be. Skip to bottom for the
conclusions.
Originally I ran the tests with the databases being in XFS
filesystem. MySQL's performance was horrible. It went 3-7x faster
with ext3.
MySQL 5.0.30 backend (innodb):

The obvious guess would be that Rstudio is attempting something like redirecting output and getting itself confused. However, it is pretty clearly Their Problem, no? Rstudio has their own support infrastructure.

R-alpha: R-0.50-a3: [logical, drop = FALSE] -- bug in R (and S-plus)
This is a bug both in R and S-plus (in R it's "worse"), I think.
Look at this :
ma <- cbind(1,1:8); logi <- rep(c(T,F),4)
ma[logi,]

Dovecot imaptest on RHEL4/GFS1, RHEL6/GFS2, NFS and local storage results
We have done some benchmarking tests using dovecot 2.0.12 to find the best
shared filesystem for hosting many users, here I share with you the results,
notice the bad perfomance of all the shared filesystems against the local
storage.
Is there any specific optimization/tunning on dovecot for use GFS2 on

Benchmarking
I wasted too much time today doing this, but they do show a few
interesting things:
1) mmap_disable=yes is faster than mmap_disable=no. I didn't expect
this. I'm not yet sure why this is, but possibly because then it updates
the mail index by reading the changes from dovecot.index.log, instead of
reopening and re-mmaping dovecot.index. At least that's the biggest
difference between

holding objects in dataframes
Hello list,
I need to keep track of objects that are related to particular
observations. In this case, I need to keep track of polygons that are
associated with observations. What I would ideally have is one column
of a dataframe hold a "polygonal" object (from the spatstat package).
My question: I seem to have managed to do it, but as I haven't read that
