Hi Valerie,
I have re-run my two examples twice using "log = TRUE" and updated the
output at http://lcolladotor.github.io/SnowParam-memory/ As I was
writing this email (all morning...), I made a 4th run where I save the
gc() information to compare against R 3.1.x That fourth run kind of
debunked w

Was the problem during build or check where a man page example or unit

Hi Leo,
Thanks for the sample code I'll take a look.
You're right, SnowParam has changed quite at bit - logging, error
handling etc. The memory use you're seeing is a concern - thanks for
reporting it.
As an fyi, the log output for SnowParam and MulticoreParam now includes
gc(), system.time
Hi,
I ran my example code with SerialParam() which had a negligible 4%
memory increase between R 3.2.x and 3.1.x This 4% could very well
fluctuate a little bit and might be non significantly different from 0
if I run the test more times.
I also added a second example using code based on my analys

in gQTLstats. I substituted the foreach abstractions and the code
worked. I still
have difficulty seeing how to diagnose the trouble I ran into.
I'd suggest that you code so that you can easily substitute parallel
Hi,
I have a script that at some point generates a list of DataFrame
objects which are rather large matrices. I then feed this list to
BiocParallel::bplapply() and process them.
Previously, I noticed that in our SGE managed cluster using
MulticoreParam() lead to 5 to 8 times higher memory usage a
