Re: [Bioc-devel] Redirect workers output to STDERR, how to do so with current BiocParallel::SnowParam()?
Hi Valerie, I added a short explanation to http://lcolladotor.github.io/SnowParam-memory/ about how the files are linked (see commit https://github.com/lcolladotor/SnowParam-memory/commit/602e42dd60e4a988425bf41b774263c058a7551a). The entry you selected, https://github.com/lcolladotor/SnowParam-memory/blob/gh-pages/mem_emails/snow-3.2.x.txt#L27-L38, is linked to the stderr log file https://github.com/lcolladotor/SnowParam-memory/blob/gh-pages/logs/snow-3.2.x.e6463239 and stdout log file https://github.com/lcolladotor/SnowParam-memory/blob/gh-pages/logs/snow-3.2.x.o6463239 The key is the job id, which is on the first line of each entry in the emails from the cluster and is used at the end of the names for the log files. And yes, like you figured out, the Max vmem line (https://github.com/lcolladotor/SnowParam-memory/blob/gh-pages/mem_emails/snow-3.2.x.txt#L37) is the maximum memory used as reported by my cluster. It's normally in GB, but could be in MB as in https://github.com/lcolladotor/SnowParam-memory/blob/gh-pages/mem_emails/der-serial-3.1.x.txt#L11 Cheers, Leo On Tue, Jul 14, 2015 at 3:12 PM, Valerie Obenchain voben...@fredhutch.org wrote: Hi, Thanks for sending the updated information.

It would be great if you had a chance to try any of these out - I'd be

Digging at the code, I see that in SnowParam() the ... argument is
saved in .clusterargs
args - c(list(spec = workers, type = type), list(...))
.clusterargs - lapply(args, force)
However, ... is still passed to .SnowParam(), and .SnowParam() fields are:
fields=list(
cluster=cluster,
.clusterargs=list,
.controlled=logical,
log=logical,
threshold=ANY,
logdir=character,
resultdir=character)
So, I'm wondering if ... should not be passed to .SnowParam().
## Trying to pass outfile to .clusterargs directly doesn't work
## Actually, I'm surprised it didn't crash .SnowParam()
x - bplapply(1:2, print, BPPARAM = SnowParam(workers = 1,
