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

This adds a bunch of static functions that implement unsigned two's complement bignum arithmetic. They could be used to implement much of APInt, but the idea is they are enough to implement APFloat as well, which the current APInt interface is not suited for.

Hi again, One important correction of my first message: I misinterpreted the output. Actually in that R session 2 input files were processed one after the other in a loop. The first (with 88 parts went fine). The second (with 85 parts) produced the sendMaster errors and failed. If (in a new session via Rscript) I only process the second input file it will work. The other observations on R vs

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,

I'm receiving the following error when trying to repartition and reformat a USB flash drive via parted using a simple script. The bug follows: /sbin/parted -s /dev/sdb mkpart primary fat32 Backtrace has 14 calls on stack: 14: /usr/lib/libparted-1.8.so.0(ped_assert+0x3b) [0x10af3b] 13: /usr/lib/libparted-1.8.so.0 [0x146194] 12: /usr/lib/libparted-1.8.so.0 [0x146f4d] 11: /usr/lib/lib...

Hi Tomas, Thanks for your prompt reply and your offer to help. I might need to get back to this since I am not too experienced in debugging these kinds of issues. Anyway, I gave it a try and I think I have found the immediate cause: I installed the debug symbols (r-base-core-dbg), placed https://github.com/wch/r-source/blob/tags/R-3-5-2/src/library/parallel/src/fork.c in cwd and changed the

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

>From the earlier patches - that simple fix for indexes not counting non-data partitions in gpt and mbr cases. Patches don't touch any other parts of the code at this stage - bigger stuff later for disklib as we agreed - but this is potentially useful right now.

I am just getting started with Rails, don''t know any Ruby, and don''t quite even get object oriented programming yet. I have tweaked my schema to The Rails Way and have generated a bit of scaffolding. I am trying to create a new Part, which references a PartName and a PartNumber. I can create a PartNumber on the fly, but the PartName has to exist. I have an inelegant solution

The block counts in the APM partitions assumed 512 bytes per block, whereas the start block numbers assume 2048 as announced in the APM header. This change divides the affected block counts by 4 to correct the assumption. --- utils/isohybrid.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/utils/isohybrid.c b/utils/isohybrid.c index c5b4281..7d0864e 100644 ---

Hi all, With the help of Tomas, I was able to track the issue down: Prior to R v3.6.0 the parallel package passes an uninitialized variable as the file descriptor argument to the close system call. In my particular R session this uninitialized variable (reproducibly) was holding the value 7, which corresponded to the file descriptor of the write end of the pipe the second child would use to

Dear R-Core Team, I found an unexpected behaviour in utils::removeSource (also present in r-devel as of today). --- # create a function which accepts NULL argument foo <- function(x, y) { if (is.null(y)) y <- "default foo" attr(x, "foo") <- y x } # create a function which utilizes 'foo' testSrc <- function() { x <- 1:3 x <- foo(x,

EFI systems typically don't support booting off ISO 9660 filesystems, even if written to USB sticks. This patch adds support for generating a GPT that covers the stick as well, with an additional partition entry pointing purely at the secondary El Torito image. When burned to CD the secondary El Torito will be used as an EFI boot image, and when written to a USB stick the GPT partition

I have the following: @lot = Lot.find(params[:id]) part_nums = Part.all(:conditions => ["id <> ?", @lot.part.id]) I guess I should mention that Lot :belongs_to => :part I was looking at the log following the execution of these two statements and I saw something like this: Lot Load (0.4ms) SELECT * FROM "lots" WHERE ("lots"."id" = 13) Part

1) At the end of main, there's attempt to free cur_part->record, which rarely comes from malloc. Only valid case is if gpt handover was performed and chaining was not successful (cur_part->record is overwritten with gpt specifc handover record). Freeing the handover area has been adjusted. 2) If our current iterator is ebr, parent wouldn't be freed at the end of main. Added generic

Hi, following will be 6 patch proposals for isohybrid.c 1: Encode GPT partition names as UTF-16LE 2: Correct blocking factor in APM partition block counts 3: Correct end block address of first GPT partition 4: Write GPT backup to the very end of the image 5: Change all fseek(3) to fseeko(3) 6: Introduce option --mbr and make isohybrid.c compilable standalone If the form needs adjustments,
