Hi, I am using rsync-2.5.5 on power pc system. It is an embedded system with very low memory few MBs. Most of the time only 4-5 MB memory is free (as shown using free command). I have an application that periodically (every 20 sec) fires rsync command from system command i.e. system ("rsync..") to a remote m/c connected to it. The data I have to rsync has hardly 60 files with total size

Hi, I have a setup where I wish to transfer around 100 files from embedded device to a connected PC. The embedded system at anytime contains 20MB free RAM. However, on running rsync periodically (20s interval), OUT OF MEMORY error results after few minutes, say 30 minutes killing this application and other application softwares running on the embedded device. rsync version is 2.6.9 and rsync

Hi, What is the behaviour of rsync on receiving SIGUSER1 signal? Can I block it in someway so that my application that repeatedly calls rsync and rsync itself will run smoothly. Regards, Preeti -------------- next part -------------- HTML attachment scrubbed and removed

Hi, I've been doing some tests using serialize() to a raw vector: df <- data.frame(runif(50e6,1,10)) ser <- serialize(df,NULL) In this example the data frame and the serialized raw vector occupy ~400MB each, for a total of ~800M. However the memory peak during serialize() is ~1.2GB: $ cat /proc/15155/status |grep Vm ... VmHWM: 1207792 kB VmRSS: 817272 kB We work with very

Jorge, what you propose is not possible because the size of the output is unknown, that's why a dynamically growing PStream buffer is used - it cannot be pre-allocated.

In principle, yes (that's what Rserve serialization does), but AFAIR we don't have the infrastructure in place for that. But then you may as well serialize to a connection instead. To be honest I don't see why you would serialize anything big to a vector - you can't really do anything useful with that ... (what you couldn't do with the streaming version). Sent from my iPhone

Presumably one could stream over the data twice, the first to get the size, without storing the data. Slower but more memory efficient, unless I'm missing something.

Hello any R user, Working on R 1.8.1 or R 1.9 on Windows, 256 Mb RAM. I am trying to debug/correct/speedup the execution of one of our student's program. Basically, we perform simulations. R is launched with high memory-limits. One execution of the program requires nearly 200 Mbs and is OK the first time. Then, launching it again does strange things: seen from Windows manager, the RAM

Hello, I am trying to plot selected data points to a preexisting persp plot that satisfies a condition. I used the following statement - text(coords[,1], coords[,2], names(act[which(act > 8.75)]), cex=0.7) But I get all the points labeled, instead of the points that satisfy the condition specified. Is there any way to plot only the points I want? Also can this be done using

I've installed successfully LEGO LOGO, a game made by LEGO Media. But, when I run it, I get a messagebox with the following error: ?LEGO LOCO only runs in High Colour (16-bit) 800x600, 1024x768 and 1280x1024. Please change to one of these settings.? Is there any workaround for this? Or must I change xorg.conf? (I'm using 1024x768. I suppose the problem is depth - mine is perhaps 24.)

Could i get an example to make a binary hard disk image with `mkdiskimage', populate it and install syslinux please? Preferably with a single FAT partition.

Hi, I've been using PxeLinux to boot our Debian kernel successfully for some time now. I recently increased the size of the ramdisk from about 484 MBs to 517 MBs and encountered the following error during bootup: --- RAMDISK: Compressed image found at block 0 Freeing initrd memory: 105519k EXT3-fs: Magic mismatch, very weird! cramfs: wrong magic sh-2021: reiserfs_read_super: can not find

I have been using the read.csv function for a while now without any problems. My files are usually 20-50 MBs and they take up to a minute to import. They have all been under 50,000 rows and under 100 columns. Recently, I tried importing a file of a similar size (which means about the same amount of data), but with ~500,000 columns and ~20 rows. The process is taking forever (~1 hour so far). In

Dear list, when iterating over a set of Rdata files that are loaded, analyzed and then removed from memory again, I experience a *significant* increase in an R process' memory consumption (killing the process eventually). It just seems like removing the object via |rm()| and firing |gc()| do not have any effect, so the memory consumption of each loaded R object cumulates until

Hey Listees, I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3,

Hello, Can somebody recommend CentOS-OK, dual socket motherboards for compute elements? A quick look up at Intel pages suggests they are thinking of them as "server boards", but then they recommend them as "for SMB", I'm somewhat puzzled about it. It would be nice to know what MBs you are using, pros and cons. Thank you in advance -- Eduardo Grosclaude Universidad
