[LLVMdev] LLVM memory management
...t is the component called lli which is part of the LLVM compiler infrastructure. The command lli allow for programs compiled to bytecode to be run directly. 1. How does the lli keep itself from being overwritten by a misbehaving program? 3. does it support multithreading? 4. does lli allow for multitasking or do you just ran one VM per program? 5. if it does support multitasking how does it keep processes from colliding? 6. if it does not support multitasking and runs one VM per process then what means are there for communication of processes? 7. does lli support emulated virtual memory? Thank...

EFI: ipxe + syslinux = Failed to read blocks: 0xC
...uest 6 - iPXE receives the reply 'filename=uri:syslinux.efi' 7 - iPXE loads syslinux.efi from supplied URI 8 - iPXE invokes the downloaded image 9 - from here on, only syslinux is running. Of course, the FW provides the UEFI API for basic disk and network access and so on, but it is not a multitasking system is it? After step 5 I did not expect the ROM FW would do anything with the DHCP responses to requests that were sent by iPXE. I can set the filename to http://<ip:port>/<path>/syslinux.efi and still see the same result. The HP ROM FW can only do tftp, so it must be iPXE t...

question about running multiple R windows
Hello, I use R on a Microsoft Windows machine. Is it possible for me to open multiple windows of R, have them run the same program but for different data sets, and get accurate results? It takes 8+ hours to run the program so I want to multitask as much as possible. Thanks in advance, George Chen

high context switching and high load averages slowing down system
Hi All, I have a HP DL 580 with 4 3 GHz CPUs and 4 GB RAM. I'm running Oracle on it. Throughout the day I am getting high load averages (6 - 18) and at the same time I see context switching go over 300,000. Sometimes over 500,000. This is slowing the system down to a crawl. My OS is RHEL 3 AS Update 4 with the 2.4.21-32.0.1.ELsmp kernel. Any ideas on why this is happening and how to fix

Missing dependency in C6 ISO
Greetings, I had downloaded c6 64 bits ISO, selected all packages to be installed. One dependency warning relating to Emacs appeared. I chose to continue. Unfortunately I was multitasking and did not note down the package name Twice this issue appeared -- first time around aborted install due to power cut. Did anybody else face this situation? Also is there a better way with just DVDs and not LAN to select all package install. (no Kickstart, NFS server etc.) I have the ISO ima...

Number of worker processes on hyperthreaded processor
Good morning, The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server. In the case of hyper-threading, should this be the number of cores or the number of threads? For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads. Would I start my worker_processes at 4 or 8? Finally, would the same apply to Nginx worker processes? Many

Question about R and multiple CPU's
...er "things" going on with most modern systems such as operating system and other processes that in practice affect this observation a bit. In addition if I had a R environment where multiple people were logging in and running R queries that would likely gain from multiple CPU's and a multitasking OS I'm assuming. I'm just trying to get a feeling and validate what I think I am seeing. Thoughts and comments are appreciated. Thanks, Anthony [[alternative HTML version deleted]]

Re: Programming ...
...makes these even more likely to succeed than they appear at first. Linux is not one of those "older Unices". ---------------------------------------------" To handle this, you must put in a lot of thought. Generally, a file operation is a serial resource that is being used in a multitasking environment. The traditional ways to deal with serial resources are 1) use gatekeepers to enforce serial access to a serial resource, and 2) lock the system down so that you own all of the cpu cycles until completion of your operation on a serial resource, or 3) don't use the serial resourc...

Any way to boot Windows NT (specifically Win2K) directly?
I decided to install Win2K on my "retrogaming/htpc" system to take advantage of the dual processors in the thing when I'm multitasking a lot, but, it's kind of annoying having to use first one bootloader to chainload my Windows 98 partition, then, via NTLDR, selection Windows 2000 to get to Win2k. I tried using the recovery console to try to force it to write a boot sector to that partition, then chainloading it, but, the...

Is log_in_vain really good or really bad?
Heya.. Yesterday someone "attacked" by box by connection to several ports.. In other words, a simple portscan.. yet, since my box has "log_in_vain" enabled, so it tries to log everything to /var/log/messages, since the logfile got full and the size went over 100K, it tried to rotate the log to save diskspace.

This problem is specially important in two environments : - When you have a limited resources, as occurs in the mobile phones, pads , tablets... - When the programs must run continuously in a multitask environment *c) You can use with any allocator if it is according with the STL definition*. The suballocator provides speed and memory management to any allocator d) In the insertion in a std::set, the allocation time is around 1%. The suballocator obtain time reductions over the 30% respect the...

running R command in the background
Is there a way to call an R function to work in the background within the same R session? What I have in mind is the equivalent of adding '&' at the end of a UNIX command, so that R can process an intensive command while I execute other R commands. I want to do this in the same R session, rather than with multiple calls to R, so that all my modified objects will stay in the same
