similar to: dtrace : isolating the slow write

In order to get more information on IO performance problems I created the script below: #!/usr/sbin/dtrace -s #pragma D option flowindent syscall::*write*:entry /pid == $1 && guard++ == 0/ { self -> ts = timestamp; self->traceme = 1; printf("fd: %d", arg0); } fbt::: /self->traceme/ { /* elapsd =timestamp - self -> ts; printf("

Hi, Earlier this year I "upgraded" from wine 20010510 to 20011226 in order to see if some kind of resource leak was fixed which caused screen redraws to get progressively slower and slower and slower and slower, .... That was fixed but there seemed to be a significant number of graphics and UI regressions. I've just upgraded to 20020228 to see if things were any better and within

Hi llvmer, I am trying to learn how to use llvm. My question is described as the following, there has already a testcase code, and I get bytecode by using llvmgcc. What I want to do is to insert a call funcation into each basic block, which is for statistic some information. 1) I implement call function in another c/cpp file and can I insert the external call function to existed bytecode ? if it

Hi, Thank Brian Gaeke so much. Following TraceBasicBlocks.cpp, I modified the code as below and could insert instruction or function I need into anywhere in Module. But it works well without BB->getInstList().push_back(InstrCall), and if I add the BB->getInstList().push_back() following new CallInst(), I got error information when runing opt. What is the reason for it? And is it necessary

I recommend that you look at the various pieces of code under llvm/lib/Transforms/Instrumentation, e.g. BlockProfiling.cpp and TraceBasicBlocks.cpp. They do essentially the same thing as you are trying to do. > 1) I implement call function in another c/cpp file and >

I''m trying to profile the time spent in libc functions in a large build job (building Perl), and I have trouble getting ufunc and func working. (func() is not strictly needed; I was just hoping to use it in order to profile idle time.) Here''s the story. I''ve written a dtrace script to start a separate dtrace process for each invoked command: int fileid;

I''m trying to isolate some Rails apps I will be running on a shared server; by isolate I mean I want the application to be unable to access any of the filesystem below its root. These apps are from a few different people and I don''t want them to accidentally (or purposefully) blow someone else''s files away. I would just create a unique user for all of them, but I

Dear all, I am trying to calculate the mean of one column for many data frames. The code I am using is as follows: > for (i in seq(nrow(index))) { ??? ??? assign(paste(model, "_mean_",index$year[i], index$month[i], sep=''), ????????????? mean(get(paste(model, index$year[i], index$month[i], "[,3]", sep='')))) ???????? } Error in get(paste(model,

Hi All, I am looking to utilize gluster on amazon aws for shared storage among web servers (Elastic Beanstalk). However, since I plan on using the gluster tier for numerous different beanstalk environments, I'd like to isolate the systems from accessing each others data. Since Beanstalk uses dynamic IP addresses, I can't utilize the built in auth.allow and auth.reject in gluster to

And we'll take a look at Pf & IPTables :) Good evening! >> There is no centralized way to remove a subnet or block a user.

We started to take a look about that, and apparently, it seems that the IP in the public key is taken into account when a client connects to a gateway. Spoofing at that level doesn't seem easy, because the IP address seems to be part of the authentication process. Dealing with inside threats seems however a good feature for future versions ;) Le 04/05/2015 21:50, Etienne Dechamps a ?crit

Hi guys, I'm planning a fileserver for around 12 small companies (two to five people each) who share one buidling/office and all IT resources. Since I'm not responsible or involved in the client support, I want to prevent the different companies from seeing each other's PCs through network browsing, for example, company A consists of Joe, Mary and Pete, and Company B consists of

Hi all, What I'd like to do is to is to be able to extract a string corresponding to only the file name from a string containing the complete path, i.e. from the following path string: "/Users/ken/Desktop/test/runs/file1" I would like to end up with: "file1" This would be most ideally done in a platform-independent way. Thanks in advance, -Ken

Dear R-gurus, I know that it is not a R problem, but as need to implement some solution for this on R, I would like to know if someone help me on how to isolate X on the expression below. K=(sen A * sen B ) + ( cos A * cos B * cos ( X - Y ) ) Any help are welcome mitinho astronauta brazil [[alternative HTML version deleted]]

Hi! I'm setting up a VPN with friends of mine, and we are currently considering the possibility to opening the subnet to more people. Considering that one day or another we may have to isolate a subnet (because of bad behaviour, or because it has been compromised), which solution(s) would you recommend for such a situation?

As so far I have 15 servers feeding data to my four node Gluster-FS (cluster), at this current time all of my scripts are faceted to mount the volume and move data into its directory, only issue I see with this is that half of these clients should not be able to go one level back from its 'home' directory when transfering data - I wanted to see if there was a way to isolate these specified
