similar to: LCG with modulo 2^30

Hello there Can anybody please tell me if there is any package in R to solve the following 4 nonlinear equations with 4 unknowns: alpha*exp(20/sigma)+ beta*exp(21/tau) = 2 alpha*exp(22/sigma)+ beta*exp(9/tau) = 4 alpha*exp(10/sigma)+ beta*exp(30/tau) = 6 alpha*exp(40/sigma)+ beta*exp(39/tau) = 5 where alpha = exp(lambda/sigma) beta= exp(delta/tau) I need to estimate lambda, sigma, delta, tau

Hello, I am following the Agile Rails dev book and I like the command line format used to create example apps in the book. However, I am stuck on one point. How do I run mysql commands from the Rails prompt. I have a Win Xp sys. I can start rails from the command prompt. But if I type "mysql", I get an error saying it is not recognized as an internal or external command. MySQL 5.0.51

Currently we use non-cryptographically secure random numbers in two places, the error filter (to inject errors at random) and the random plugin. For this we have used either random_r or a home-brew-ish Linear Congruential Generator. Use of random_r is problematic on BSDs because it doesn't exist there. Use of the LCG is simply a bad choice. Replace both uses with a better quality and

v2: - Fix seeding. - Add a test that nbdkit-random-plugin is producing something which looks at least somewhat random. Rich.

Hi, I failed to search for R package providing random number generator of "Park and Miller". Anyone know any R package supporting this kind of function? Thanks, Grace -- View this message in context: http://www.nabble.com/Random-Number-Generator-of-Park-and-Miller-tf3636501.html#a10154554 Sent from the R help mailing list archive at Nabble.com.

I am getting "Error: cannot allocate vector of size 197 MB". I know that similar problems were discussed a lot already, but I didn't find any satisfactory answers so far! Details: *** I have XP (32bit) with 4GB ram. At the time when the problem appeared I had 1.5GB of available physical memory. *** I increased R memory limit to 3GB via memory.limit(3000) *** I did gs() and got

I came across this in a simulation I ran under 1.6.0: If I do something like R> x <- rnorm(10) R> rval <- NULL R> for(i in 1:100000) rval <- t.test(x)$p.value then the process size remains at about 14M under 1.5.1, but it seems to be almost linearly growing up to more than 100M under 1.6.0. I know that the above simulation is nonsense, but it was the simplest I could come up

Hello, I was wondering if anybody could help me to find swing modulo scheduling implementation in LLVM. It looks like that SMS has been implemented for SPARC V9 back end but I could not find it anywhere!!

Hi Joerg, I can see the error, and it's just a bad selection of choices. I was wrong in assuming that the "eabi" at the end would always force it: $ clang -target arm-elf-eabi -S mod.c -o - |

Hi all, Sorry for bothering those not interested. I found that ARM backend will insert a modulo function (like __modsi3) instead of the modulo instruction. I wonder how we can inline the modulo function into the program. Is there any OPTION we can use in the opt or llc?

Hi, Timo Sirainen wrote (May 19, 2010 1:50:34 am) : "When a connection from a newly seen user arrives, it gets assigned to a mail server according to a function: host = vhosts[ md5(username) mod vhosts_count ]" This hash function is it still used as it is without modification ? My another question sounds pretty innocent but I have doubts about vhosts_count. Taking two directors

Hi Joerg, > At the moment, this will call __modsi3 and __umodsi3, even though those > functions are not part of AAPCS. Should this be considered a lowering > bug in the ARM target? LLVM actually supports both variants, depending on the target. The __aeabi_* functions are part of the ARM "runtime ABI" and largely independent of AAPCS. For whatever reason, Linux (& Darwin)
