How to use mpi.allreduce() in Rmpi?
Hi everybody! I have the next code which makes a reduction of the *a *variable in two slaves, using the Rmpi package. library(Rmpi) mpi.spawn.Rslaves(nslaves=2) reduc<-function(){ a<-mpi.comm.rank()+2 mpi.reduce(a,type=2, op="prod") return(paste("a=",a)) } mpi.bcast.Robj2slave(reduc) mpi.remote.exec(reduc()) cat("Product: ")

Are there any tools to reduce the IR file that caused a problem?
Hi everyone, I want to test the passes in llvm, and I got some passes sequences that caused the crash of opt. Although I can use bugpoint to narrow down the source of problems, I can only get some reduced and simplified IR and passes to reproduce the problem. My question is how to get the reduced IR of the original IR file to reproduce the problem. For example, "opt a.bc -a -b -c -d (where a, b, c and d are passes)" has a crash problem caused by "-a -b -c -d", so we can use bug...

gluster map/reduce performance..
Hi, all, i try to check the performance of Map/Reduce of Gluster File system. Mapper side speed is quite good and it is sometimes faster than hadoop''s map job. But in the Reduce Side job is much slower than hadoop. i analyze the result and i found the primary reason of slow speed is bad performance in Merging stage. Would you have any suggestion for this issue FYI check

[RFC] Changes to llvm.experimental.vector.reduce intrinsics
Hi all, While working on a patch to improve codegen for fadd reductions on AArch64, I stumbled upon an outstanding issue with the experimental.vector.reduce.fadd/fmul intrinsics where the accumulator argument is ignored when fast-math is set on the intrinsic call. This behaviour is described in the LangRef (https://www.llvm.org/docs/LangRef.html#id1905) and is mentioned in

Need help with reduced row echelon form
Hello I have a 3x3 matrix (A), which I would have to reduce to Reduced Row echelon form.  Besides, at every iteration k, the elementary row matrix Ek has to be printed and also print the product of sum Ei (i=1 to k) and A. Any ideas how to go about doing this. KS. [[alternative HTML version deleted]]

Increasing address pool reuse/reducing .o file size in DWARFv5
tl;dr: in DWARFv5, using DW_AT_ranges even when the range is contiguous reduces linked, uncompressed debug_addr size for optimized builds by 93% and reduces total .o file size (with compression and split) by 15%. It does grow .dwo file size a bit - DWARFv5, no compression, not split shows the net effect if all bytes are equal: -O3 clang binary grows by 0.4%, -O0 clang binary shrinks by 0.1% Should

[LLVMdev] Statistics for 'switch' instruction.
Hi all! I collected some statistics for SwitchInst, based on our test-suite. I found that efficiency is meaningful for parser-like applications only, about 15-20% of cases may be reduced (see top 10 items in Raw sheet of attached .xls file). Below some numbers. Total number of cases in all test-suite -- 11835. Clusters possible to make -- 503 Clusters with size (H - L) + 1 >= 8 -- 48 Cases stay single numbers -- 9794 % of all cases may be...

The effects of queueing on delay
I have a router with 3 network interfaces like in the following ASCII diagram below. All interfaces are 100mbit. There is tcp traffic being sent from net1 to net3 and from net2 to net3 and the tcp connections consume as much bandwidth as possible. There is a pfifo queue on the egress interface eth0 of the core router with a limit of 10 packets. net1 --> (eth1) router (eth0) -> net3

[LLVMdev] Reducing the size of LLVM and clang
Hi all, We are looking to try and reduce the size of the clang and LLVM libraries and were wondering if anyone had any advice on how to do this. All we want is to be able to compile from a single language to a single back-end and for that back-end to emit instructions; we don't care about anything else. Currently we are building LLVM to use only our target, so that is OK. Is it possible to

how can I reduce binary size of sshd?
Hi Guys I need to implement ssh server daemon on OLD installations of real time OS, which uses flash memory and every program gets loaded in flash mem, once the device is booted. I have very limited space in flash memory of this device. SO what we are trying to do is reducing the size of sshd by taking out least common used things. Can someone give me input what features, version and crypto

OT: Photo Editor to reduce 272 photos to VGA at once
I returned from Bogot? and have a Folder with 272 photos that total 419.9 MB. I would like to email them to several people who were there for the concerts I attended. I have Picasa, gThumb (not really an Editor but I believe it can reduce the quality of photos) and The GIMP installed. Is there a way I can have a photo editor reduce all of them to VGA size, without doing that 272 times? The people

matrix row product and cumulative product
I spent a lot of time searching and came up empty handed on the following query. Is there an equivalent to rowSums that does product or cumulative product and avoids use of apply or looping? I found a rowProd in a package but it was a convenience function for apply. As part of a likelihood calculation called from optim, I?m computing products and cumulative products of rows of matrices with

Reducing RAM requirement of sshd
Hi All, I have ported OpenSSH on an embedded uClinux platform. My main concern is that sshd takes 1 MB if RAM while its in running state and for each incoming connection it eats up 1 mb ram again. I am looking for help in reducing RAM requirement for ssh daemon. Any comments ? Thanks in advance, Reema.
