linux - installing mpich2 always installs me mpich -

-

i have mpif90 mpich version 3.0.4, want remove , install mpich2. there problem dislin library, need mpich2.

while on debian distro sudo apt-get install mpich2 installs me mpif90 mpich2 version 1.4.1 (it right 1 need), if run (on ubuntu have mpich version 3.0.4) sudo apt-get remove libmpich10 libmpich-dev , sudo apt-get install mpich2 still installs mpif90 mpich version 3.0.4

how can do?

update 1

thanks. if try install dpkg -i mpich2_1.4.1-1ubuntu1_amd64.deb first have remove previous version 3.0.4, because in conflict.

i remove it, try install 1.4.1 there unsolved dependencies (libmpich2-3 -1.4.1 not installable, libcr0 not installed, libhwloc4, hwloc-nox). suggested run apt-get -f install installs 3.0.4 on debian works fine, 64 bit, wheezy release. on ubuntu 14.04, 64 bit, doesn't work.

you asking how can downgrade vendor-packaged mpich-3.0.4 mpich2-1.4.1

debian , ubuntu make upgrading easy. downgrading little tricky , might require pinning package, rebuilding old .deb newer platform, or can build mpich2-1.4.1 source.

debian: https://packages.debian.org/wheezy/mpich2

ubuntu: http://packages.ubuntu.com/precise/mpich2

source: http://www.mpich.org/static/downloads/1.4.1/

a word of caution: if ask mpich2-1.4, first thing going hear "wow, 2 years old. can try latest version?"

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
