Eclipse, MPICH and PTP for the administrator. Custom bundle for working with the cluster

If the blog isn't suitable, tell me where you can transfer

For the programming "under the cluster" there are a lot of technologies, which includes such giants as the commercial Visual Studio in version 2010 which programmers Microsoft was undertaken a gigantic work, and the open-source Eclipse, which will be discussed.

So, for Eclipse, the development team is actively developing a bunch of PTP & PLDT, all information about which can be found on the website.
Notes for those interested:
* Reviewed compilation of project C. Project C is configured similarly. For Java not tested.
* Administrator guide.

In short, to jabracada:
* Eclipse needs to be properly assembled with the required plugin (PTP & PLDT);
* must be collected by the implementation of the MPI (in this case, MPICH, but you can use OpenMPI);
* MPICH will run your daemon on the compute nodes (including the head)


So, first collect the necessary. We will be working in Linux.
You must share via NFS place and run MPICH on all nodes. This is because MPICH needs to run your daemon on all nodes.

wget www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/1.2.1p1/mpich2-1.2.1p1.tar.gz
tar xvf mpich2-1.2.1p1.tar.gz
cd mpich2-1.1.1p1
./configure --prefix=/home/mpich
make
make install

Download Eclipse eclipse.org in this case, Eclipse Galileo. Unpack in any place and run.

Eclipse to work with the cluster uses Parallel Tools Platform (PTP) + Parallel Language Development Tool (PLDT). We install using Help- > Install New Software.

Update site for PTP: download.eclipse.org/tools/ptp/releases/galileo

Select the required option (and necessary at this stage only the PTP PLDT and Support For MPICH2) and install the plugin. To finish the setup of the plugin you need to install native debugger, and make:

cd /distr/soft/eclipse/plugins/org.eclipse.ptp.linux.x86_64_3.0.1.201002011019
sh BUILD

If the debugger was installed (there was a bin subdirectory), then proceed to the next step — configuring MPICH2.

Create a file .mpd.conf and put in it the secret word for the organization "ring" the demons of MPICH2, which will be used by the demon with nodes to connect to the daemon on the head node
touch /etc/mpd.conf
Enter the word: MPD_SECRETWORD=someword
chmod 0700 /etc/mpd.conf
/home/mpich/bin/mpd-n --daemon
/home/mpich/bin/mpdtrace -l
By using mpdtrace get the port number on which "hung" our demon. We are going to use for the formation of "rings" MPICH2.
Crucify the file with the secret word on all nodes:
for i in `seq 1 []`; do scp /etc/.mpd.conf [name]$i:/etc/; done;
Start the daemons:
/home/mpich/bin/mpd -h sblade -p [the port on which showed mpdtrace] --daemon

Will check on the head node, how was the setup:

sblade:~# /home/mpich/bin/mpdtrace -l 255/pts/5 [17:27:11]
sblade_44222 (192.168.101.101)
node2_33135 (192.168.101.2)
node3_43780 (192.168.101.3)
node1_36588 (192.168.101.1)

If so, then configuring Eclipse and PTP MPICH over. Administrator.

ODBC Firebird, Postgresql, executing queries in Powershell

Изображение
Sometimes, system engineers may need to obtain specific data directly from the DBMS by means of Powershell. In this article I want to demonstrate two methods of operating firebird, postgresql through the odbc driver and client library. let's Start with the firebird and work with the database through the ODBC driver, you first need to register in the system client library GDS32.DLL, its bit width should be the same as the ODBC driver which should be installed next, download on the manufacturer's website , be sure during installation you need to tick on the registration of the library. Next install itself ODBC, who also take on the manufacturer's website , do not forget that the bit size should match the bit count of a previously installed client. Now actually have a powershell script, it was based on example in C# for postgresql. the $dbServerName = "localhost:base.gdb" $dbUser = "SYSDBA" $dbPass = "masterkey" [string]$s

garage48 for the first time in Kiev!

Изображение
this weekend, Kiev will host a very cool event Garage48 — the idea is that for two days to create a startup. In the “create “ includes everything needed to present your business idea, qualify, technically, to bring it to life, and then be able to sell it to strict spectator and wise mentors. This event was invented in Estonia and has already managed to visit many countries of the world. Finally, Garage 48 has reached the Ukraine: from 11th to 13th may we occupy the Library of KPI , which is located on the Avenue Victory 37 and start enjoying foreign mentors (they will guide you in the right direction to create a startup and guide you on the right path, if you go into the jungle), as well as the company of their colleagues and event organizers — representatives of Garage48 Foundation And IT DOU-activist Vicky Zorbas. On Friday we will get acquainted with the ideas of the participants, will select the best ideas and form teams. Saturday morning will see which team surv

The Ministry of communications wants to ban phones without GLONASS

Today in the Ministry of communications submitted the bill , according to which in Russia it will be possible to use only those mobile phones that include support for the GLONASS navigation system. Although it is not clear how this will be monitored, most likely, we are talking about banning the importation and sale. This decision was taken in order, and I quote in order to ensure the stability of the unified telecommunication network of the Russian Federation in various conditions. Requirements (in the case of the adoption of this act) will apply to manufacturers and sellers. To monitor the implementation of law be entrusted to Roskomnadzor. How has this come? For me personally this news is not very surprising (and not only because this is another project state silly the Duma), not so long ago there was another similar initiative, the essence of which was to translate public transport to use the system "To the end of the year practically the whole of Moscow is covered
