Utils in HepLib

There are several useful utils installed to the directory <INSTALL PATH>/bin.

heplib++ - HepLib g++

The basic uage:

heplib++ -o prog prog.cpp

The content in this script

g++  -I'<INSTALL PATH>/include' -Wl,-rpath,. -Wl,-rpath,'<INSTALL PATH>/lib' -L'<INSTALL PATH>/lib' -lHepLib -lcln -lginac -lMinuit2 -lcubaq -lqhullstatic -lquadmath $@ -lHepLib -lcln -lginac -lMinuit2 -lcubaq -lqhullstatic -lquadmath

heplib-config - parameters

Genernal information of heplib-config from heplib-config --help

Usage: heplib-config [--prefix|--cflags|--ldflags|--help]

• heplib-config --prefix to get the <INSTALL PATH>

• heplib-config --cflags to get the -I’<INSTALL PATH>/include’

• heplib-config --ldflags to get the -Wl,-rpath,. -Wl,-rpath,’<INSTALL PATH>/lib’ -L’<INSTALL PATH>/lib’

sc - Server / Clients

Genernal information of sc from sc --help

A simple Server/Client, bypass with [i].log
Supported Options:
  --total: total elements @server.
  --port: server port @server/@client.
  --server: server ip or hostname @client.
  --command: command with [i] replaced @client.
  --round: round to be cycled @server.

One can run the following command on the master node

sc --total 100 --port 1234

One will get the message as follows:

Started @ 2020-11-17 16:05:27
  Server Port: 1234
  Server: 0 / 99 @ 16:05:2

The server is ready to dispatch item (from 0 to 99) to the connected slave node.

Now one can run the following command on each slave node

sc --server master-node-host --port 1234 --command "echo [i]"

one will see the slave node will repleatly get the item from the server, and exceute the command echo [i], note that [i] will replaced by the actual index (form 0 to 99).

Note that to prevent the command to run multiple times on the same [i], one can generate a [i].log from the command, e.g.,

sc --server master-node-host --port 1234 --command "echo [i] > [i].log"

sc will skip the item [i] when there is a file named [i].log.
