[Comphep-common] Events to produce of LHAEF format

[Ijaz Ahmed]

Dear Lev,

I finally produced a small sample of W+2jets, just 100 events and worked fine and now problem is that how can i generate 100K events,which looks very much time consuming. I have to terminate my GUI, because it took more than 4 days, but still it was running and dont know how long still it take to complete.
Please can you tell me solution that how can i generate big sample in short time (1 day OR 2 days) using only one machine. Please let me know
thanks
Ijaz

      Dear Ijaz,
  You can follow standard instructions how to generate events in CompHEP
(tutorials, publications, manual). Please, start from the simple process
and get the result, then increase the complexity.
   NNPDF is not implemented as internal structure function in CompHEP
and you need to use standard interface to LHAPDF package where this
function has implemented.
      Best regards,
         Lev

In W+,j3,j3 channel, there are many subprocess and to compile them it takes a long time. what is short way, i have only one machine to do that.

I do produce process.dat from GUI. but still wanat to start Numerical calculation, but symbolic calculation is not going to complete, specially from GUI, c-compile is completed with error.
