What's this page?†

A computer code "pikoe" for proton-induced knock-out reaction calculations for exclusive processes can be downloaded from this page. Some instruction, updates, and FAQ are also available here.

About the program†

Language†

Fortran 90 (complete program).

Notice†

Copyright belongs to the following persons. Please do not redistribute the files or make them public.

• Kazuki Yoshida (ASRC, JAEA)
• Yoshiki Chazono (RIKEN Nishina Center)

If you present or publish results obtained by pikoe, please cite it as follows.

K. Ogata, K. Yoshida, and Y. Chazono, computer program pikoe, arXiv:******.

We have submitted pikoe (a program package and document) to Computer Physics Communications. Once it is accepted/open, we announce it on this page.

Usage†

1. Prepare an input file (a manual and samples are given below) and, if necessary, external file(s).
2. Compile pikoe1.f90
   In some cases, you may need to put an option (see below).
3. Run pikoe1 with redirecting the input file. For example,

   pikoe1 < 12Cp2p11Bgs_set1.cnt

   In some environment, you must type

   ./pikoe1 < ./12Cp2p11Bgs_set1.cnt

Error!†

If pikoe does not run successfully, try the following.

• Read carefully the output. In many cases, the reason for the error is given. Correct your input file and/or external file(s) accordingly.
  • If it is written that the size of an array is not enough, you need to change the parameter(s) given in "module dims" in the source file.
• Put a compiler option that specifies SAVE statement for every local variable and array.
  • gfortran: -fno-automatic
  • ifort: -save (Unix/Linux/OS X) or /Qsave (Windows)
• Make stacksize larger.
  • For example, on the RCNP high-performance computing system, you can put

    ulimit -s unlimited

    in your batch file.
  • If you use Intel compiler on windows, you can add

    /link /stack:***

    when you compile pikoe1.f90 (*** is the stacksize in bytes).
