| 2 | I suspect that your remaining problem with F90 was fixed in r4896 (missing<br> eval in <a href="http://configure.in">configure.in</a>). Would you be willing to try two more things?<br><br> 1. Run {{{file /home/user/mpich2-install/lib/*}}} and send us the output.<br> |
|---|
| 3 | This should hopefully confirm my theory that you are getting a 64-bit f90<br> library despite trying to build it as 32-bit. Please also send your<br> config.log.<br> 2. Try building the following tarball instead of mpich2-1.1. It should<br> |

| 5 | <br> -Dave<br></blockquote></div><br>I'm sorry, I misinformed you a little in my previous letter. I retried to install mpich2 under 64-bit OS with commands -m32 and -m64 (CC/CXX/F77/F90 I wrote with small letters):<br> |
|---|
| 6 | >...configure cc="gcc -m32" cxx="g++ -m32" f77="gfortran -m32" f90="gfortran -m32" gfortran="gfortran -m32" -prefix=...<br>and<br>>...configure cc="gcc -m64" cxx="g++ -m64" f77="gfortran -m64" f90="gfortran -m64" gfortran="gfortran -m64" -prefix=...<br> |
|---|
| 7 | And then I compiled my program in each case. It was everything without problems (in my previous letter it was my mistake by installation of mpich2). After that I checked the time during a multiprocess calculation in both cases. So under 64-bit OS both by installation with -m32 and with -m64 the same calculation lasts ~9 min. Under 32-bit OS it lasts ~8 min.<br> |

| 8 | The multiprocess calculation with mpich2-trunk-r4938 I test today under 64-OS and tomorrow I report results.<br><br>Alexej Mazheika<br> |
