I am running Perl CGI scripts via the Apache v1.3.28 server in a Unix environment, is there settings that should be taken care of when running command line in this particular case for mpirun (the script alias has already been set up -
ScriptAliasMatch .../cgi-bin/... /usr/users/$1/public_html/cgi-bin/$2) :

The line in Perl script is : 

`/usr/local/apps/mpich/bin/mpirun -machinefile /usr/users/ueug/machine
+s.ALPHA -np 2 /usr/users/ueug/mpiblast/src/mpiblast --config-file=/us
+r/users/ueug/mpiblast/mpiblast.conf -p blastn -d ecoli.nt -i /usr/use
+rs/ueug/public_html/cgi-bin/upload/100seq -o /usr/local/tmp1/d.txt 2>
+ /usr/local/tmp1/err.txt`;

The relevant error is : 

/usr/local/apps/mpich/bin/mpirun: pwd: read error in ..
/usr/local/apps/mpich/bin/mpirun: test: argument expected

Is there anything that should be taken care of when running scripts of this nature? Even when "nobody" user account has been set to a writable directory such that I could execute the command in "nobody"'s account I still could not execute the command via Perl script.

Is it a problem with the server configuration since "nobody"'s account can execute the command?
