The remote machine will not have any direct access to the files on the local
machine. So avoid the route of having the remote machine send it's output
to a file.
There's no need to copy and paste text from the originating notebook though.
Note that the ParallelTable returns a list. Record that result, then write
it out to a file, like this:
allresults = ParallelTable[
{
start = AbsoluteTime[];
res = NIntegrate[
int = dsigmapdf[theta, 14000^2, a Pi/10, 11], {theta, 0, Pi}];
Print[a, " : ", N[AbsoluteTime[] - start, 4], " seconds . . . ",
int];
{a Pi/10, res} (* this is the return value of one calc'n*)
}
, {a, 0, 4}
]
(*now write "allresults" to an output file*)
(*Probably more convenient to write each result independently, like this:*)
PutAppend[#, "xsection.txt"] & /@ allresults
