Hello,

I am trying to parallelize the output of my Maple18 program, such that it is able to write into multiple smaller output files at the same time, rather than into one unique big file spending much time in this operation...

This is the code:

As you can see from the code, I have tried with different combinations of options. The errors that I get are:

-----------------------------------------

(only one file: "rows-1 < 10000")

Option1A = Error, (in fprintf) string expected for string format

Option1B = Error, (in unspecified) Too many levels of recursion for display

Option2A = OK (but there isn't parallelism here....)

Option2B = OK (but there isn't parallelism here....)

--------

(more than one file: "rows-1 > 10000") 

Option1A = Error, (in fprintf) string expected for string format

Option1B = Error, (in unspecified) Too many levels of recursion for display

Option2A = Error, (in StringTools:-Split) first argument must be a string

Option2B = Error, (in StringTools:-Split) first argument must be a string

-----------------------------------------

Instead, if I simplify the definition of D_vol to one single sum (for exemple 2+2), this is what I get:

-----------------------------------------

(only one file: "rows-1 < 10000")

Option1A = OK (but there isn't parallelism here, and the example is trivial 2+2=4)

Option1B = OK (but there isn't parallelism here, and the example is trivial 2+2=4)

Option2A = OK (but there isn't parallelism here, and the example is trivial 2+2=4)

Option2B = OK (but there isn't parallelism here, and the example is trivial 2+2=4)

--------

(more than one file: "rows-1 > 10000") 

Option1A = OK (but the example is trivial 2+2=4)

Option1B = OK (but the example is trivial 2+2=4)

Option2A = Error, (in StringTools:-Split) first argument must be a string

Option2B = Error, (in StringTools:-Split) first argument must be a string

-----------------------------------------

Can you please help me? Any advice wil be really useful....

Thanks
