Something I just realised that I neglected to mention in my example was that I need to apply CPU affinity in the script. That is, I need to be able to specify that 'worker 1' MUST use CPU0, 'worker 2' MUST use CPU1, etc.

This is because I need to have another parallel code block where each worker launches an external single-threaded executable that will be accessing another DB and writing results to a third DB but these MUST NOT access and write to the same table at the same time. This affinity is in essence to avoid access conflicts/violations.

How can this be done in MCE?

Thanks again.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
