Passing input numbers to ECMNet as formulae?
 

Hi all,
I'm doing factoring on some pretty big numbers (all of the form 2^p+1) using ECMNet.
My problem is that if I precalculate the exact integers to test they come to several kilobytes, so I get a network timeout error when trying to connect clients, over the LAN, let alone the Web.
Is it currently possible to pass the inputs as simple/very much shorter "formulae" (I believe this was a feature added to version 6 of GMP-ECM)?
If so, great! please tell me more! If not, might it be on the ECMNet wish-list?
Thanks, in anticipation,
J

You can pass what you want from ECMNet server to the ECMNet client. This includes formulae. You need to ensure that the version of GMP-ECM you are using can support formulae (version 6 does). The only limitation is that the ECMNet server will not verify any factors if the candidate is a formula.

Excellent!
Thanks very much (once again) rogue/Mark.
