Hi Josh, Let me try val tmp = new Array[Rail[Byte]](Nb*(Nr+1), (i:Int) => new Array[Byte](4));
and experiement Array2D with Rail[Rail], worth to put on my report :), but the problem is sometime i need to a row from a matrix to feed it to another function. Current x10 doesn't do this, additional operation will cause more time like mapping a row from 2D region to a Rail I compiled using Java-backend 'x10c' (hit some error using x10c++ ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ X10-users mailing list X10-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/x10-users
