Hi all, Thought you might be interested: I've released a development version of XgridDRMAA, available here: http://code.edbaskerville.com/xgrid_drmaa/XgridDRMAA.dmg Thanks for all your help with the spec—especially Daniel Templeton, whose helpful responses and JNI code made the Java implementation extremely easy. It's not "DRMAA-compliant" yet, nor is it likely to be until Apple makes some changes to Xgrid, but it should be quite possible to write useful programs that should run unmodified between, say, Xgrid and Sun Grid Engine. --Ed
