Hi, I am not a Fortran expert by any means but have been searching for a solution to a particular problem that I'm having and have not had any success in finding a solution. Any help or feedback would be much appreciated.

I'm doing an integration piece between a Java front-end and a very mathy chunk of fortran we've written. We've got it being loaded and executed properly.
The one annoying thing is that I'm using the JVM to subscribe to SIGINT, so I can do some persistence-ee things if the user hits Ctrl + C on one of our command line tools. This works well, except for that if I load the fortran dll after the signal handler was registered with the JVM, the fortran DLL appears to over-write the signal handler I put in with its own.

My research group is now considering buying a IVS compiler and install it to one computer. Then I found the cheapest one is:
Intel® Parallel Studio XE Composer Edition for Fortran Windows - Named-user Academic (Service & Support Renewal Pre-expiry) [Electronic Delivery]
It is only $199. So what does Service & Support Renewal Pre-expiry mean? My group will use it to run some short fortran codes. So any suggestions if we buy this one?
For the code below I am using Intel Fortran 184.108.40.206 (64-bit) on Windows 7. Multiple images attempt to write (in orderly fashion) to a file that has been created with the SHARE='DENYNONE' attribute; and yet only the last image writes to it.
I may be overlooking something here, but this behavior puzzles me.
In the trivial code below, all images perform some task, which output needs to be gathered on the first image (for further processing, for instance). Two strategies are implemented: the first one consists in having image 1 go hunt for the results on other images; the second one consists in all images writing to the local coarray of image 1.
My questions are the following:
I am looking for a strategy to implement the merging of file output when a coarray program is executed.
Assume I have a code being executed on multiple images. Ideally, the overall behavior of the code and some intermediate results would be documented in a small number of log files (possibly just one). At regular intervals (but not too frequently), the slave images would add content to these *.log files.
I am a bit at a loss to find an elegant solution to this problem, and if somebody here could share their experience with this I would be very grateful!
