Re: cusolver document

Sorry, the doc for the cusolver Fortran interfaces is not available yet. Suffice it to say, there are no surprises in the interfaces, they correspond 1-1 with the documented cusolver arguments. Here's an example: USE cusolverDn, only : cusolverDnHandle, cusolverDnCreate, cusolverDnDestroy USE cusolv...

Re: Fortran async I/O issue

I think I was able to reproduce your problem. I wrote a loop over your call, writing 64 Mbytes each time in a loop. I got this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 FIO/stdio: Invalid argument FIO-F-/WAIT/unit=122/error code returned by host stdio...

Re: Fortran async I/O issue

We can try that here. Can you post a few snippets of how you are doing the i/o operation and the wait? We will see if we can reproduce it and send it to engineering. Might just be an improper int vs. size_t passed to an underlying system function. Or, we are using an interface that only takes an int.

Re: Possible bug using OPTIONAL in F2003 abstract interfaces

This looks like a bug in our compiler. We are tracking this as FS#28361.
