This is the actual assert
pvfs2-client-core: src/client/sysint/sys-io.sm:1860:
io_post_write_ack_recv: Assertion `ret == 0' failed.
Interesting.. It looks like job_bmi_recv() was returning 1 indicating
immediate completion for the final write ack's receive which seems
impossible..
Sam, Phil: That shouldn't happen, right?
Right. It should be returning an error if it fails -- never 1.
Anthony, which BMI method (tcp, ib, gm) are you using with your setup?
I don't see this on my setup even with -threaded client-cores...
Sam: WHat is the reason for building the -threaded version of pvfs2-
client-core?
Multiple threads allows for a device thread to handle unexpected
operations from the kernel module. We were seeing minor performance
improvements with some tests we did, especially for smaller IOs.
-sam
I forget now..BMI on client drives progress using threads?
The main thread/event loop is certainly uni threaded as far as I
can tell.
thanks,
Murali
