[Darshan-users] Multithreaded applications crash when using LD_PRELOAD

[Phil Carns]

Just a quick update on this thread: there is a pre-release version of 
Darshan (2.2.8-pre1) available on the Darshan download page now that 
includes a fix for the MPI_Init_thread() problem that Myriam reported.

2.2.8-pre1 also happens to fix a compatibility problem with MPI-3 (MPICH 
3.x to be specific) which may be of interest to some folks as well.  We 
will turn this into an official 2.2.8 release relatively soon.

thanks,
-Phil
