[mvapich-discuss] Assertion failure in mvapich 1.2rc2

[Åke Sandgren]

Hi!

I'm running VASP (4.6.35) built with mvapich 1.2rc2 built with the
pathscale compiler (3.2) and for some inputs i get

Assertion failed in file ibv_rndv.c at line 645:
sreq->mrail.rndv_buf_off == sreq->mrail.rndv_buf_sz

This is a bit hard to debug since it takes ~1.5hours before i happens.

Any ideas of why this would occur?
And more importantly how to fix it.
