[mpich-discuss] Asking standard checkpoint in MPICH2

[Bagus Jati Santoso]

Hi Darius,

OK. Thank you for answer my email.

And how about MPICH-1.2.1.p1? The more stable version one..
Do I need to install BLCR first for this version?

Since 1.2.p1 have a support for BLCR too, which version do you suggest to
work with BLCR package, 1.2.1.p1 or 1.3a2 ?

Thank you very much,

Bagus
