[mvapich-discuss] problem on mvapich2-1.8.1 checkpoint/restart with BLCR

[Raghunath]

Suja,

There is a known bug in the 1.9-alpha2 version that causes the
configure script to look for FUSE when Checkpoint-Restart support is
enabled, even after adding the "--disable-ckpt-agregation"  flag. The
fix for this will be available as part of the next release.

Meanwhile, you can work around this bug by using the alternative
"--without-fuse" flag in place of "--disable-ckpt-agregation".
