Answers differ for ParMETIS tests on linux platforms
|
|
Suspect difference in rand() is the cause.
|
|
On linux, rand() returns values in the range 0 to 2147483647; on
|
|
Solaris, it returns values in the range 0 to 32767. (See definition of
|
|
RAND_MAX in <stdlib.h>.)

|
|
- Differences in answers between linux and sun arise due to round off
|
|
in computation of xy in Zoltan_RIB_inertial2d on processor two for last
|
|
cut (between partitions 3 and 4). Statement xy += xdif*ydif yields
|
|
slightly different results, despite identical input values of xy, xdif, and
|
|
ydif. The resulting cuts are different enough on the two platforms that
|
|
node 19 falls on different sides.
