Is there anyone having experience with BSPLib on Clusters of
Workstations?

I installed BSPLib v1.4 for both shared memory (SHMEM_SYSV) and clusters

of workstations (MPASS_TCPIP) on a Sun Ultra-2 running Solaris 5.6.

Then I run the example programs coming with the package for testing
purposes. The shared memory version run without any problems. But I had
some problems with the NOW version.

When I run eg. the "helloworld" program on two processors, I got an
error
message:

>>coffeepot bsplib_progs $ bsprun -npes 2 helloworld
>>
>>BSP/TCP Library(dishwasher.cs.rpi.edu): error in
setsockopt(SO_SNDLOWAT)1
>>call (result = -1, errno = 99).
>>BSP/NOW Master: Abort received from BSP pid 1 (code = 2).

Even with single processor, NOW version of BSPlib caused a problem. It
gives the correct output but it does not halt:

>>coffeepot bsplib_progs $ bsprun -npes 1 helloworld
>>Hello BSP Worldwide from process 0 of 1
>>yy

And the "yy" at the end of the output is a questionmark... (looks
like some kind of memory violation...)

I am doing research on "Harvesting idle processor cycles on
nondedicated Network of Workstations", and want to use BSPlib for
implementation. I would be very pleased if you would help me in solving
these problems.

Thank you very much.
