Request for IPSC applications/benchmarks Hello, I am doing some development work in Linda on an IPSC/2. In order to objectively evaluate the performance of programs I write, I need to compare them with programs that are generally accepted to have good performance on this machine. Does anyone out there have a program that performs well (not necessarily outstandingly) for its application area and for this machine? If it's not too large, I would like to rewrite it in Linda and compare performance. I need either source code that I can compile (this is preferable, so that I can make sure I'm comparing apples to apples), or performance information along with an algorithm, with enough information that I can reproduce the algorithm in Linda and extrapolate the performance results to whatever machine configuation I run it on. Lacking either of the above, I would appreciate at least minimal information, such as "We achieved XXX MFLOPS on a 32 processor machine without vector units, doing Gaussian Elimination with partial pivoting", so that I can at least make a meaningful comparison with something I write. Thank you, Edward Segall -- uucp: {...}!rutgers!caip.rutgers.edu!segall arpa: segall@caip.rutgers.edu

> > Request for IPSC applications/benchmarks > I think our Public Domain raytracing algorithm (VM_pRAY) may have some interest for you. It runs on an iPSC/2 and is based on a distributed virtual memory for the database (which can be particularly large for this algorithm). I think I you want to rewrite the code in Linda you can do it with minor changes: parallel code is limited for two services, one service for the shared database accesses (using software paging mechanism) and one service for the work balance (dynamic distribution of the pixel map). The source code of VM_pRAY is available from our site (irisa.irisa.fr (131.254.2.3)) with a ftp anonymous access (directory iPSC2/VM_pRAY). -didier. -- Didier Badouel @ IRISA, Rennes, France (badouel@irisa.fr) --
