The problem is that we don't know which network architecture we can choose. The alternatives are: 1) switched Fast ethernet 2) Myrinet LAN 1) Is well known and much cheaper. 2) Provides better performance due to latency times and bandwidth. Can you give me any recomendation or advice? Is the performance improvement (using myrinet) worth the cost difference? Do youn know of any other alternative we can use? Any help or advice would be welcome. Thanks in advance Greetings from SPAIN.
