Order is data set that includes request to buy or sell specific computing resources. Order is a placed offer on the Marketplace:
- by Supplier to rent resources - ASK order,
- by Customer to buy resources - BID order.
Supplier creates ASK orders not directly but only configuring ASK plans. Now this function is available in SONM CLI.
Customer creates BID orders directly. Now this function is available in SONM CLI.
Further will be described the BID order. To get information about ASK plan and ASK order please go to the ASK plan page.
BID order parameters
BID order is characterized by the following parameters:
- duration - duratation of the rent in format of XhYmZs, for example: 12h23h45s. If the duration is 0, the deal will be spot, else forward.
- price - order rent price in USD/h or USD/s, for example: 4.23 USD/h.
- order type - order type: BID. The value appears automatically after creation.
- creator - creator's Ethereum address. The value appears automatically after creation.
- counterparty - counterparty's Ethereum address. Is optional, restricts buying resources only from specified address. Allways use copy-paste to set this value.
- blacklist - additional blacklist to be used; set Etehreum address of blacklist owner.
- identity - minimal [identity level]() of counterparty: anonymous, registered, identified, professional.
- tag - an arbitrary string tag for the order. BID order tag will be available in the deal.
- overlay - indicates whether overlay networking is required: true or false.
- outbound - indicates whether outbound connections are required (internet access): true or false.
- incoming - indicates whether inbound connections are required and public IP should be present on worker: true or false.
- benchmarks - required values of the resources benchmarks:
- cpu-cores - required CPU cores. This only specifies mininum number of CPU threads, not their scheduling. Can be fractional, for example: 3.5. To specify amount of computing power use cpu-sysbench- parameters.
- cpu-sysbench-one - CPU benchmark with sysbench for one core, for example: 1528.
- cpu-sysbench-multi - CPU benchmark with sysbench for all cores, for example: 5677. Can be less than cpu-sysbench-single when you need less than 1 core.
- ram-size - RAM amount in bytes, for example: 2000000000.
- storage-size - maximum storage size in bytes, for example: 500000000. Note that if the parameter is not specified, then the minimum value in 64Mb is still allocated.
- net-download - maximum download speed in bits/s, for example: 25000.
- net-upload - maximum upload speed in bits/s, for example: 40000.
- gpu-count - GPU count (1 for each GPU), for example: 2.
- gpu-mem - GPU memory for 1 GPU in bytes, for example: 4096000000.
- gpu-eth-hashrate - total Ethereum mining hashrate for all GPU in hashes/s, for example: 25000000.
- gpu-cash-hashrate - total ZCASH mining hashrate for all GPU in sol/s, for example: 250. Used for the algorithm Equihash (200.9).
- gpu-redshift - total Redshift rendering benchmark for all GPU in 1/s, for example: 330.
BID order example (on github):
price: 2.5 USD/h
# optional - restricts buying resources only from specified address
# counterparty: 0x8125721c2413d99a33e351e1f6bb4e56b6b61567
# identity level of the counterparty. Can be "anonymous", "registered", "identified" and "professional"
SONM performs decentralized orders matching according to the orders properties.
BID order lifecycle
- Customer places a BID order directly on the Market using CLI. Order cann't be changed, only can be cancelled by Customer.
- At this moment the amount of SNM tokens for the first period (1 hour for the spot, 24 hour for the forward deals, or if it less - all deal price) are frozen on the Market from the Customer's account.
- When the order is placed Customer's Client node automalically monitors the Market searching appropriate ASK orders to match. If the matching ASK is found Worker initiates deal creation.
- When the deal is settled, BID order is automatically cancelled by Market smartcontract. Read about deal and billing on the Deal page.
- When the deal has finished, Customer may place a BID order using CLI again.
Note that Customer also can buy resources without placing BID orders but using quick-buy function. See CLI Guide and GUI Market Guide.
ASK plan and ASK order lifecycle are described on the ASK plan page.
